Post-grant opposition allows any person interested or affected by a granted patent to file a petition with the Indian Patent Office (IPO) challenging its validity. The opposition must be filed within one year from the date of publication of the grant of the patent in the Official Gazette. The grounds for opposition typically include lack of novelty, lack of inventive step, non-compliance with patentability criteria, anticipation by prior art, and public interest considerations. The IPO considers the opposition and conducts a thorough examination of the patent in light of the objections raised.
