Can Patents Be Renewed? A Comprehensive Guide

The Lifespan of a Patent: Utility, Design, and Plant Patents

The duration of different types of patents:

• Utility Patents: These are the most common types of patents, covering inventions related to processes, machines, or compositions of matter. In the U.S., it has a lifespan of 20 years from the filing date. However, to maintain protection, the original patent holder must pay maintenance fees at regular intervals. Failure to pay these fees can result in the patent expiring earlier.
• Design Patents: These cover the ornamental design of an article rather than its functional aspects. It last 15 years from the date of grant, without the need for ongoing financial maintenance.
• Plant Patents: Granted for new varieties of plants produced through asexual reproduction, plant patents also last for 20 years from the filing date, similar to utility patents, but without any maintenance fee requirements.

Each of these patents provides protection for a set period.

Here’s a quick look:

Type of Patent	What It Covers	Duration
Utility Patent	New processes, machines, or improvements	Up to 20 years
Design Patent	Original and ornamental designs for manufactured items	Up to 15 years
Plant Patent	New varieties of asexually reproduced plants	Up to 20 years

However, the question remains—what happens when these time limits are reached?

Once the protection expires, the invention or design is free for public use unless certain actions are taken to extend the protection or maintain its enforceability.

Why Patents Expire?

Patents have a fixed lifespan, which means they are destined to expire at some point. This expiration is by design, built into the concept of patent law for a few key reasons:

Encouraging Innovation

The expiration of this intellectual property rights encourages original innovation by allowing others to build upon existing inventions. If patents were perpetual, inventors might be less inclined to create new and improved versions of existing inventions.

Promoting Competition

Its expiration promotes competition by allowing competitors to enter the market, driving down prices, and increasing consumer choice.

Rewarding Inventors

The limited lifespan of this monopoly right ensures that inventors are rewarded for their work, but not indefinitely. This encourages inventors to continue innovating and creating new inventions.

Public Domain

When a patent expires, the invention enters the public domain, allowing anyone to use, modify, and improve it without needing permission or paying royalties.

Balancing Interests

Its expiration balances the interests of inventors, competitors, and the public by providing a limited monopoly to inventors while promoting innovation, competition, and the public good.

Can Patents Be Renewed?

In general, patents cannot be renewed in the classical sense. Once this IP rights expires, it cannot be extended or renewed. However, to maintain the validity of it during its lifetime, patent holders must pay annual renewal fees, also known as maintenance fees.

Maintaining a Patent in India

As explicitly mentioned in Rule 80, Section 53 of the Indian Patents Act:

To keep a patent in force, the renewal fees specified in the First Schedule shall be payable at the expiration of the second year from the date of the patent or of any succeeding year and the same shall be remitted to the patent office before the expiration or the second or the succeeding year.

By completely paying a small cost to Patent Renewal Fees throughout the duration of this IP rights, which is 20 years, an individual can have their patent renewed.

Exceptions and Alternatives

There are some exceptions and alternatives:

Patent Term Adjustment (PTA): In the United States PTA allows for the extension of a patent term under certain circumstances, such as delays in the patent office or interference proceedings. However, this is not a renewal, but rather an adjustment to the original patent term.

Patent Term Extension (PTE): In some countries, such as the United States, PTE is available for certain types of patents, such as pharmaceutical patents. This allows for a limited extension of the patent term, usually up to five years.

Continuation Patents: In some cases, inventors can file continuation licenses, which allow them to pursue additional claims or improvements to their original invention. However, this is not an extension of the original monopoly right, but rather a new patent application.

Reissue Patents: In the United States, reissue licenses allow inventors to correct errors or deficiencies in their original monopoly right. However, this is not a renewal, but rather a new legal protection that replaces the original.

Alternatives to Patent Renewal

While patents cannot be renewed once they expire, several alternative strategies can help inventors and businesses extend the protection or commercial advantage of their intellectual property:

Trade Secrets: If an invention can be kept confidential, it can be protected as a trade secret, offering indefinite protection as long as secrecy is maintained.

Unlike patents, trade secrets don’t require registration, but enforcing them legally can be challenging, especially if the secret is disclosed or reverse-engineered.

Copyrights: For works like literary, dramatic, artistic, or musical creations, copyright provide protection for a longer duration than patents. In most countries, copyrights last for the creator’s lifetime plus 50 to 70 years, offering long-term control over the creative work.

Trademarks: A trademark protects brand names, logos, or slogans, offering potentially indefinite protection as long as the trademark is actively used and renewed periodically. This can help businesses maintain their brand identity and prevent others from using similar marks.

New Patents: Inventors can file for new patents on modifications or improvements to the original invention, effectively extending the exclusive rights over the innovation. This strategy, known as “evergreening,” is often used in industries like pharmaceuticals to prolong market control.

When to Renew a Patent?

For utility patents, inventors are required to pay maintenance fees to keep this IP rights active throughout its 20-year lifespan.

These fees are due at regular intervals (3.5, 7.5, and 11.5 years after the patent is granted). These fees ensure this IP remains in force for up to 20 years from the filing date.

