Restoration of patents refers to the revival process of a lapsed or ceased patent within the jurisdiction of India, typically occurring due to non-payment of the prescribed renewal fees within the stipulated time frame.


The essence of the patent system lies in promoting innovation by providing inventors exclusive rights over their creations for a defined period, typically 20 years.

In the event of a patent lapse due to non-payment of renewal fees, the invention falls into the public domain, leading to the loss of these exclusive rights. Thus, restoration of patents allows inventors or patent holders to regain their exclusive rights, providing control over the usage and commercialisation of their inventions even after the patent has lapsed.


The restoration of patents in India involves a defined procedure under the Indian Patents Act, 1970. The key steps include:

  1. Submitting an application for restoration within 18 months from the date the patent lapsed.
  2. Providing a statement explaining the circumstances leading to the failure to pay the renewal fees.
  3. Upon the Controller’s satisfaction that the failure to pay the renewal fee was unintentional and there was no undue delay in seeking restoration, they may publish the application for opposition.
  4. If no opposition is filed, or if the opposition is decided in favour of the applicant, the patent is restored.


Despite its advantages, the restoration of patents carries risks. The process may attract opposition, leading to potential legal disputes.

The controller may based on the circumstances, deny the restoration request and the lapsed patent may not be restored.

Also, the restoration cannot negate any third-party actions that occurred while the patent was lapsed, which may include manufacturing, selling, or importing the invention.


Successful restoration of a patent reinstates the patent holder’s exclusive rights over the invention, allowing control over its use, sale, and importation. It also paves the way for licensing or selling the patent rights.
