1. The basics of patents
1.1. What is a patent?
A patent is a legal right granted by a national or regional authority that gives an inventor exclusive control over their invention for a limited period, typically up to 20 years from the filing date.
In practice, a patent gives the owner the right to stop others from making, using, or selling the invention without permission.
In exchange for this exclusive right, the inventor must publicly disclose how the invention works. This disclosure helps advance knowledge and allows others to build on it once the patent expires.
1.2. What makes an invention patentable?
To qualify for a patent, an invention must meet the following core criteria:
Novelty: It must not have been publicly disclosed anywhere in the world before the filing date.
Inventive step (non-obviousness): It must involve a technical advancement that would not be obvious to someone skilled in the field.
Industrial applicability / utility: It must be capable of being made or used in some form of industry.
Some types of subject matter are excluded from patentability (such as abstract ideas, mathematical formulas, or discoveries of natural phenomena).
Once granted by a patent office, a patent gives its owner the right to prevent others from making, using, selling, or distributing the invention without permission. After the patent expires, the invention enters the public domain and can be freely used by anyone.
1.3. Why are patents important?
Patents are a powerful driver of innovation, business growth, and competitive advantage. By granting temporary exclusivity in exchange for public disclosure, they encourage new inventions while sharing knowledge with society.
When you manage patents effectively, your portfolio can:
Protect your market share
Attract investment and increase valuation
Generate revenue through licensing or sales
Reduce legal and competitive risks
Open up new markets and strengthen negotiating positions
Because patents are territorial and costly to maintain, a strong patent strategy is essential. Beyond protection, patents function as strategic assets that can support partnerships, influence disputes, and power your next stage of growth.
1.4. Patent vs. trademark, trade secret, copyright
In comparison to patents other intellectual property rights protect different kinds of assets and work in very different ways.
What is a trademark?
A trademark protects the distinctive elements that identify your brand, like a name, logo, tagline, packagingdesign, or even a sound. Its role is to help customers recognize and trust your products or services, and to stop competitors from using confusingly similar branding.
By registering a trademark, businesses gain exclusive rights to its use within specific goods or services classes and in the jurisdictions where it is registered. This enables companies to build recognition, trust, and long-term brand value.
How are trademarks different from patents?
Patents protect technical inventions, while trademarks protect your brand identity. As patents expire after about 20 years, trademarks can last indefinitely if they are used, renewed, and enforced.
How long does trademark protection last?
Unlike patents, trademarks don’t have a fixed expiry date. As long as they’re:
Actively used in commerce
Renewed on schedule
Properly enforced against misuse
…protection can continue indefinitely.
What is a trade secret?
A trade secret is confidential business information that provides a competitive advantage and does not require registration. This makes them a flexible part of your intellectual property strategy, especially for innovations that are hard to reverse-engineer or not easily defined in a patent.
To qualify as a trade secret, the information must:
Be secret (not generally known or easily accessible)
Have commercial value because it is secret
Be subject to reasonable steps to keep it confidential (e.g., NDAs, restricted access, encryption)
Examples of trade secrets include:
Proprietary formulas or recipes
Manufacturing processes
Algorithms or software source code
Business strategies or customer lists
How are trade secrets different from patents?
Patents require you to publish your invention, while trade secrets protect value by keeping information confidential. Patents give you exclusive rights but only for a limited time. Trade secrets can (in theory) last forever but once the information becomes public, the protection is lost. How long does trade secret protection last?
A trade secret can stay protected indefinitely, but only if:
The information is not publicly known
You take reasonable steps to keep it confidential (e.g., NDAs, access controls)
If the information becomes public, the protection is lost.
Copyright protects original creative works, by protecting the expression of an idea, not the idea itself. It applies automatically once a work is created and fixed in a tangible form.
This includes works like:
Books, articles, and blogs
Music and sound recordings
Artwork and photography
Films and videos
Software code and digital designs
Copyright grants the creator exclusive rights to:
Reproduce the work
Distribute copies
Perform or display it publicly
Create adaptations or derivative works
How are copyrights different from patents?
Patents protect technical inventions, while copyright protects creative expression. Patents must be registered and examined, while copyright applies automatically. Patents last about 20 years, but copyright usually lasts for the author’s life plus 70 years.
How long does copyright protection last?
Copyright typically lasts much longer than patents:
In most countries, protection extends for the author’s lifetime plus 70 years, depending on local law.
Protection is automatic, you don’t need to file anything to own it.
But registering your copyright (where possible) strengthens your ability to enforce it in legal disputes.
2. What are the different types of patents?
Patents can be divided into different categories depending on what they protect. Each category serves a different purpose, with its own requirements and duration of protection.
2.1. What is a utility patent?
A utility patent protects the functional aspects of an invention, how it works and what it does. This is the most common type of patent worldwide, covering:
Machines (e.g., a new type of engine)
Processes (e.g., a method for purifying water)
Compositions of matter (e.g., a new pharmaceutical compound)
Articles of manufacture (e.g., a medical device)
How long can a utility patent last?
A utility patent generally lasts for 20 years from the filing date of the application, as long as the necessary patent renewal or maintenance fees are paid.
In many other jurisdictions, patent renewal fees are due annually from the filing date. If fees are not paid, the patent will lapse before the full term. Some jurisdictions allow adjustments or extensions (for example, pharmaceutical patents in the EU can be extended with supplementary protection certificates).
Key point: Like all patents, utility patents require public disclosure of how the invention works. Once the protection ends, the invention enters the public domain, allowing anyone to use or build upon it freely.
2.2. What are design rights?
A design (registered design, industrial design, design patent) protects the ornamental appearance of a product, its shape, surface pattern, or visual style, rather than its functional features. Unlike trademarks, which identify and distinguish brands in the marketplace, design patents are tied to the design of a specific product or invention.
What can be protected by a design patent?
Unique product shapes (e.g., the distinctive outline of a smartphone)
Decorative surface patterns (e.g., intricate designs on packaging)
Aesthetic design elements (e.g., the visual style of a piece of furniture)
Design vs. patent
Designs: Focus on how a product looks (its ornamental or aesthetic design).
