Patent Renewal in India

Views: 0

Introduction

A patent grant is not the end of the process of maintaining patent protection. It is, in an important sense, the beginning of a new set of obligations. Unlike trademark registration, which is renewed every ten years through a single renewal application, or copyright protection, which requires no renewal at all, a patent in India must be actively maintained through annual renewal fee payments every year from the third year of the patent’s life until either the patent expires at the end of its twenty-year term or the patentee decides to let it lapse.

Missing a renewal fee payment is not a minor administrative oversight with a manageable fix. It results in the patent lapsing, which means the invention falls into the public domain and can be used, manufactured, and sold by any third party without the former patent holder’s permission. While the Indian patent system provides a limited restoration mechanism for lapsed patents, the process is discretionary, requires specific grounds, and is not available beyond a certain period. The most reliable approach to maintaining patent protection is to never miss a renewal payment in the first place.

For businesses and individual inventors who have invested the time, money, and effort to obtain a patent, understanding the renewal fee structure, the payment deadlines, the procedures for restoration if a payment is missed, and the practical systems that ensure no renewal falls through the cracks is as important as understanding the original grant process.

This guide is written for patent holders, R&D managers, IP portfolio managers, licensing executives, technology transfer offices, and legal practitioners who need a comprehensive understanding of the patent renewal framework in India. It covers the legal basis for renewal fees, the fee amounts for different categories of applicant, the payment schedule and deadlines, the consequences of non-payment, the restoration process, and the practical management systems that keep a patent portfolio in good standing.

For patent renewal management and complete IP portfolio support, the IP team at Quick Startup India works with patent holders across all technology sectors.

The Legal Framework for Patent Renewal in India

Patent renewal in India is governed by the Patents Act, 1970 and the Patents Rules, 2003 as amended. The key statutory provisions are:

Section 53 of the Patents Act establishes that a patent remains in force for twenty years from the date of filing the application, subject to payment of renewal fees. The section specifies that the renewal fees prescribed in the Second Schedule must be paid to keep the patent in force.

Section 60 of the Patents Act governs the restoration of lapsed patents, providing a mechanism to revive a patent that has lapsed due to non-payment of renewal fees, subject to conditions and time limits.

Rule 80 of the Patents Rules, 2003 specifies the procedures for payment of renewal fees, including the timeline for payment and the surcharge applicable for late payments.

The Second Schedule to the Patents Act sets out the fee amounts for renewal (referred to as fees for extension of time, or renewal fees) for different categories of applicants and for each year of the patent’s term.

When Renewal Fees Become Payable

The Starting Year

Renewal fees in India are payable from the second year of the patent’s term. The first year is treated as covered by the initial application fee. This means the first renewal fee falls due for the period covering the third year of the patent, payable in advance during the second year.

In practical terms:

• Year 1: No renewal fee due.
• Year 2: First renewal fee payable (covering the third year).
• Year 3: Second renewal fee payable (covering the fourth year).
• This continues annually until the twentieth year.

For a patent filed on 15 March 2020, the first renewal fee would fall due on or before 15 March 2022 (paying for the third year, covering 15 March 2022 to 15 March 2023).

The Payment Window

Each annual renewal fee is payable before the expiry of the year it covers. The Patents Rules provide that the renewal fee may be paid at any time during the year for which it is due, and also that a renewal fee due on a date that has already passed at the time the patent is granted can be paid within three months of the date of the grant.

This three-month grace period after grant is particularly important for patents where the grant takes several years from the filing date. If a patent is filed in 2020 and granted in 2025, several years’ renewal fees will already have been due. The patentee has three months from the date of grant to pay all outstanding renewal fees for years already elapsed, without any surcharge.

Late Payment With Surcharge

If a renewal fee is not paid by the due date but is paid within six months of the due date, the Patents Rules allow late payment with an additional surcharge. The surcharge for late payment is prescribed in the Patents Rules and varies depending on the category of applicant.

This six-month surcharge window is not a grace period to be relied upon as a matter of course. It is a safety net for genuinely accidental delays, not a routine extension of the payment deadline.

Lapsing After the Surcharge Period

If the renewal fee is not paid within the six-month surcharge period, the patent lapses. The lapse takes effect from the date the renewal fee was originally due, not from the end of the surcharge period. This means that the patent is treated as having been unprotected from the original due date of the unpaid renewal fee.

