Post Grant Opposition: When To File?

The Section 25(2) of the Indian Patent Act, 1970 declares the grounds to approve post-grant opposition, such as:

  • The publishing of claim has been before, filed or published before the filing of the applicant
  • Known publicly or practiced before the claim of the prior art
  • Obtained through wrongful and frivolous means
  • Obvious and lacks novelty
  • Specifications do not adequately describe the invention or the methods through which the same can perform
  • If the invention doesn’t amount to an invention as contemplated under the Indian Patent Act
  • Lacks adequate description of how to implement the underlying invention
  • The invention was foreseen in the light of knowledge available within any local or native community in India or elsewhere

A post-grant opposition is not the only method through which the legality or validity of a patent gets cross-examine. There are other means as well, such as “Revocation of Patent Grants”. However, unlike pre-grant proceeding, initialization of revocation can only be by a party with a strong interest or by petition of the Central Government or a counterclaim in a suit for infringement of a patent. The rise in the petition can be either with the IPAB or the High Court depending on whether it is a counterclaim of suit or not.

Viewing the complexity of Indian patent act, it is important for applicants to stay prepared before filing patents. Since a patent can face challenges even after the grant, we can’t take it for a grant.