Patents: Focus on how a product works, its technical or functional features, including processes, machines, compositions of matter, and products.
Some products can be protected by more than one type: for example, a smartphone may have a design patent for its physical appearance, a utility model for a new mechanical feature, and a utility patent for its internal technology.
How long can a design last?
The duration of the protection and the need for maintenance or renewal fees for design rights vary based on jurisdictions, but generally designs offer long-term protection, usually from 15 to up to 50 years, with less frequent need for renewals. In the United States, design patents do not need maintenance at all, while under the EUIPO legislation, renewals are required every 5 years.
2.3. What are plant-related IP rights?
Plant patents (United States only)
A plant patent is a U.S. right that protects new and distinct plant varieties that are asexually reproduced (propagated without seeds, e.g., by grafting, budding, or cuttings).
What can be protected by a plant patent?
Novel ornamental plants
Distinct fruit or nut trees
Unique flowering plants
Any asexually reproduced plant that is new, distinct, and stable
Limitations:
Tuber-propagated plants (e.g., potatoes) are excluded
Plants discovered in the wild cannot be patented
Protection applies only if the variety can be consistently reproduced asexually
Plant Variety Rights (PVRs) / Plant Breeders’ Rights (PBRs) (International)
Outside the U.S., most countries do not use plant patents. Instead, they rely on Plant Variety Rights (PVRs) or Plant Breeders’ Rights (PBRs), usually based on the UPOV Convention.
What can be protected?
Both seed-propagated and asexually propagated plant varieties
The variety must be new, distinct, uniform, and stable (DUS criteria)
How long can plant variety rights last?
Commonly 20–25 years. Longer protection for some plants (e.g., up to 30 years for vines and trees, depending on the country)
Key takeaway:
In the U.S., plant protection comes through plant patents, covering only asexually reproduced varieties.
Internationally, protection is usually through PVRs/PBRs, which are broader (covering both seed and asexual propagation) and have slightly different duration and criteria.
2.4. What is a utility model?
A utility model (sometimes called a “petty patent” or “innovation patent”) protects the functional aspects of a product, typically covering incremental improvements rather than groundbreaking inventions. It is often described as a “short-term patent” because it offers a faster, cost effective route to protection but with narrower scope compared to standard patents.
What can be protected by a utility model?
Small technical improvements (e.g., a more efficient clasp mechanism)
Functional product features (e.g., an improved bottle cap design)
Minor adaptations of existing technologies (e.g., a new shape that enhances usability)
Utility model vs. patent
Utility models: Protect new technical solutions or functional features that may not meet the higher “inventive step” requirement of patents. They are quicker to obtain, usually cheaper, but offer shorter-term protection.
Patents: Protect major technical innovations with a higher inventive threshold, offering broader protection but requiring longer, costlier examinations.
Some inventions may qualify for both. For example, a kitchen tool could have a utility model protecting a novel handle mechanism, while the broader technical invention could be covered by a patent.
How long can a utility model last?
Protection typically lasts 7 to 10 years, depending on the jurisdiction, and unlike patents, renewals are often limited or shorter in duration. Many countries, including Germany, Japan, and China, recognize utility models, but they are not available in the U.S., U.K., or Canada.
3. What is the process of patent applications
3.1. How to prepare for patent filing
Step 1: Check patentability
First, confirm that your invention meets the basic legal requirements for patent protection (see Section 1.2 What makes an invention patentable?). It must satisfy three standards: novelty, inventive step, and industrial applicability.
At this stage, you should also be aware of excluded subject matter, for example, abstract ideas, natural discoveries, or certain medical methods may not qualify depending on the jurisdiction. Consulting a patent attorney or agent early can help you assess eligibility and avoid pursuing non-patentable inventions.
Step 2: Conduct a prior art search
A prior art search helps you understand whether your invention is truly new. Patent offices only grant protection for inventions that are novel and non-obvious, so reviewing existing patents, scientific literature, and other public disclosures can help you:
Avoid wasted effort on inventions that cannot be patented.
Shape your claims to highlight what is truly original.
Reduce the risk of rejection during examination.
Public databases are excellent starting points:
Espacenet (EPO): European patents and applications.
USPTO Patent Search: U.S. patents and applications.
Google Patents: global coverage with easy keyword search.
WIPO PATENTSCOPE: international (PCT) applications.
Keep in mind that prior art also includes non-patent literature such as research articles, product manuals, or technical blogs. While self-searches are useful, many applicants rely on professional search services or patent attorneys to ensure a more thorough review.
Private or subscription-based patent search databases offer more advanced capabilities, including:
Better filtering and search accuracy (e.g., by legal status, assignee history, or claim language).
Broader coverage, including utility models, design rights, and non-patent literature.
Deeper analytics for competitor tracking, portfolio management, and market insights.
Examples:
Lens.org: Free, with more analytical tools than most public databases.
PatBase: Subscription-based, strong global coverage and refined search.
Derwent Innovation: Known for curated abstracts and high-quality indexing.
When to consider private tools: If you’re in a highly competitive industry, planning global filings, or need freedom-to-operate analysis.
Pro tip: Even if you start with public tools, having a patent attorney or search professional perform a final, multi-database search before filing greatly reduces the risk of overlooking critical prior art.
Step 3: Match your patent filing strategy to your business goals
Patents are territorial rights: protection only applies where you file and maintain patents. Decide early whether to:
Focus on a single market (national filing).
Target multiple European states (EPO filing or Unitary Patent).
Plan for global coverage (PCT filing).
Your patent filing strategy should reflect your commercial objectives whether that means protecting a single product launch or building an international portfolio.
Step 4: Draft your patent application
Once you’ve researched the prior art and confirmed your invention’s patentability, the next step is to draft a complete and well-structured patent application. A strong filing typically includes:
Detailed technical description Explains how the invention works and what makes it unique. Include enough detail that someone skilled in the field could reproduce the invention.
Patent claims Claims define the legal scope of protection. There are different types:
Independent claims: cover the essential features of your invention and provide broad protection.
