Service Overview

Everything you need to know about this service

Patent Revocation refers to the cancellation of a granted patent by a competent authority if it is found that the patent does not comply with the provisions of the Indian Patent Act. A patent may be revoked if the invention lacks novelty, is obvious, or was wrongfully obtained.
Any interested person, competitor, or government authority can file a petition to revoke a patent. The revocation process involves reviewing the patent details, identifying legal grounds for cancellation, and submitting a revocation petition before the High Court or Patent Office.
Revoking an invalid patent protects businesses from unfair monopoly rights and ensures that innovations remain accessible when they do not meet patentability requirements. Our experts assist in analyzing patents, preparing strong legal arguments, and representing clients during the revocation process.
