Patent opposition in India exists in two forms: pre-grant opposition (filed after the patent application is published at 18 months but before the patent is granted) and post-grant opposition (filed within one year of the patent grant date). Pre-grant opposition can be filed by any person under Section 25(1) of the Patents Act, 1970, and does not require the opponent to be personally affected. Post-grant opposition, under Section 25(2), also allows any person to oppose, but must be filed within the strict one-year window. The grounds for patent opposition are comprehensive and include: the invention is not patentable (lack of novelty, obviousness, or industrial application), the invention falls within the exclusions of Section 3, the patent was obtained wrongfully (the inventor is not the true and first inventor), the complete specification does not sufficiently describe the invention, the claims are broader than what is actually invented, the applicant failed to disclose information about foreign applications (a common ground based on Section 8 non-compliance), and the patent is contrary to natural justice or public interest. Patent opposition is one of the most technically demanding areas of IP law. The opponent must demonstrate, with specific prior art evidence, that the claimed invention does not meet the patentability criteria. This requires both deep technical knowledge (to understand the invention and the prior art) and legal expertise (to present the argument effectively within the procedural framework). Our team of patent attorneys and technical experts handles both sides — filing pre-grant and post-grant oppositions to block invalid patents, and defending our clients’ patents against third-party oppositions.

Pre-grant opposition can be filed by any person after the patent application is published but before it is granted, and has no official filing fee. Post-grant opposition can only be filed by an "interested person" (a competitor or stakeholder) within one year of the patent grant, and requires a prescribed government fee.
Grounds include: (1) Prior publication or public use, (2) Lack of novelty or inventive step, (3) Insufficient disclosure of the invention, (4) Failure to disclose foreign application details, or (5) The invention falls under non-patentable categories (e.g. Section 3 of Patents Act).

Patent Opposition is a vital legal and regulatory requirement in India designed to ensure full statutory compliance, protect legal rights, and establish clear operational legitimacy. Completing this ensures your business or personal affairs remain protected under relevant Indian regulatory frameworks.
Any business entity (such as Private Limited Companies, LLPs, OPCs, Partnerships, or Sole Proprietorships), registered organisation, or individual whose activities fall under the purview of this statutory requirement must complete Patent Opposition. Early execution mitigates legal risks and compliance penalties.
I-Pro Solutions CA/CS and legal team manages the entire process end-to-end: (1) Initial documentation review and eligibility verification, (2) Drafting of legal applications, agreements, or statutory forms, (3) Submission to the appropriate authority (MCA, Income Tax Department, Trademark Registry, etc.), and (4) Tracking and follow-up until final approval or registration is delivered.
Generally, you will need basic KYC documents of directors/partners/applicants (PAN Card, Aadhaar Card, passport-size photographs), proof of registered office or address (electricity bill, rent agreement, NOC), and entity incorporation certificates or financial statements where applicable. I-Pro Solutions team provides a exact checklist tailored to your case upon onboarding.
Depending on government processing windows and verification timelines across regulatory bodies, Patent Opposition is typically completed within 3 to 14 business days once all verified documents are submitted to I-Pro Solutions portal.