Dependent claims: add limitations or variations and may remain valid even if broad claims are rejected.
Method/process claims: cover actions or steps (manufacturing processes, medical treatments, etc.).
Patent drawings and diagrams Visuals that support the description and claims. Required if they help explain the invention.
Abstract A concise summary (usually under 150 words) that provides a quick technical overview for examiners and search databases.
Helpful tools: Platforms like PowerPatent or AI-assisted drafting tools can help structure your application more efficiently. However, claim drafting requires legal and technical precision. It’s highly recommended to consult a patent attorney or agent for accuracy.
Step 5: Timing and confidentiality
Timing is critical. In many countries, any public disclosure before filing through a presentation, publication, or product launch destroys your chances of patenting.
United States: allows a 12-month grace period after disclosure.
Europe, China, Japan (and most other jurisdictions): apply absolute novelty rules, meaning you must file before any disclosure.
To stay safe, always file before going public.
Step 6: Prepare for patent filing logistics
Before filing, make sure you’re ready to submit through the relevant patent office portal:
USPTO Patent Center (United States): requires a verified USPTO.gov account. A non-provisional application must include a specification, at least one claim, an abstract, any necessary drawings, and a signed inventor oath or declaration. A provisional application only requires a specification and drawings (no claims or declaration).
MyEPO services (Europe): applications require Form 1001 (request for grant), a description, claims, drawings (if needed), and an abstract. Some missing parts can be added later within strict deadlines.
Follow the formatting rules (DOCX, PDF, XML, or as required by your office).
3.2. How to file a patent application
The process for filing a patent varies by region, but the key steps are similar worldwide: submit a complete patent application to the relevant patent office, undergo examination, and if successful, receive a grant.
How to file a patent in the United States
In the U.S., inventors can choose between two routes: a provisional application or a non-provisional (full) application.
Provisional application: This secures an early filing date and gives you 12 months to file a non-provisional application. It requires only a basic description and any necessary drawings, and it is not examined for patentability. Filing is faster and less expensive, making it useful if you need time to refine your invention, seek funding, or conduct further testing. However, a provisional cannot be extended or renewed, provides no enforceable rights on its own, and may fail to support later claims if drafted too vaguely.
Non-provisional application: This is the formal request for patent examination and grant. It must include a full specification, detailed claims, and all required documents. Non-provisionals are examined for novelty, inventive step, and industrial applicability. They are more expensive and time-intensive to prepare but move you directly toward a granted patent.
Differences between provisional vs. non-provisional patents
While the U.S. is the best-known jurisdiction offering provisional applications, similar systems exist in Australia, Canada, India, and Singapore. In most other regions including Europe, China, and Japan only complete non-provisional applications are available.
Key differences include:
Purpose: Provisionals lock in a priority date while giving inventors 12 months to refine or expand their application. Non-provisionals initiate the actual examination and grant process.
Detail required: Provisionals require only a basic description and optional drawings, while non-provisionals require a full specification, claims, and supporting documents.
Deadline: A provisional must be converted into a non-provisional or PCT filing within 12 months (rare exceptions apply). Non-provisionals do not have this limitation.
Cost: Provisionals are cheaper upfront, while non-provisionals involve higher initial costs but lead to enforceable rights once granted.
Pros and cons: Provisionals are fast, flexible, and inexpensive but do not provide enforceable rights. Non-provisionals demand greater investment but allow direct progress toward a granted patent.
Where to file a patent
Your choice of where to file a patent depends on where you need protection. Patents are territorial rights, which means they only apply in the countries or regions where they are granted and maintained.
Filing a patent with national patent offices
If your market is limited to one country, filing directly with that country’s national patent office is usually the simplest and most cost-effective option.
How to file a patent in Europe (EPO and Unitary Patent)
For protection in multiple European countries, you can file a single application with the EPO. If granted, the patent must be validated in each designated member state, and some states require translations or additional fees.
How to file a patent online?
USPTO (United States): Applications can be filed through the Patent Center using a verified USPTO.gov account.
EPO (Europe): Applications are filed via the MyEPO services portal.
Both systems also allow applicants to file international (PCT) applications electronically, acting as a receiving office for WIPO.
3.2.1. What are the global patent systems
The Patent Cooperation Treaty (PCT)
The PCT is like a one-stop entry point for multiple countries. It allows you to file one international patent application that’s recognized by over 150 member states.
Why use PCT:
Secure an early filing date while keeping your options open.
Delay expensive, country-by-country filings until you know where the invention has market potential.
Simplify the first stage of filing, one set of documents, one initial fee.
How PCT works:
International phase: You file through WIPO (World Intellectual Property Organization). This doesn’t grant a patent, but it buys you time (usually 30–31 months from your priority date).
National phase: You choose which countries to enter. Each patent office then examines your application under its own laws.
Patent maintenance fees: Once you’re in the national phase, each country has its own maintenance schedule and costs.
Pro tip: Use the PCT if you’re still testing the market or seeking funding, it keeps your options open without locking you into every country from the start.
European Patent Convention (EPC)
The EPC lets you apply for a single European patent covering up to 39 member states. The European Patent Office (EPO) handles the filing, search, and examination stages.
What happens after EPC grant:
You must validate your patent in each country where you want protection. This may require paying national fees and submitting translations.
Once validated, the European patent becomes a bundle of national patents, each with its own patent renewal fees.
Why EPC useful:
One examination process instead of multiple national filings.
Flexible, you choose where to validate based on your strategy and budget.
Pro tip: If you want easier post-grant management in Europe, look into the Unitary Patent option (see below).
The Unitary Patent and UPC
The Unitary Patent (UP) is a new option through the EPO that allows you to maintain protection across multiple EU countries with one patent renewal fee and no separate national validations.
Benefits of a unitary patent:
Lower administrative costs over the lifetime of the patent.
No need for multiple translations or national renewals in participating states.
Covers all EU member states that have joined the system (more are expected to join over time).
The Unified Patent Court (UPC):
A single court system for participating countries.
