Renewal Process of an Expired Patent

When a patent is given for an invention in India, the next requisite step is to guarantee that it is renewed annually and unceasingly. Section 53 Rule 80 of the Indian Patents Act talks about the renewal process of an Expired Patent. It can be done by the payment of Patent Renewal Fees diligently during the lifetime of the patent, i.e. 20 years.

Payment and Repayment of Renewal Fees

A brief description of payment as well as repayment of renewal fees is given below-

Payment of Renewal Fees

The payment of the renewal fees needs is made to the Indian Patent Office before the end of the related year. For example, the Renewal fee for 5th year must be cleared before the expiration of 4th year from the date of the patent. The renewal fee is a obligatory due, the expiry of the 2nd year from the date of the patent and each succeeding year. The patentee can even pay an advance renewal fee for two years or more as per the Indian Patents Act[1].

Repayment of Renewal Fees

For the repayment of the renewal fee, the patentee has to cite the relevant patent number, date of the patent and the year in respect of which the renewal fee paid, to make the renewal payment request.

Additional Patent

In the case of an additional patent registration, no renewal fee needs to pay, and the fee payment schedule persists the same as of the principal patent. But in case the other patent becomes an independent patent, it shall follow the guidelines of an ordinary independent patent.

There is a provision of continuation up to 6 months if the patentee funds the directed penalty fee for the renewal. If the renewal fees not given within the extension period, the patent desists to exist and moves on the public domain.

Pending Fees

Another essential point to recollect is that if the patent is granted later than two years of the date of filing of the application; the pending fee payment has to be given within three months from the date of the patent allowance as specified in the patent register.

The summary of the whole method of patent renewal in India is that the renewal fees should be met before the commencement of each succeeding year. Nevertheless, this period is extendable by 6 months by requesting an extension of the term along with the directed penalty fees.

  • The evidence should support the claim of the patentee that the failure of payment of fees was not intentional and there was no undue delay in applying for restoration of the patent.
  • The controller of patent can call for additional evidence in case the provided evidence is not satisfactory.
  • If the Controller does not agree that it is a prima facie case of restoration, the applicant should be notified. The applicant has the choice to present his reasons for restoration within one month, if the applicant does not present himself within one month the application for restoration can be refused.
