Patent opposition/revocation offers third parties an opportunity to oppose/revoke a patent by challenging the validity thereof within a certain period of time. Indian patent law allows for filing of a representation by way of opposition before the Indian Patent Office (IPO) any time before the grant of a patent, a notice of opposition before the IPO within one year of the grant of a patent and also a revocation petition before the High Court for invalidating a patent.

Successfully opposing and/or revoking a patent requires in-depth knowledge and understanding of technology and law coupled with comprehensive research, effective strategy, and skillful implementation.