Handles disputes for both Unitary Patents and, in some cases, traditional European patents.
Offers faster and more consistent enforcement.
Pro tip: The UP is ideal if you want broad EU coverage with minimal post-grant admin. But remember, it only covers participating states, so you may still need separate protection in non-participating countries.
Key takeaway: Choosing the right system depends on your markets, budget, and timeline.
PCT = Delay big costs and keep options open globally.
EPC = One route to multiple European countries, with post-grant flexibility.
UP + UPC = Streamlined patent maintenance and enforcement across participating EU states.
3.3. What happens during patent examination?
Patent examiners review your application for:
Formalities: ensuring documents, fees, and formatting are correct.
Substantive issues: checking that the invention is novel, non-obvious, and industrially applicable.
In some jurisdictions (e.g., Germany, China, Japan), you must file a separate request for examination within a set timeframe, or the application will lapse.
What are office actions under a patent examination?
Examiners issue formal communications called office actions, which may:
Outline objections to clarity, claims, or sufficiency of disclosure.
Identify prior art that conflicts with your invention.
Request clarifications or amendments.
Applicants can respond by:
Submitting arguments to counter examiner objections.
Amending claims to narrow or clarify scope.
Adjusting documents to meet compliance.
Several rounds of office actions and responses may occur before a final decision is reached.
Possible outcomes of patent examination
At the end of examination, the application may result in:
Grant: if all requirements are satisfied.
Refusal: if objections cannot be overcome.
Withdrawal: if the applicant chooses not to proceed.
In case of refusal, appeals may be possible (e.g., USPTO’s PTAB or the EPO Boards of Appeal).
3.4. When are patents granted or published?
Once your application meets all requirements, it proceeds to grant and publication:
What does patent grant mean?
Once granted, your patent rights are officially recognized and enforceable within the jurisdictions they were filed. At this stage:
The patent office issues a grant certificate.
In the U.S., an issue fee must be paid before grant.
In Europe, the grant is announced in the European Patent Bulletin.
Granting gives you the right to exclude others from making, using, or selling your invention but enforcement is your responsibility.
When are patents published?
Initial publication: Most applications are published 18 months after filing or priority date, even before examination is complete. This makes details available in official databases like USPTO PAIR, Espacenet, or WIPO Patentscope.
Publication of grant: Once granted, the final text of the patent (claims and description) is also published, marking the enforceable version of your rights.
Regional notes: After grant, you must validate your European patent in each chosen member state, which may involve translations and fees. Since 2023, the Unitary Patent offers a cost-effective alternative, providing protection across participating EU states with a single patent renewal fee.
3.5. What are the costs of patenting?
These are the costs you’ll encounter from the moment you decide to file a patent until the day it’s granted. They vary significantly depending on the jurisdiction, the complexity of your invention, and whether you use professional help.
Filing fees: Charged by the patent office to process your application.
Search fees: For the novelty search conducted by the patent office (sometimes included in examination fees).
Examination fees: Paid when your application enters substantive review.
Grant or issue fees: Charged once your patent is approved.
Additional claim fees: Applied in some offices if you exceed a set number of claims.
Professional service fees: Patent attorney fees for drafting, filing, and handling office communications.
Translation fees: Required when filing in multiple jurisdictions with different official languages.
Drawings and illustrations: Professional patent drawings, if needed.
4. How can you maintain a patent?
4.1. What is a patent renewal?
A patent renewal also known as a patent annuity or patent maintenance is a recurring payment required to keep a granted patent in force. If patent renewal fees are not paid on time (even after the grace period), the patent will lapse, and the owner loses rights.
While patent filing has been somewhat standardized through international treaties, patentrenewal rules remain very different from one country to another. Knowing these differences is critical to avoiding missed deadlines, unexpected costs, or accidental lapses.
European Union (EPO & Unitary Patent)
Duration: Up to 20 years from the filing date.
Before grant: Fees are paid directly to the European Patent Office (EPO).
After grant: Patent renewals must be paid separately in each selected country unless you choose the Unitary Patent, which allows a single payment to cover multiple member states.
Patent renewal frequency: Annually, starting from the last day of the month in the second year from the filing date.
Key challenge: Post-grant IP renewals require coordination with multiple national offices, and sometimes translations.
United States (USPTO)
Duration: Up to 20 years from the filing date (most patents).
Patent maintenance frequency: Three times only, at 3.5 years, 7.5 years, and 11.5 years, the first payment is due at 42 months after the grant.
Discounts: Small and micro-entities can pay significantly reduced fees.
Japan (JPO)
Duration: Up to 20 years from the filing date.
Patent renewal frequency: Annual, starting from the fourth year after the filing date. The first three years are paid together atgrant
Special rule: The first renewal is paid 30 days after the grant date to the Japan Patent Office (JPO). This payment must cover the first three patent annuities.
China (CNIPA)
Duration: Up to 20 years from the filing date.
Patent renewal frequency: Annual, starting the year after grant.
Key difference: The first patent renewal is paid 2 months after the grant date to the State IP Office of the People's Republic of China. All subsequent annuities must be paid annually on the anniversary of the filing date.
Quick takeaway: Patent renewals are territorial, you must pay separately in every country where you want protection. Even a strong international filing strategy can fail if maintenance deadlines aren’t tracked carefully in each jurisdiction. Find out more about each jurisdiction's renewal fee structures.
4.2. What are patent renewal fees?
Once your patent is granted, keeping it in force requires ongoing payments, known as patent renewal or patent maintenance fees.
Understanding both the costs and the difference between official and non-official fees is essential for accurate budgeting and patent portfolio management.
4.2.1. What are official patent fees?
Official fees are the standard charges set by patent offices for processing applications, examining inventions, granting patents, and maintaining rights over time. They are fixed per jurisdiction and publicly available.
Jurisdictional differences:
Every country sets its own fee schedule and payment structure. For example:
USPTO (United States): Reduced rates available for small and micro-entities.
EPO (Europe): Single examination fee, with extra charges for additional claims.
