Gerolymatos International is a Greek pharmaceutical company focused on developing and commercializing OTC and consumer health products across Europe and beyond.

In this customer story, we spoke with Kostas Alevizopoulos, Chief Scientific Officer. With a strong background in IP and patent law, he oversees R&D and is directly responsible for managing the company’s patent portfolio, including annuity payments and attorney coordination.

Manual processes, rising costs, and timely admin

Before switching to PatentRenewal.com, Gerolymatos International managed patent renewals through their external patent law firm. While the setup worked well during prosecution, it became less practical and much more expensive, once the portfolio matured.

Patent renewals were handled manually via Excel spreadsheets, and fees were broken down in long, complex PDFs. Everything was invoiced in GBP, even though most patents were held in euros, making reconciliation more difficult for internal accounting.

Kostas shared some of the key challenges he faced:

  • Significant cost overhead: Law firm and agent fees created a high annual renewal budget that kept growing.
  • Currency misalignment: Managing payments in pounds for a euro-heavy portfolio complicated internal workflows.
  • Manual invoice matching: Extra time was needed each year to reconcile invoices and explain variances to the accounting team.‍
  • Limited visibility: It wasn’t always clear why certain countries were billed, or not, without going back and forth over email.

“I was spending more time than I should just trying to explain fees and match payments. The setup worked, but the cost was significant, and growing.”

A timely switch to a modern, transparent IP provider

As the portfolio matured, the growing patent renewal costs became harder to justify. After reviewing projected renewal costs for the year ahead, Kostas realised the budget impact was too high to ignore. He began exploring alternatives, and a detailed side-by-side price comparison using their own portfolio data quickly made the choice clear. The savings were substantial, and the service felt straightforward and reliable.


Key reasons for switching to PatentRenewal.com:

  • Clear savings: By eliminating unnecessary agent fees, they cut costs by an estimated 30%.
  • A simpler, online platform: No more tracking Excel sheets or waiting for PDF breakdowns, everything is visible in real time.
  • Fast, friendly communication: The team was responsive and knowledgeable from the very first conversation.‍

No more middle layers: Patent renewals could be managed directly, without multiple intermediaries adding extra fees or delays.

“You could just see the difference right away. The costs were much lower, the setup was simpler, and everything was easier to follow.”

Greater control, less admin, and measurable savings

Switching to PatentRenewal.com gave Kostas and his team full visibility into their IP portfolio without the usual overhead. The impact was clear:

  • Far less admin work and fewer emails
"I don’t need to go back and forth over email anymore. I can just log in, check the status, and move on."
  • Real-time visibility into deadlines and costs
"If something looks off, I can check the platform in 30 seconds and know exactly what’s going on."
  • Smooth handover and clear documentation
"It’s all there, every national application, every detail. Easy to use and saves time."

“It’s a good service. You save money, it’s easier to manage, and it takes less time. For me, it’s a no-brainer.”
