Invalidation Proceedings

Section 64 of the Indian Patents Act outlines circumstances under which a granted patent can be revoked. Following are the primary grounds on which patents can be invalidated during the legal course of action or during due-diligence activities while commercializing the relevant product. 1) Novelty: The claimed invention is anticipated by a single publically known reference. If the claimed invention is lacking novelty regards to the earlier disclosed knowledge or prior use, this can invalidate the patent.

2) Obviousness: If the claimed invention is such that it seems obvious to any person who is skilled in the sector, owing to the fact that the invention does not involve an inventive step, the such claimed invention can be invalidated on the basis of obviousness. If a person such as an expert, appointed by the court for testimony, deposes that the claimed invention is evident and easily discoverable, as of on the priority date, then the claim of the patent may be liable to be invalidated.

3) Subject of the claim of the patent is not an invention: Patent Offices of different countries have patent laws, which define patentable subject matter. A claimed subject matter that does not fall within the criteria of the patentable subject matter such as defined by Section 3 of the Indian Patent Act, can be invalidated on the grounds that the subject matter is not an invention according to the patent law of that country.

4) Patent wrongfully obtained: Applicants of the patent should be the inventors who have worked on the invention. Insufficient disclosure of inventors' details or disclosure of a person as an inventor who is wrongfully mentioned to be the inventor can form the basis of invalidation of the patent. The issue here is that a patent may be invalidated or revoked in many jurisdictions, if the patent applicant or inventor is not the true inventor.

5) Insufficient disclosure of the invention: It is the duty of the inventors to disclose all information relating to the invention, including the best mode to accomplish the invention, all art known to the inventor, and any information that might render the invention unpatentable, such as a public use or published description of the invention occurring more than one year prior to the filing date of the patent application. Any deliberate efforts for insufficient disclosure or description of information related to the invention can form the basis for invalidation of the patent. Additionally, if the disclosure contains false representation of any fact or statement, the patent may be liable to be rejected.

6) Unsubstantiated Disclosure: In case the claims included in the description of the patent are not satisfactorily and completely substantiated, the inventor runs the risk of losing his exclusive right in the form of a patent, of the invention.

7) Failure to disclose information relating to foreign applications as required under Section 8 of the Indian Patent Act.

Opposition Proceedings


Earlier amendments of The Patents Act 1970 provided provision for only one type of opposition system, i.e. the Post-grant opposition system. The currently amended act now also provides for a Pre-grant opposition system, making two opposition opportunities being made available for third parties. While in pre-grant opposition, any person can represent, in writing to the Controller General of Patents for any patent application that is published but not granted. The pre-grant opposition can be filed on a number of grounds as specified under section 25 (1) of the act. respect to the post-grant opposition, any interested person can file a request before the expiry of a period of one year from the date of publication of grant of the patent. Similar to the pre-grant opposition, a post-grant opposition can be filed on number of grounds as specified under section 25 (2) of the act.