Patent renewal (maintenance) fees are typically due annually after grant and tend to increase over the lifetime of the patent. Missing these patent renewal payments can cause your rights to lapse, and reinstatement is not always possible, making careful fee tracking and planning essential.
Fees can vary considerably between jurisdictions, so always check the latest official source before filing or paying patent renewals.
On ourpatent renewal fee database, we cover more than 75 jurisdictions with up-to-date information on renewal due dates, official patent renewal fees, and local requirements.
4.2.2. What are non-official patent renewal fees?
Non-official fees are service-related costs charged in addition to the official fees set by patent offices. They depend on how your patent renewals are managed: in-house, through a law firm, or with a specialized IP service provider.
These costs can vary widely, and transparency is key to understanding exactly what you’re paying for.
Common types of non-official fees:
Transaction fees: Bank or wire transfer costs and payment processing charges. International transfers can add significant costs, especially if the provider’s payment setup isn’t optimized.
Local agent fees: In certain jurisdictions, renewals must be filed via authorized local agents or attorneys. Their fees vary by country and patent annuity year. Some providers still use local agents in countries where they’re no longer required, increasing costs unnecessarily.
Service fees: Charged by the provider managing the patent renewal. Watch for double billing risk: some law firms outsource the work to third-party providers so adding an extra intermediary to this transactional process.
Currency exchange markup/hedging: An extra margin added to cover exchange rate fluctuations. In the industry, these markups often range from 5–30% and are rarely disclosed clearly on invoices, making it difficult to see the true costs. Some providers also keep unused deposits as profit, meaning customers end up paying more than necessary.
4.3. How to handle patent renewal payments
In-house teams: While this can reduce service charges, it requires significant time, reliable tools, and expertise to manage due dates and fee calculations across jurisdictions. Smaller companies may still manage patent renewals in-house, but as the portfolio grows it quickly becomes complex and resource-intensive. Also requires a strong understanding of local rules and the ability to track changes in national regulations.
Law firms: Offer convenience but often at higher cost, with limited visibility into fee breakdowns. Many law firms or patent attorneys outsource their clients’ patent renewals to third-party providers, leading to double charges in the process..
Specialized IP renewal service providers: Focus on automating and streamliningpatent renewals through an intuitive platform. Fees vary by provider, service level, and pricing model (flat fee vs. percentage-based). Transparent providers, like PatentRenewal.com, clearly separate official and non-official fees, showing exact transaction costs, local agent fees, and currency markups.
Key takeaway:
Because non-official fees can differ dramatically depending on your provider and process, clear invoicing that separates official from non-official costs is essential for controlling your patent budget.
When comparing providers, don’t just look at the service fees, but also the total cost of renewals. Some providers hide patent fees within markups or bundled charges.
A free IP renewal cost comparison can help identify hidden costs and provide a clearer picture of potential savings.
4.4. How to avoid overpaying on your patent renewals
Patent renewal fees are not just about the official payment to the patent office. Together, these expenses can eat up as much as 75% of a patent’s lifetime costs. Choosing the right provider can cut your patent renewal expenses significantly.
1. Extra layers of middlemen: Many law firms and service providers still use local agents or attorneys for paying renewal fees for their clients. In many jurisdictions a local agent is no longer legally required, yet some providers still use them, increasing costs unnecessarily due to the extra handling fee..
2. Double service fee: Most law firms outsource their clients’ IP renewals to a renewal service provider, often hiding the extra middlemen from their clients. The result: you pay the provider’s fee and the firm’s “management” fee, even though only one patent renewal was performed.
3. Transaction costs: Every patent renewal payment generates a bank or processing fee, often €2–3 per transaction. If the provider’s setup involves inefficient payment routes, these costs multiply across a portfolio.
4. Hidden currency markups: Patent renewal fees must be paid in local currencies. Some providers add 5–30% on top of the true exchange rate. In some cases, they also hold currency deposits and fail to refund unused amounts, leaving patentees paying for money never spent.
How to avoid overpaying on patent renewals:
Ask for itemized invoices that clearly separate official fees from service, agent, transaction, and currency costs.
Review whether local agents are truly required for each jurisdiction.
Watch for currency markups and ask how unused deposits are handled.
Compare IP renewal providers periodically to check total costs, not just service fees.
For a full breakdown of costs, hidden fees and tips on how to avoid them check out our recent guide with all patent renewal fees explained.
4.5. What happens if you miss a patent renewal payment
Patent systems in most jurisdictions allow a grace period after the patent renewal due date, usually around six months. During this period, you can still pay the patent renewal fee, but with an added penalty called a surcharge.
If the patent renewal fee is not paid by the end of the grace period, the patent will lapse and the rights are lost in that jurisdiction. In some jurisdictions, reinstatement may be possible under strict conditions for example, if the failure to pay was unintentional or occurred despite all due care. However, reinstatement is not guaranteed, can be costly, and procedures differ widely by country.
Because grace period lengths, surcharge amounts, and reinstatement rules vary, patentees must closely monitor deadlines to avoid losing valuable protection.
5. The most common (and costly) patent management mistakes
Small oversights can quickly turn into expensive problems, or even permanent loss of rights. Here are the most common pitfalls to watch for:
5.1. Mistake 1: Poorly written patent claims
Patent claims define the legal scope of your protection. If they’re too broad, too narrow, or unclear, they can:
Weaken enforceability
Leave loopholes for competitors
Make the patent more vulnerable to invalidation (or rejection)
How to avoid poorly written patent claims:
Invest in professional drafting and thorough review before filing.
Ensure terms are clearly defined in the specification and consistent.
Develop a balanced claim strategy upfront, including fallback, narrower claims to withstand prior-art or examination challenges.
Consider jurisdictional standards for clarity, definiteness, and disclosure.
5.2. Mistake 2: Missed patent renewal fees
If you miss a patent renewal fee payment, your patent can lapse after the surcharge (grace) period. Most countries provide a grace period (often 6 months) during which you can still pay with an additional fee. If the renewal is not paid by the end of that grace period, the patent will lapse. Reinstatement is not guaranteed and, in many countries, is impossible.
