Utility models are a form of intellectual property protection that is often overshadowed by patents but are equally important for inventors, especially for ones focusing on incremental innovations. This article explores the basics of utility models, their qualification criteria, the differences from patents, and their availability across various jurisdictions. Whether you're an inventor, a business owner, or an IP professional, understanding the nature of utility models can be advantageous when protecting and managing your innovations.


Terminology: utility model, petty patent, innovation patent, etc.


Utility models grant exclusive rights to the owner of an invention and offer legal protection to prevent others from commercially using the protected technology. 

As of January 2024, utility models are available in the below mentioned 76 jurisdictions, sometimes also called utility model patents, utility certificates, petty patents, simple patents or innovation patents. Regardless of the name, these intellectual property rights generally offer similar protection, therefore they can be all categorized as utility model rights.

What qualifies for utility model protection


What can be protected by utility models varies by jurisdiction worldwide. In some countries, all patentable technological fields are available for utility model protection as well, but in others, utility model protection is solely available for certain types of technology (like mechanical devices) and only for products, not for processes. In these instances, you can't use a utility model to protect a method or a way of doing something (which is often covered by patents), but only a tangible, physical product.

On the other hand, the requirements for the inventions “inventive step” and “novelty” are often lower when it comes to utility model applications, so inventors often choose this protection for inventions that are not patentable due to the above mentioned criteria, such as more modest improvements or adaptations of technologies.

Obtaining both a patent and a utility model for the same invention is not possible, in case the same inventor would file for both patent and utility model protection for the same technology, either only the earliest application would be valid, or the inventor could choose which one to commence with. In some jurisdictions, converting patent applications into utility model applications, and the other way are both possible.


The renewal and protection of utility models


In most countries, where utility models are available, they generally have a shorter protection span, usually 6 to 10 years, depending on the jurisdiction. The renewal process is more straightforward and less expensive compared to traditional patents. After utility models become granted, they often need to be renewed every year. If the renewal fee is not paid on time, the invention will lose its protection and will be available for public use again.

Comparing patents and utility models 


Utility models and patents both offer exclusive rights to an invention within a country where they are granted. While utility models are sometimes also referred to as “short-term patents” or “innovation patents”, there are key differences between patents and utility models when it comes to costs, duration and the inventions themselves.

Choosing between patents and utility models is a key consideration when an inventor is seeking protection for a newly invented technology or technological improvement.
For better understanding, we summarized the similarities and differences between patents and utility models in 3 aspects: 

  • Coverage of the protection: Both patents and utility models need to be protecting novel inventions, but with utility models, the requirements of novelty might be lower, or only required on a local level, which makes utility models available for a wider range of inventions.
  • Application & fees: Utility models, just like patents, need to be registered through the national patent office. If an inventor would like to apply for a utility model, they need to follow application rules based on each local jurisdiction. Generally, in most countries utility model applications, unlike patent applications, do not go through the same substantive content (like novelty, inventive step, and industrial applicability) examination process before they can be registered, making the application process easier and the examination fee often absent. 
  • Duration and renewal options:  While patents are generally protected for long term, up to 25 years in certain countries, utility models have a shorter life span of usually between 6-10 years depending on the jurisdiction. They need to be renewed every year, but official renewal fees are usually cheaper than patent renewal fees, making them more affordable for inventors.
