Patent Opposition support from our Patent team, handled end-to-end as part of our Intellectual Property practice.
Pre-grant opposition can be filed at any time after publication and before the patent is granted. Post-grant opposition must be filed within 12 months from the date of publication of grant. The entire opposition proceeding, including evidence stages and hearing, typically takes 12 to 24 months.
We make legal and intellectual property filings seamless, secure, and fully transparent. Here is how we handle your assignment from start to finish:
Understand your goals, check eligibility, and draft the filing roadmap.
Collect required records and conduct compliance checks for errors.
Draft and submit applications to the registry within 48 business hours.
Monitor application progress and respond to office actions/objections.
Handover certified registrations and provide post-filing support.
Pre-grant opposition (Section 25(1)) is filed before the patent is granted and is a simpler, less formal process. Post-grant opposition (Section 25(2)) is filed within 12 months of grant publication and involves a formal Opposition Board constituted by the Controller.
Common grounds include lack of novelty, obviousness, non-patentable subject matter under Section 3 (e.g., software per se, business methods), insufficient disclosure, wrongful obtainment, and anticipation by prior publication or prior claiming.
While pre-grant oppositions require identification of the opponent, the threshold for standing is lower than post-grant opposition — any person can file a representation. However, anonymous filings are not accepted.