Countries where reinstatement is not possible:
Mexico
United Arab Emirates (UAE)
Malaysia (after grace period)
Thailand
Countries with strict or limited reinstatement:
China: Restoration only within 2 months of a lapse notice, requiring valid justification; in force-majeure cases, up to 2 years.
Japan: Possible reinstatement if the lapse was unintentional, under a relaxed standard since April 1, 2023. The request must be filed within 2 months after remedying the lapse and no later than 1 year after the lapse.
South Korea: Restoration allowed within 12 months if non-payment was due to reasons beyond your control; even without reason, you may apply within 3 months from the lapse (with penalty).
Germany (EPO/Most of Europe): Reinstatement possible if the deadline was missed despite “all due care.” You must file within 2 months of remedy and within 12 months of the lapse.
United States: Reinstatement possible if the delay was “unintentional,” sometimes even long after lapse, but requires a petition and payment of a reinstatement fee.
How to avoid missed patent renewal fees:
Use automated reminders, IP renewal tools, or a trusted IP service provider to track deadlines across all jurisdictions.
5.3. Mistake 3: Failing to monitor patent status
If you don’t track your patents closely, they might lapse, face challenges, or even get transferred without you knowing. Each of these creates serious legal and business risks.
How to avoid it:
Check your patents regularly in public and national databases, but don’t rely on them alone since updates can lag.
Monitor competitor filings and legal events like oppositions or invalidations that might affect your market.
Use alerts or patent monitoring services for faster updates, and combine them with in-house tracking tools.
Keep communication open between your legal, renewal, and R&D teams so everyone works with the latest status.
5.4. Mistake 4: Confusing abandonment, lapse, and expiry
These terms often get mixed up, but in patent law they mean very different things. Understanding them helps you avoid costly mistakes and know whether your rights can still be recovered.
1. What’s patent abandonment?
Meaning: You stop pursuing a patent application before grant either by withdrawing it or missing deadlines like office actions or fee payments. In some systems, owners can also voluntarily abandon a granted patent.
Key point: An abandoned patent gives you no enforceable rights. Some jurisdictions allow revival if you act quickly and prove unintentional delay or show “all due care.” Others do not.
Example: You miss the deadline to respond to an examiner’s objection, and the application goes abandoned.
2. What’s patent lapse?
Meaning: A granted patent falls out of force because you didn’t pay a patent renewal (annuity) fee.
Key point: A lapsed patent was enforceable, but protection stops until you restore it. Many countries grant a 6-month grace period with surcharges, but rules differ: the US allows reinstatement if the delay was “unintentional,” while the EPO requires proof of “all due care.” Some countries don’t allow reinstatement at all once the grace period passes.
Example: You miss the 10th-year renewal but pay within the grace period, with the surcharge, and the patent comes back into force.
3. What’s patent expiry?
Meaning: A patent reaches the end of its maximum term (usually 20 years from filing for utility patents, shorter for designs and utility models).
Key point: Expiry happens automatically, and once it occurs the invention enters the public domain permanently. In some fields, extensions exist e.g., Supplementary Protection Certificates in Europe or Patent Term Extensions in the US for pharmaceuticals.
Example: Your 20-year term ends, and the patent expires with no way to renew or restore it.
Why understanding patent abandonment, lapse and expiry matters:
Abandonment usually happens through missed deadlines and careful monitoring prevents it.
Lapse is preventable with a solid patent renewal system and awareness of jurisdictional rules.
Expiry is inevitable, but you can prepare by planning product lifecycles and filing new related patents.
Mixing up these terms can cause serious mistakes like assuming you can revive an expired patent (you can’t), or thinking a lapsed right is lost forever when it may still be restorable.
6. How to manage your IP portfolio effectively
Patents are active assets, and like any asset, they need ongoing attention. Every year (or at set intervals), you’ll face decisions about whether to pay patent renewal fees, which jurisdictions to maintain protection in, and how much of your budget to allocate.
Without a clear strategy, it’s easy to:
Miss due dates and lose rights
Overspend on patents that no longer serve your business
Under-budget for future costs, creating financial strain
Even a small patent portfolio requires tracking a surprising number of details and with a larger one, the administrative burden quickly multiplies. When managed manually, every element has to be updated, checked, and coordinated, turning into a process that’s both time-consuming and error-prone. This typically includes:
Tracking patent records: Filing dates, priority dates, grant dates, publication dates, official fee amounts, and payment confirmations must all be logged and kept up to date.
Ongoing deadlines: Patent renewal dates in each jurisdiction, grace periods, examination requests, validation requirements, and extension deadlines need constant monitoring to avoid lapses.
Patent fee monitoring: Annual renewal fees, country-specific surcharges, late payment penalties, and changes in official fee structures must be tracked regularly.
Financial admin: Currency exchange rates, bank fees, deposit balances, and invoice breakdowns all need to be calculated and monitored to avoid hidden costs.
Legal documentation: Powers of attorney, translations, validation documents, and correspondence with patent offices or local agents must be organized and kept accessible.
Pro tip: Modern IP management and IP renewal software can automate much of this work reducing manual effort, cutting the risk of errors, and giving you more time to focus on strategic IP decisions.
6.1. How can an IP renewal software help manage patents?
When you’re managing a handful of patents, a spreadsheet and calendar reminders might work. But as your portfolio matures, especially across multiple countries, manual tracking quickly becomes risky and time-consuming.
IP renewal software automates the repetitive, high-stakes tasks of portfolio management so you can focus on strategic decisions instead of chasing deadlines.
What an IP renewal software can do for you:
Automated IP renewals: Execute file payments directly with patent offices or local agents when they are legally required.
Due date tracking: Alerts you before payments are due in each jurisdiction so you have enough time to give an instruction whether you want to renew or not.
Full transparency on costs: With a clear breakdown of official patent office fees, service provider fees, local agent fees, transaction or bank fees, and hidden currency exchange markups or deposits.
Centralized IP portfolio view: All renewal schedules, annuity years, jurisdictions, and related costs are visible in one dashboard instead of scattered across spreadsheets.