Renewal Fee Amounts: The Category System

The Patents Act and the Second Schedule distinguish between different categories of applicants, with significantly different fee amounts applicable to each. This tiered structure is designed to make the patent system accessible to individual inventors, small entities, and research institutions while charging higher fees to larger commercial entities.

Natural Persons (Individual Inventors)

A natural person is an individual human being. For a patent filed by and held by one or more natural persons, the reduced individual renewal fee schedule applies. This is the lowest fee tier.

Startups

Startups recognised under the DPIIT Startup India programme are entitled to reduced fees at the same level as natural persons (individual inventors) for the purposes of patent filings and renewal. This benefit makes patent maintenance significantly more affordable for early-stage technology companies.

Small Entities

A small entity is a business entity that qualifies as a small enterprise under the MSME Act. Small entities are entitled to a reduced fee schedule, higher than the individual rate but significantly lower than the standard fee.

Other Applicants (Companies, Large Entities, Foreign Entities)

All applicants who do not qualify as natural persons, startups, or small entities pay the standard renewal fee schedule. This includes private limited companies, public limited companies, large enterprises, and foreign entities. The standard fee is significantly higher than the reduced rates applicable to individuals and small entities.

Current Renewal Fee Schedule

The following fee amounts are prescribed in the Second Schedule to the Patents Act as of 2026. These fees are subject to revision through gazette notification and should be verified on the Indian Patent Office website (ipindia.gov.in) before making any payment.

Physical filing fees (submitting the renewal request in person at the Patent Office) are ten percent higher than e-filing fees. E-filing is strongly recommended both for the cost saving and for the administrative convenience of maintaining a digital record of each payment.

Total Renewal Cost Over the Patent’s Life

Adding the renewal fees across all eighteen payable years (years 3 through 20) gives a sense of the total maintenance cost over the patent’s life:

For a natural person or startup, the total renewal fee cost over the full twenty-year term is approximately Rs. 30,800 (e-filing rates). For a company, the total is approximately Rs. 154,000 (e-filing rates). These amounts should be factored into the commercial assessment of whether maintaining a patent to the full term is justified, particularly for patents in technology areas where the commercial relevance of the invention may diminish before the twenty-year term expires.

The Renewal Payment Process: Step by Step

Step 1: Identify the Renewal Due Date

The renewal due date for each year is the anniversary of the patent’s filing date. For a patent filed on 10 June 2018, every renewal is due on 10 June of each subsequent year. The filing date, not the grant date, is the anchor for the renewal schedule.

Step 2: Determine the Correct Fee

Identify the correct fee category applicable to the patent holder (natural person, startup, small entity, or other) and the year for which the renewal is being paid. Both of these factors must be correct for the payment to be valid.

If the category of the patent holder has changed since the original application (for example, a natural person who has since incorporated a company), the current entity status at the time of renewal determines the applicable fee category.

Step 3: Access the Patent Office Portal

Renewal fees are paid online through the Indian Patent Office portal at ipindia.gov.in. The portal provides access to patent-specific services including renewal fee payment under the section for patents.

Step 4: File Form 4

The renewal fee is submitted through Form 4 (Request for Extension of Patent), completed and submitted through the online portal. The form requires:

• The patent number.
• The year or years for which renewal is being paid.
• The category of the patent holder.
• The fee amount.
• Payment details.

Multiple years can be paid simultaneously if the patent holder wishes to pay in advance or to catch up on multiple outstanding years.

Step 5: Make the Payment

Payment is made online through the portal using net banking, credit card, or debit card. The portal generates a receipt confirming the payment which should be downloaded and retained.

Step 6: Retain the Payment Record

Maintain a secure record of every renewal payment: the Form 4 submission, the payment receipt, the patent number, the year paid, and the date of payment. This documentation is essential if any dispute arises about whether a renewal was timely paid.

Advance Payment of Renewal Fees

The Patents Rules permit patent holders to pay renewal fees in advance for multiple future years simultaneously. Advance payment has several practical advantages:

Administrative efficiency. Paying several years at once reduces the number of annual transactions and the administrative overhead of managing individual annual payments.

Fee stability. Patent renewal fees have increased periodically through gazette notifications. Paying in advance at current rates locks in the current fee structure for those years.

