A complete guide under the Patents Act 1970 - eligibility, procedure, forms, fees, and timeline
A patent is an exclusive right granted by the Government of India to an inventor for a new invention for a limited period (20 years) in exchange for full public disclosure. It is governed by the Patents Act, 1970 and the Patents Rules, 2003, administered by the Indian Patent Office (IPO) under CGPDTM.
Before filing, search existing patents to check if your invention is novel. Use the Indian Patent Advanced Search System (InPASS) at ipindia.gov.in and global databases (USPTO, EPO Espacenet). A patent agent can conduct a comprehensive freedom-to-operate search.
The patent specification is the core document. It must describe the invention completely so a person skilled in the field can reproduce it.
Provisional Specification: Brief description to secure priority date. Must be followed by a complete specification within 12 months.
Complete Specification: Must include - Title, Field of Invention, Background, Summary, Drawings (if any), Detailed Description, Claims, and Abstract.
Claims define the legal scope of protection. Drafting claims is a specialist skill - engage a registered Patent Agent.
File at one of four Indian Patent Office branches based on the applicant's residence / place of business: Delhi, Mumbai, Kolkata, or Chennai. Filing can also be done online via the IP India e-filing portal.
Submit: Form 1 (Application), Form 2 (Specification), Form 3 (Statement of foreign applications), Form 5 (Declaration of inventorship), Power of Attorney (if filing through an agent).
The application is ordinarily published in the Official Patent Journal 18 months from the filing or priority date (whichever is earlier). You can request early publication using Form 9 (additional fee applies).
After publication, the applicant gets provisional protection - third parties can inspect the application.
Publication is not automatic examination. You must file Form 18 (Request for Examination) within 48 months of the priority date. Failure to request examination leads to the application being treated as withdrawn.
An Examiner reviews novelty, inventiveness, and clarity of claims. You will receive a First Examination Report (FER) and have 6 months (extendable by 3 months) to respond.
If the Controller is satisfied after examination and any objection proceedings, the patent is granted and published in the Official Journal. The patent is valid for 20 years from the date of filing, subject to payment of annual renewal fees.
Annual renewal fees must be paid to keep the patent in force.