Forecasting & budgeting: Project and analyze future (or past) patent renewal costs and plan cash flow more accurately.
Document storage: Keep renewal confirmations, invoices, and payment records organized and accessible for audits or internal reporting.
Multi-user access: All your legal, finance and R&D teams share the same central overview, with no limited accessibility.
Why using an IP renewal tool is essential:
Missing an IP renewal deadline can mean permanent loss of rights and in many jurisdictions, reinstatement is impossible. The right IP renewal software minimizes this risk while also improving budget control.
Pro tip: Even the best software is only as good as the data you put into it. Make sure your IP portfolio records are complete and accurate before you migrate to a new system.

6.2. How to plan a smart IP renewal strategy
Patent renewals happen on fixed schedules, but those schedules differ from country to country.
Why IP portfolio planning is necessary
Costs grow with your portfolio size, 10 patents today could be 30 in a few years.
IP renewal fees usually increase over time.
Due dates vary, so tracking them manually is risky.
How to build an IP renewal plan
Map every IP renewal date: Create a master calendar showing due dates for each patent in every jurisdiction.
Estimate future costs: Project official and non-official fees for the next 3–5 years to avoid IP budget surprises.
Review each patent’s value before renewing – Consider:
Is the technology still relevant to your products or market?
Does it block competitors or support licensing revenue? Is the jurisdiction still commercially important?
Prioritize high-value patents: Allocate resources to the patents that matter most to your strategy.
Automate reminders: Use IP management software or service providers to alert you before due dates.
Pro tip: Treat renewals as checkpoints for strategic IP portfolio decisions. Every renewal is a chance to ask: Would I file for this patent again today if it didn’t already exist?
7. How to safeguard your patents
7.1. What is patent infringement?
Patent infringement happens when someone uses, makes, sells, or imports a patented invention without the patent holder’s permission. These rights apply only in the jurisdictions where the patent is granted and valid.
While the details of enforcement differ across countries, the core principle remains the same worldwide: a patent gives its owner exclusive control over the invention for a limited time.
What are the types of patent infringement?
Direct infringement: A product or process directly falls within the scope of a patent’s claims and is used without authorization. This does not require intent or prior knowledge of the patent.
Indirect infringement: Involves supporting or encouraging another party to infringe.
Contributory infringement: Supplying components specifically intended for use in a patented invention.
Induced infringement: Actively helping or directing another party to carry out the infringement.
Willful infringement: The infringer knows about the patent and deliberately ignores it. Courts often impose heavier penalties here, such as increased damages and legal costs.
Legal remedies for patent infringement
Courts can respond to infringement in several ways, depending on national laws. Common remedies include injunctions to stop further use, monetary damages to compensate the patent holder, and in cases of willful infringement, punitive damages. Some courts may also award attorney fees or court costs.
How to reduce infringement risks
Run freedom-to-operate (FTO) searches during product development.
Carry out preliminary patent reviews to spot possible conflicts.
Monitor the market for unauthorized use of your technology.
Get legal advice to handle complex cases and enforcement strategies.
Use licensing agreements to gain legal access to patented technologies.
Consider defensive patent insurance to cover potential litigation costs.
Some of the biggest patent battles in history highlight how high the stakes can be. From billion-dollar tech disputes to landmark pharma cases, courts have repeatedly shown how seriously they treat infringement.
7.2. What is defensive patenting and freedom to operate?
Not every patent is about locking competitors out of a market. Sometimes, the goal is to make sure no one else can block you. That’s where defensive patenting comes in.
Defensive patenting means filing patents, or even publishing technical details, to prevent competitors from patenting similar innovations. This can:
Protect your existing products from future legal challenges.
Build leverage in cross-licensing negotiations.
Keep the space around your core technology clear.
You might use this approach to cover:
Small improvements that aren’t core to your business but could create barriers if patented by competitors.
Alternative designs or methods that achieve the same outcome in different ways.
Defensive publications that place your idea in the public domain so no one else can patent it.
Freedom to Operate (FTO) is about knowing you can launch your product without infringing anyone else’s rights. An FTO search looks for active patents in your target markets to identify risks before you commit to manufacturing or marketing.
Why FTO matters:
Prevents costly infringement lawsuits.
Helps you design around existing patents.
Reduces the chance of product recalls or forced market withdrawals.
Pro tip: Combine defensive patenting with periodic FTO reviews especially before major product launches or entering new markets. Together, they keep your innovation pipeline clear and your legal risks low.
7.3. How to monitor your patents
Patent monitoring involves keeping track of new patent filings, granted patents, and changes to existing rights. It helps identify competitor activity, spot potential risks, and stay informed about developments in relevant fields.
Patent monitoring helps you track:
Competitor filings: See where rivals are focusing their R&D.
New technologies: Spot emerging trends and potential opportunities.
Legal status changes: Learn when patents lapse, get abandoned, or are granted.
Monitoring can focus on various aspects:
Technology-focused: Track innovations in a specific technical area.
Competitor-focused: Follow the activity of specific companies.
Geographic-focused: Watch filings in particular countries or regions.
8. How can you get the most value out of your patents?
8.1. How does patent licensing work and why is it important?
Patent licensing lets you give others permission to use your patented technology in exchange for payment or other agreed terms, while you keep ownership. It’s a flexible way to create value from your IP.
Types of licenses:
Exclusive: Only one licensee can use the invention in a defined territory or market.
Non-exclusive: Multiple licensees can use the invention at the same time.
Restricted: Rights are limited by geography, time period, or field of use.
Cross-licensing: Two or more parties exchange rights to their patents, often to avoid disputes and enable broader innovation.
Benefits of patent licensing:
Creates recurring revenue without manufacturing or distribution costs.
Opens new markets through partners with local expertise.
Builds stronger business collaborations and alliances.
Helps avoid litigation and increases freedom to operate through cross-licensing.
Challenges of patent licensing:
Loss of control over how your invention is used.
Dependence on partners to commercialize effectively.
The need for clear, enforceable contracts and ongoing monitoring.