Risk reduction. Paying several years in advance eliminates the risk that a specific annual deadline is missed due to administrative oversight, portfolio changes, or personnel transitions in the IP management team.

The Patent Office accepts advance payments and the payment records are maintained against the specific patent. There is no cap on how far in advance renewal fees can be paid.

Consequences of Non-Payment: Patent Lapsing

When a renewal fee is not paid within the prescribed due date and the six-month surcharge period, the patent lapses automatically by operation of law. No formal cancellation order is required; the lapse occurs automatically when the deadline passes without payment.

Immediate Consequences of Lapsing

• The patent is no longer in force and provides no protection.
• The invention described in the patent enters the public domain.
• Any person can manufacture, use, sell, or import the formerly patented invention without the ex-patent-holder’s permission.
• Any ongoing licensing agreements based on the patent become affected; licensees may argue that the licence has terminated or that the royalties owed are reduced or eliminated.
• The ex-patent-holder cannot assert infringement claims for acts occurring after the lapse date.

The Public Domain Effect

Once a patent lapses and the invention enters the public domain, this cannot be reversed. Even if the patent is subsequently restored through the restoration process, the period of lapse during which the invention was in the public domain means that acts of manufacture, use, or sale during that period cannot be pursued as infringement.

Restoration of a Lapsed Patent: Section 60

Section 60 of the Patents Act provides a mechanism to restore a patent that has lapsed due to non-payment of renewal fees, subject to specific conditions and time limits.

The Restoration Application

An application for restoration of a lapsed patent must be filed within eighteen months from the date on which the patent lapsed. This is the absolute deadline; no application for restoration can be accepted after this period expires.

The restoration application is made in Form 15 and must be accompanied by:

• A statement of the reasons for the failure to pay the renewal fee.
• Evidence supporting those reasons.
• The unpaid renewal fee.
• The restoration fee prescribed in the First Schedule.

Grounds for Restoration

The Registrar of Patents may restore the patent if satisfied that the failure to pay the renewal fee was unintentional and that there has been no undue delay in making the application for restoration. Both conditions must be met:

Unintentional failure. The Registrar considers whether the failure was a genuine accidental oversight rather than a deliberate decision not to renew. An administrative error, a communication failure with a patent attorney, or an internal oversight can all support an unintentional failure. A deliberate decision not to renew the patent (for example, to save money) followed by a change of mind does not support unintentional failure.

No undue delay. The application must be made promptly after the lapse is discovered. A patent holder who discovers the lapse but waits several months before filing the restoration application may face rejection on the ground of undue delay.

Consequences of Restoration: Third-Party Protections

If a patent is restored, the Patents Act protects third parties who, during the period when the patent was lapsed, made or used the invention in good faith. Such third parties may continue to use the invention, or to use or sell specific articles manufactured during the lapse period, without constituting infringement of the restored patent.

This third-party protection significantly reduces the commercial value of a restored patent compared to a patent that never lapsed: any competitors or third parties who began using the invention during the lapse period can continue to do so.

Application and Examination

After the restoration application is filed, the Patent Office publishes notice of the application, inviting opposition from any person who would be prejudiced by the restoration. If no opposition is filed, or if any opposition is dismissed, the patent is restored to force from the date of lapse and the patentee receives confirmation of restoration.

Patent Renewal Management: Practical Systems

For businesses with multiple patents or pending applications, managing renewal deadlines is a portfolio management function that requires systematic attention. The consequences of missing renewals, and the limited and uncertain restoration remedy, make proactive management essential.

Patent Portfolio Register

Maintain a comprehensive register of all patents and applications, with the following information for each:

• Patent or application number.
• Title of the invention.
• Filing date (the anchor for all renewal due dates).
• Grant date.
• Category of applicant (natural person, startup, small entity, other).
• Current renewal year and the next renewal due date.
• Status: active, lapsed, abandoned, or licensed.
• Any encumbrances: licences, assignments, pledges.

This register should be reviewed and updated regularly and should be accessible to at least two people in the organisation.

Automated Calendar Reminders

Set automated calendar reminders at multiple intervals before each renewal due date: six months before, three months before, one month before, and one week before. Multiple reminders ensure that even if the earliest reminder is missed or action is deferred, there are subsequent opportunities to act before the deadline.

Dedicated IP Management Software

For larger patent portfolios, dedicated IP management software automates the tracking of renewal deadlines, generates payment reminders, and maintains a history of all renewal payments. Several platforms are available that integrate with patent databases to pull renewal deadline information directly.

