Can a Patent be Renewed?

Is your patent nearing its expiration date? This is a pivotal moment, as the end of a patent term impacts your exclusive rights to your invention and raises questions about how to protect your market position. While you may wonder if renewing your patent is possible, the reality is more complex.

Patents in the U.S. aren’t eligible for straightforward renewals. However, specific strategies can extend a patent’s reach in specific cases. With insights from a patent attorney, this guide walks you through the essentials of patent expiration, limitations, and available paths to keep your invention’s value strong.

Patent Overview

Patents are essential tools within intellectual property. They grant inventors exclusive rights to their creations and give them control over who can make, use, or sell their inventions for a limited time.

For a patent to be granted, an invention must meet specific criteria: it must be novel, non-obvious, and useful. These requirements help ensure that patents protect genuine innovations rather than minor improvements or obvious ideas.

Most patents fall into one of three categories:

• Utility Patents: Cover inventions with specific functions, such as machines, processes, or compositions of matter. These are the most common type of patent and last for 20 years from the filing date (plus any potential USPTO delays) (see 35 U.S. Code § 154).
• Design Patents: Protect the unique visual aspects of an object, focusing on appearance rather than function. Design patents last for 15 years from the date of grant. (See 35 U.S. Code § 173.)
• Plant Patents: Apply to new and distinct varieties of asexually reproduced plants. These patents also have a 20-year term from the filing date. (See 35 U.S. Code § 161).

Once a patent is granted, it provides a period of exclusivity that allows inventors to commercialize their creations and hopefully recover their development investments. However, when the patent term expires, the invention enters the public domain, meaning anyone can use, make, or sell it without your permission.

Though patents are not traditionally renewable, some inventions qualify for limited extensions under specific circumstances. This is especially important in sectors like pharmaceuticals, where the time required for regulatory approval can reduce a patent’s lifespan of commercial payback.

When Can You Request a Patent Renewal?

Patent renewals are exceedingly rare and typically granted under exceptional circumstances. These cases often require validation through a special act of Congress and typically involve delays or errors during the U.S. Patent and Trademark Office (USPTO) application process. Below are three key scenarios where a patent renewal might be considered:

1. Delays Caused by the USPTO During Application Review
   In some instances, the USPTO may unnecessarily prolong the approval process of a patent application. Whether due to administrative backlogs or procedural inefficiencies, such delays can shorten the effective lifespan of your patent. If you can provide evidence that your application was unreasonably delayed by the USPTO, you may have grounds to request a renewal to compensate for the lost time. (See U.S. Code § 154(b).)
2. Failure to Make a Timely Determination
   The USPTO is expected to issue a determination within three years of a patent application’s submission. If they fail to do so, it may be considered an unreasonable delay. This wasted time can hinder your ability to fully utilize your patent. Under such circumstances, you may be eligible to apply for a renewal to recover the lost portion of your patent term. This is referred to as a PTA (Patent Term Adjustment) See 35 U.S. Code § 154(b)).
3. Delays Due to Interference Proceedings
   Interference occurs when two inventors file applications for the same invention. While the USPTO is responsible for resolving these disputes, the process can significantly delay the approval of one or both applications. If such interference causes an undue delay that affects your patent’s effective term, you may be eligible for a renewal to account for the lost time. (See U.S. Code § 154(b).)

Patent Expiration and Public Domain Entry

When a patent expires (or becomes abandoned and is not revived), the exclusive rights granted to the inventor end, and the invention enters the public domain. This shift has significant implications for the original inventor, any assignees, and others in the industry.

Once an invention is in the public domain, anyone can use, make, sell, or modify it without seeking permission from the patent holder. This promotes further innovation by allowing others to build upon the invention and make it more accessible.

The patent’s expiration doesn’t mean the invention loses all value; many inventions continue to influence industries and contribute to technological progress. However, the loss of exclusivity means the owner of the patent rights can no longer control how their creation is used. This can impact revenue streams, primarily if the invention was licensed or sold for profit during the patent term.

How Can You Prolong Patent Rights?