• On Time: To keep this IP in good standing, fees should be paid on or before the due date. Paying on time ensures continued protection and prevents any risk of the IP lapsing.
• Early Payment: IP holders can pay their fees early if they wish to avoid missing deadlines. The USPTO allows early payment within six months before the due date. Early payment provides peace of mind, ensuring the patent remains active without last-minute concerns.
• Late Payment: If fees aren’t paid by the due date, there’s a six-month grace period window during which the patent owner can still pay, but with an added late fee. If the fees are not paid during this period, this IP will expire, and the exclusive rights are lost.

Failure to pay these fees results in the patent expiring prematurely.

Fee Due	Timing	Consequence of Non-Payment
First Maintenance Fee	3.5 years from grant date	Patent expires if fee not paid
Second Maintenance Fee	7.5 years from grant date	Patent expires if fee not paid
Third Maintenance Fee	11.5 years from grant date	Patent expires if fee not paid

This is often confused with “renewal,” but it’s more about keeping a patent in good standing during its standard term rather than extending it beyond its original expiration.

How to Pay Patent Renewal Fees?

To maintain the validity of a patent in India, rights holders must pay annual renewal fees. The renewal fee can be paid in advance for the next year before the expiration of the current year.

For example, the renewal fee for the 5th year can be paid before the expiration of the 4th year from the date of the patent.

Payment Timeline

• If the patent is granted within two years from the date of filing, the renewal fee can be paid in advance for the next year.
• If the patent is granted later than two years from the date of filing, the renewal fee that becomes due in the meantime must be paid within three months from the date of recording of the patent in the IP register, or within the extended period not later than nine months from the date of such recording.

Payment Requirements

• The patentee must correctly quote the patent number, date of patent, and the year in respect of which the renewal fee is being paid, in the renewal payment request.
• The payment can be made for 2 or more years in advance, as per the Indian Patents Act.

Extension of Time

An extension of time can be filed under Section 142(4) in the prescribed form along with the prescribed official fees.

Common Mistakes to Avoid When Renewing a Payment?

Renewing a patent is essential for maintaining its patent rights, but several common mistakes can jeopardize this process. Here are key errors to avoid:

Missing Deadlines: Failing to make a timely payment for the payment of maintenance fees is a frequent mistake. In many jurisdictions, including the U.S., these fees must be paid at set intervals (e.g., 3.5, 7.5, and 11.5 years for utility patents). Missing the payment window can result in an expired patent, causing the loss of exclusive patent rights.

Incorrect Payment Amounts: Paying the wrong fee can delay the renewal process. The amount varies based on the entity size (small, micro, or large) and the renewal year. Always verify the correct fee for your classification to avoid issues with intellectual property laws.

Failing to Use the Correct Form: Patent offices often require specific details for renewal, such as the patent number, renewal year, and payment method. Whether using online payment or traditional methods, ensure forms are completed accurately to protect your intellectual property assets.

Not Taking Advantage of Grace Periods: If a deadline is missed, some jurisdictions offer a grace period with penalties. Failure to pay within this period of time may result in a permanent loss of intellectual property rights.

Overlooking International Patents: For global intellectual property matters, manage different renewal schedules to prevent lapses in various jurisdictions.

Carefully managing renewals ensures your intellectual property assets remain protected.

What Should an Expired Patent Holder Consider?

If a patent has expired, the patent holder should consider the economic impacts on their business and take necessary steps to mitigate any negative effects.

Economic Impacts

Loss of exclusivity: The patent holder can no longer prevent others from making, using, or selling the invention.

Decreased revenue: The expiration of the patent may lead to a decrease in revenue as competitors enter the market.

Changes in market dynamics: The patent holder may need to adapt to new market conditions and adjust their business strategy.

Increase Marketing Efforts

Focus on branding: Emphasise the brand and its reputation to differentiate from competitors.

Highlight unique selling points: Identify and promote the unique features and benefits of the product or service.

Develop new products or services: Invest in research and development to create new products or services that can be patented or protected by other intellectual property rights.

Other Options

Restoration of lapsed patents: If the failure to pay the renewal fee was unintentional, the patent holder may be able to restore the patent.

Reissue patents: In some cases, inventors can file reissue patents to correct errors or deficiencies in their original patent.

Continuation patents: Inventors can file continuation patents to pursue additional claims or improvements to their original invention.

It is essential for the patent holder to carefully consider these options and seek professional advice to determine the best course of action for their specific situation.

What’s Next?

While patents cannot be renewed, there are essential strategies for intellectual property owners to manage their rights as their patent term approaches.

In fast-growing markets, the degree of market exclusivity provided by a patent plays a key role in determining market opportunities. Ensuring compliance with legal requirements, such as periodic patent maintenance fees and making accurate payments, is critical to retaining protection.

Managing intellectual property involves knowing the complex processes involved in paying maintenance fees and using the right payment tool. Missing a maintenance fee payment could lead to the loss of licensing agreements or market dominance.

Conducting a patent search to track your competitors and staying informed about legal issues is equally important.

The availability of resources and the proper development of ideas are also key factors in keeping inventions valuable. Maintaining your patent ensures the period of protection may last its full term, allowing you to maximise your intellectual property’s potential.
