Patent Revocation: Grounds, Process & Legal Framework

Revocation of Patent refers to the legal process by which a granted patent is cancelled or invalidated, either wholly or partially. Common grounds for revocation include lack of novelty, inventive step, or patentable subject matter, as well as procedural irregularities.

What is Patent Revocation?

Patent revocation is the statutory process of cancelling a granted patent when it does not fulfill the required criteria of intellectual property law. It assures that only genuinely novel and non-obvious inventions are granted protection, avoiding unjust monopolies and promoting competitive fairness. Revocation can take place due to insufficient novelty, obviousness, lack of disclosure, fraud, or when a patent causes harm to public interest, like limiting access to vital medicines. By removing invalid patents, revocation protects innovation, encourages technological advancement, and ensures that intellectual property rights benefit inventors and society equally.