External Annuity Management Services

Many patent holders engage specialist patent renewal (annuity) services to manage all renewal payments on their behalf. These services track every patent in the portfolio, calculate the correct fee for each due date, and make payments automatically, providing confirmation receipts and portfolio reports. The cost of these services is typically modest relative to the risk of a missed renewal.

Engagement of Patent Attorneys

Patent attorneys engaged to manage the prosecution of a patent application can also be engaged for ongoing renewal management. A law firm or patent agent firm with a robust docket management system typically handles renewal payments as part of their patent portfolio management service.

Strategic Decisions About Patent Renewal

Not every patent in a portfolio is worth maintaining to its full twenty-year term. For businesses with growing patent portfolios, making strategic decisions about which patents to renew and which to allow to lapse saves renewal fee expenditure without compromising the commercially significant patents.

Assessing Renewal Value

For each patent approaching a renewal due date, a brief commercial assessment considers:

Is the patented technology still being used? A patent protecting a technology that has been superseded or abandoned commercially may not justify continued renewal fees, particularly at the higher rates applicable in later years.

Is the patent being licensed? A patent generating royalty income should be renewed for as long as the licence agreement is in force and the royalty income justifies the renewal cost.

Does the patent provide a defensive value? Even patents that are not actively enforced or licensed may have defensive value in preventing competitors from patenting similar subject matter or in providing cross-licensing leverage in patent negotiations.

Is the technology area still relevant? In rapidly evolving technology sectors, a patent filed ten years ago may no longer reflect the cutting edge of the technology, reducing its value for both offensive and defensive purposes.

What is the remaining term relative to the commercial lifecycle? A patent with three years remaining and a technology that has an additional five years of commercial relevance should be renewed. A patent with twelve years remaining on a technology that has already been superseded by newer innovation may not warrant continued investment.

Documenting the Abandonment Decision

When a deliberate decision is made to allow a patent to lapse by not paying a renewal fee, that decision should be formally documented in the portfolio management record. A deliberate, documented abandonment decision is different from an accidental lapse and ensures that the organisation’s patent strategy records are accurate.

PCT Patents and International Renewal

For patent applications filed through the Patent Cooperation Treaty that have entered the national phase in India, the Indian renewal fee obligations apply from the date of the PCT application (the international filing date), not from the date of national phase entry. This means that renewal fees for years already elapsed by the time of national phase entry must be paid within a specified period after national phase entry, similar to the three-month window after grant for domestically filed patents.

For Indian applicants who have also obtained patents in other jurisdictions through the PCT, each country has its own renewal fee structure and deadlines. Managing an international patent portfolio requires either jurisdiction-by-jurisdiction tracking or the engagement of a specialised annuity management service that covers multiple jurisdictions.

Patent Renewal vs. Trademark Renewal: Key Differences

Patent renewal and trademark renewal share the feature of requiring active payment to maintain the registration, but they differ in several important ways:

This comparison underscores the different nature of patent and trademark protection. A trademark can theoretically be maintained forever, reflecting a brand that can grow in value indefinitely. A patent is inherently time-limited, reflecting a policy balance between rewarding innovation and ensuring that knowledge eventually enters the public domain.

Frequently Asked Questions

Conclusion

Patent renewal is the ongoing obligation that keeps a granted patent alive and commercially effective throughout its twenty-year term. Unlike a one-time grant that persists without further action, a patent must be actively maintained through annual fee payments from the third year onwards, with fees that increase in the later years of the patent’s life and that vary significantly based on the category of the patent holder.

The consequences of missing renewal payments, the limited and conditional restoration remedy, and the irreversibility of allowing a commercially significant patent to enter the public domain make proactive, systematic renewal management as important as the original prosecution strategy. A patent that is allowed to lapse due to an administrative oversight is a patent that has lost its commercial value permanently, regardless of how much was invested in obtaining it.

The practical systems that prevent this outcome are not complex: a comprehensive patent portfolio register, automated deadline reminders, advance fee payments where appropriate, and the engagement of professional renewal management services for portfolios of meaningful size. These systems cost a fraction of the value of the patents they protect.

Pay on time, every time. Use advance payments to reduce administrative risk. Monitor your portfolio proactively. And treat patent renewal as the business priority it is.
