Understanding the key differences in global patent renewal laws

Navigating IP management on a global scale requires an understanding of how patent renewal laws vary across jurisdictions. While global treaties offer frameworks for initial filings, countries retain unique laws, impacting patent renewal schedules, documentation requirements, and penalties. 

This article explores some major differences in patent renewal laws around the world, based on our most up-to-date knowledge as of November 2024, reflecting current insights. Our blog post highlights a few key regions, challenges faced by IP holders, and expert insights to help patentees make informed IP renewal decisions.

Key differences in patent renewal requirements across regions
‍

Patent renewal timelines and requirements differ widely by country, impacting how IP holders manage their assets. For instance, in the European Union, the United States, Japan, and China each enforce distinct renewal timelines, grace periods, and fees, impacting how patentees approach long-term patent maintenance: 

• European Union: The European Patent Convention (EPC) provides a 20-year patent term, with annual renewal fees required both before and after the patent grant. For European Patent (EP) applications, patentees pay annual fees directly to the EPO. After the EPO grants the application, patentees must pay annual renewals in the chosen validation countries or continue with a single payment to the EPO if they select the Unitary Patent (UP) system. 
• United States: U.S. patents also last 20 years, and patent maintenance fees are due three times over the patent term: at 3.5, 7.5, and 11.5 years from issuance. Unlike Europe’s annual payment model, this schedule gives patentees longer intervals between fees. 
• Japan: Japanese patent laws require annual renewal payments beginning from the fourth year of the grant, with patent renewal fees increasing annually. Annuities for the first three years are paid upon grant, and the next is due in the fourth year after grant. 
• China: Patents in China have annual patent renewal requirements from the first year post-grant, but the annuity timeline is calculated from the original filing date. China’s patent maintenance system is more rigorous for patents in high-volume sectors, such as technology, where non-compliance risks costly lapses in a rapidly expanding market​.

Each of these systems emphasizes the importance of strategic patent maintenance, especially for patentees holding portfolios across different jurisdictions.

Penalties and grace periods for late patent renewals
‍

Grace periods and penalties affect where and how companies choose to maintain patents. Jurisdictions with steep penalties for late patent maintenance may influence a company’s decision to renew strategically valuable patents only. 
‍

“In countries with severe penalties for missed renewals, firms need to allocate resources to ensure timely compliance, which might involve hiring legal experts familiar with international patent laws. These differences can also impact decisions on where to file new patents, whether to maintain current patents, and how to prioritize IP portfolios.
Companies may choose to maintain patents longer in jurisdictions with lenient policies, whereas in strict countries, they might opt to let certain patents lapse if they’re not strategically vital. This strategic planning is integral to safeguarding a company’s inventions and innovations globally.” - Rick Chahal ( Licensed Paralegal & Legal Assistant, Marketing expert, Kahlon Law)

In some countries, short or nonexistent grace periods require strict attention to deadlines, while others with extended grace periods provide flexibility, allowing companies more time to respond to administrative or financial hurdles. For example:

• Germany: German law provides a six-month grace period for late payments but with a 50€ additional fee. After this period, patents lapse,  so timely compliance is essential.
• South Korea: South Korea allows a six-month grace period for late payments with an additional fee. However, beyond this period, patentees must submit a “petition for reinstatement,” requiring justification and higher administrative fees​.
• China: Chinese law provides a six-month grace period after each renewal date. If payment isn’t made within this window, the patent lapses. Patentees can request restoration within two months of receiving a lapse notice by providing reasons and paying a restoration fee. In special cases, such as force majeure situations, they may request restoration up to two years from the original payment deadline. This grace period is especially important for high-tech and fast-growing industries, where maintaining IP protection is crucial. 
• Japan: Japan provides a six-month grace period for late payments with a 100% surcharge fee, making compliance critical to avoid high renewal costs.
• United States: In the U.S., a six-month grace period for late payments is available, with a surcharge that varies based on the entity type: $100 for micro-entities, $200 for small entities, and $500 for large entities. After the six-month period, reinstatement may be possible under “unintentional delay” standards, though the process can be resource-intensive but the surcharge fee during this period is set at 50% of the unpaid amount. 

“Some of the regions or countries with strict patent-renewal procedures include Japan, South Korea, and European Union member states. These regions have well-established patent systems in place that prioritize protecting intellectual property rights.
Keep track of all important deadlines and documents related to your patents. It's important to stay organized and on top of the renewal process, especially in these stricter regions. It's also important to carefully review and understand the rules and regulations surrounding patent renewals in each region.
For example, some countries may require additional documentation or fees for late renewals, while others may have strict timelines for submitting renewal applications.” - Keith Sant, (Founder & CEO, Kind House Buyers)

Patent renewals across industries
‍

Beyond timelines and penalties, some countries enforce distinct regulations that can complicate global patent maintenance. 

“One notable trend is the increased stringency in patent renewal compliance in countries like China and India, where patent lapses may directly impact the availability of replacement parts or safety recalls. This can affect personal injury claims related to malfunctioning medical devices or pharmaceuticals. 
We rely on industry reports and legal briefings from specialized patent-law firms to stay informed. By keeping an eye on international patent news through these channels, we ensure we are prepared to handle cases where patent renewals (or the lack thereof) impact product liability in injury cases.” - David E. Preszler (Assistant Lawyer, Preszler Injury Lawyers)
‍

In high-stakes industries like pharmaceuticals and biotechnology, where regulatory approvals often delay commercialization, patentees may prioritize patent maintenance for the entire patent term to maximize market exclusivity.

Additionally, biotech or pharma patents in certain countries may qualify for a Supplementary Protection Certificate (SPC), which can extend the patent’s duration beyond the typical 20 years. This extension compensates for the time lost during lengthy regulatory approval processes, allowing patentees to fully benefit from their innovations. 

In contrast, sectors with faster innovation cycles, such as consumer electronics and luxury goods, often see patents lapse earlier as companies shift focus to newer technologies.

The role of international treaties in patent renewal law
‍

Although renewal processes vary, international treaties provide frameworks that harmonize aspects of patent law and simplify initial filings.

1. Patent Cooperation Treaty: The PCT allows applicants to file patents in multiple countries through a single application, offering uniformity in the initial stages of patent registration. However, patent renewals are governed individually by each country, meaning patentees must still comply with national regulations upon entering the national phase​
2. Unitary Patent System: The European Unitary Patent is designed to streamline patent protection across multiple European countries. While it technically replaces the national patent maintenance requirements entirely for the countries covered by the UP system, it simplifies the process by consolidating renewals into a single payment to the EPO. This unified approach, particularly beneficial in the first decade, reduces the administrative complexity involved in maintaining patent protection across multiple jurisdictions.
3. Paris Convention: The Paris Convention enables a 12-month grace period for filing patents across member countries. This helps IP holders strategize their filings internationally, but it has no effect on patent renewal fees or national compliance, which remain unique to each country​.