Pro tip: Successful licensing depends on strong agreements. Define scope, territory, and payment terms precisely, and review them regularly to protect both revenue and reputation.
8.2. What is a patent pool and why do companies use them?
A patent pool is an agreement where multiple patent holders license their patents as a group, often through a single administrator. This makes it easier for others to access related technologies without negotiating with each patent owner individually.
Advantages of patent pools:
Lower licensing costs: One agreement covers multiple patents.
Fewer legal disputes: Reduces conflicts among rights holders.
Faster adoption of new technologies: Improves access to essential patents in complex fields.
Patent pools are especially valuable in industries that rely on many overlapping patents, such as digital communications, semiconductors, or medical devices.
Pro tip: Patent pools work best when the technologies are complementary and the licensing terms are transparent to all participants.
8.3. When should you sell or abandon a patent?
No patent lasts forever. Market conditions change, products evolve, and patent renewal fees add up so companies must regularly decide which patents to keep, sell, or abandon.
Selling a patent can be a smart move when:
The technology no longer aligns with your business strategy.
The patent has greater value in another company’s hands.
You want to generate immediate capital from your IP.
Patent sales often take place through auctions, brokers, or direct negotiations, and buyers may include competitors, startups, or firms expanding their freedom to operate.
The patent no longer supports core business goals.
The protected technology has little commercial potential left.
Keep in mind: in many jurisdictions, you have a grace period to reinstate a lapsed patent, but once that window closes, the protection is lost permanently.
Best practice: Conduct an IP portfolio review at least once a year to evaluate strategic fit, cost efficiency, and market potential. This helps you decide which patents to maintain, sell, or let lapse ensuring your resources focus on the assets that deliver the most value.
8.4. How do you determine the value of a patent?
Patents aren’t just legal protections, they're also valuable business assets. Patent valuation means estimating what a patent is worth by looking at both its commercial and strategic potential.
Key factors in valuation:
Market potential: Demand for the technology and its applications.
Licensing opportunities: Revenue it could generate through deals.
Legal strength: How defensible the claims are against challenges.
Strategic importance: How it supports your broader IP and business goals.
Why patent valuation matters:
Builds credibility with investors and partners.
Informs licensing fee negotiations.
Supports mergers, acquisitions, and fundraising.
Common patent valuation approaches:
Cost-based: Reflects R&D and filing expenses.
Market-based: Benchmarks against comparable patent sales or licenses.
Income-based: Forecasts the future revenue stream from the patent.
There’s no one-size-fits-all method. The most reliable valuations combine market analysis, legal review, and financial modeling to reflect the patent’s true business impact.
9. What does the future of patents look like?
The world of patents is moving faster than ever. Artificial intelligence, big data, and changing global regulations are reshaping how inventions are protected, enforced, and valued. In the near future, we’ll see shorter timelines, more automated processes, and new challenges around ownership and ethics.
Rather than replacing human expertise, these changes will amplify it, giving inventors, attorneys, and businesses the tools to make smarter, faster, and more strategic decisions.
9.1. How is big data changing patent management
Patents are not just legal rights, they are data points in an enormous, constantly growing network of technical and legal information. Every filing, grant, opposition, and patent renewal adds to this global knowledge base.
The challenge for IP teams is not finding the data, but making it useful. That’s where big data patent analytics comes in:
Smarter prior art searches: AI-powered platforms can sift through millions of documents worldwide in seconds, spotting connections that traditional keyword searches might miss.
Portfolio optimization: Advanced analytics highlight which patents generate the most value, which are underperforming, and where there’s room for strategic expansion.
Market forecasting: Tracking filing trends in specific industries can reveal where technology is heading before competitors get there.
Risk assessment: Early detection of potential infringements or overlaps helps avoid costly litigation.
Why big data in IP matters:
Big data makes patent strategy more proactive, turning IP from a defensive asset into a competitive growth driver.
9.2. How is artificial intelligence used in patent applications
Fast prior art search: AI tools scan international databases, filtering by legal status, assignee, and claim language with far greater precision than manual searches.
AI-assisted drafting: From suggesting claim language to generating compliant technical descriptions, these tools help inventors and attorneys produce stronger applications in less time.
Patentability checks: Some AI platforms compare your invention to existing filings and estimate your chances of grant before you even file.
In practice: Patent offices like the EPO and USPTO are experimenting with AI-assisted examination, allowing examiners to handle growing workloads without compromising quality.
Even if AI helps shape an invention, current rules require a human inventor to be named. The legal system has yet to fully catch up to AI-assisted innovation.
9.3. How does AI help manage patent portfolios more effectively
AI is no longer just helping with filing, now AI is streamlining IP management across IP renewals, monitoring, and portfolio decisions with:
Automated IP renewal tracking: AI systems monitor due dates worldwide, adjusting for weekends, public holidays, and time zones.
Portfolio health analysis: AI can flag underused assets, identify patents with licensing potential, and recommend which to keep, sell, or abandon.
Competitor intelligence: Real-time monitoring of new filings in specific markets or technology areas, so you’re never caught off guard.
The advantage: This frees IP teams from repetitive admin work, allowing them to focus on strategic decision-making.
9.4. What will patents look like in the next 5 to 10 years?
If current trends continue, several changes are likely to shape the patent landscape in the coming decade:
Fully integrated AI–IP ecosystems: Drafting, filing, examination, and patent renewal will become part of a single, automated workflow.
Predictive patent strategy: AI models will help determine not only where to file but also which types of claims to pursue based on emerging market data.
Greater transparency in IP renewals: Real-time, publicly accessible databases could make global maintenance status visible, reducing the risk of accidental lapses.
Evolving legal frameworks: Laws are expected to clarify how AI-generated inventions are treated, with possible adjustments to the definition of “inventor.”
More collaborative innovation: With advanced tools lowering barriers to entry, smaller companies and research teams will be better positioned to compete with larger corporations.
The future of patents will be faster, smarter, and more connected. AI will likely become as common in IP management as word processors or CAD software are today. But human expertise will remain essential and the real advantage will go to those who combine data-driven insights with creative, forward-looking strategy.
