The validity of a patent in India refers to the duration for which the patent rights granted to the inventor remain enforceable, allowing the patent holder exclusive rights to make, use, sell, or license the invention. Validity Period of a Patent in India The term of a patent is 20 years from the date of filing the patent application. This 20-year period applies to patents filed on or after January 1, 1995, in compliance with the Trade-Related Aspects of Intellectual Property Rights (TRIPS) Agreement obligations. For patent applications filed before January 1, 1995, the validity may vary but generally lasts 14 years from the date of grant. Conditions During the Validity Period 1. Payment of Renewal Fees To maintain the patent rights, the patent holder must pay annual renewal fees starting from the third year of filing. Failure to pay these fees can result in the patent lapsing before the 20-year term expires. 2. Patent Rights During this validity period, the patent holder has the exclusive right to prevent others from making, using, selling, or distributing the patented invention without permission. The patent can be licensed or assigned to others. 3. Post-Expiry Once the patent expires, the invention enters the public domain, allowing anyone to use it freely. The patent holder no longer has exclusive rights after expiration. Special Cases and Extensions India does not typically allow patent term extensions or patent term adjustments like some other countries. However, in specific cases such as pharmaceutical patents, provisions under the Patent Act, 1970 (amended) allow for some regulatory exclusivity through data exclusivity norms, but this does not extend patent validity. Compulsory licensing provisions may affect enforcement but do not shorten the 20-year term itself. Under New Frameworks (BNS/BNSS or Others) The core patent validity period remains consistent with international standards (20 years). Modern reforms and digital patent filing processes (under frameworks like BNS or BNSS) streamline patent maintenance but do not change the fundamental term. These frameworks might focus more on timely renewals and compliance to prevent unintended lapses. Summary In India, a patent is valid for 20 years from the filing date of the application, subject to the payment of annual renewal fees. After expiry, the invention becomes public property. This term aligns with international norms and is the standard for patent protection in India under current laws and modern frameworks.