While patents have a set term, there are ways to extend your rights under certain conditions. In some cases, inventors can take specific steps to prolong their patents’ effective protection.

Understanding these options is important to maintain control over your invention and maximize its commercial value. Let’s explore the strategies to help you extend your patent’s lifespan.

Patent Term Extensions

Patent Term Extensions (PTE) allow patent holders to extend the term of their patents under specific conditions, primarily when delays in regulatory processes have reduced the patent life. This extension is designed to help patent holders recover time lost due to these unavoidable delays, which is especially important in industries like pharmaceuticals and biotechnology, where regulatory approval can be lengthy and complex.

• Purpose of Patent Term Extensions: The purpose of PTE is to compensate patent holders for time lost during the regulatory approval process, which is often out of their control. In sectors like pharmaceuticals, the time spent waiting for FDA or similar regulatory agency approval can drastically shorten the life of a patent, which is crucial for commercializing the invention. The PTE allows the patent holder to regain some of this time.
• Eligibility for PTE: Typically, only patents covering products that require regulatory approval (such as drugs, medical devices, and agricultural chemicals) are eligible for PTE. The extension is granted for up to five years, but the total patent term, including the extension, cannot exceed 14 years from the date of product approval. Extensions are calculated based on the regulatory delays, with specific requirements to qualify, including the time the regulatory agency took to approve the product.

Patent Term Adjustments

Patent Term Adjustments (PTAs) are designed to compensate for delays during the patent application process. When a patent application takes longer than the statutory deadlines set by the United States Patent and Trademark Office (USPTO) to be examined, the patent holder is entitled to an extension of their patent term.

This adjustment ensures that inventors do not lose valuable time due to the USPTO’s delays. There are several essential aspects to consider regarding Patent Term Adjustments. Here are some essential points to remember that clarify how these adjustments work and how they impact your patent’s duration:

USPTO Delays During Examination

Patent Term Adjustments (PTAs) apply when delays occur during the patent application process, such as when the USPTO takes longer than the prescribed time to review an application or issue office actions.

Automatic Adjustments for Procedural Delays

PTAs are automatically granted when the USPTO fails to meet specific deadlines. These adjustments ensure that applicants are not penalized for the office’s slow pace in processing the patent application.

Maintenance Fees and Adjusted Expiration Dates

Maintenance fees still apply while the patent term is extended due to PTAs. The adjusted expiration date may impact the timing of these fees, which must be paid at specific intervals to keep the patent active. These deadlines occur periodically throughout the life of a patent and are set by the United States Patent and Trademark Office (USPTO).

Why Are Maintenance Fees Essential?

Maintenance fees are designed to help manage the limited resources of the patent office, ensuring that patent holders who still see value in their inventions maintain their protection. In contrast, patents that expire, free up the invention for public use. Here are key points to consider about maintenance fees:

• Fee Schedule and Deadlines: For U.S. utility patents, maintenance fees are typically due 3.5, 7.5, and 11.5 years after the patent is granted. The USPTO sets these intervals to allow patent holders to periodically reevaluate their invention’s commercial value.
• Cost of Maintenance Fees: The fee amount varies, depending on the patent type and the entity’s size (small businesses may pay reduced rates). The costs increase with each interval, encouraging holders to assess whether they wish to continue holding exclusive rights.
• Consequence of Non-Payment: Failure to pay a maintenance fee results in the patent lapsing, meaning the invention becomes part of the public domain and loses legal protections.

Difference from Patent Term Extensions (PTE)

Unlike Patent Term Extensions, which primarily address regulatory delays outside the patent application process, PTAs focus on delays within the patent examination process. Both serve to extend the life of a patent, but they apply under different circumstances.

Guide to Applying for a Patent Term Extension

Applying for a PTE (see U.S. Code 35 U.S.C. § 156) involves meeting regulatory criteria, compiling documentation, and following the detailed application process. Here’s a guide that outlines the basic steps, qualifications, and best practices to increase the likelihood of a successful extension:

1. Verify Eligibility: Confirm that your invention qualifies for a PTE based on regulatory delay requirements, product type, and other specific criteria.
