About Patent Filing — Provisional & Complete Specification

A clear overview, in simple terms — what it is, why it matters, and how we handle it.

Quick answer

An Indian patent application can start with a provisional specification that secures your filing date, followed by the complete specification within 12 months. The application is published after 18 months (earlier on request) and examined only after a request for examination, which must be filed within 31 months of the priority date under the 2024 rules. A granted patent lasts 20 years from the filing date, subject to annual renewal fees.

Drafting the claims decides how much protection you actually get, so applications are prepared by registered patent agents. Startups and small entities pay reduced official fees and can request expedited examination.

If you plan to file abroad, the Indian filing date can be claimed as priority in other countries within 12 months, or through a PCT application.
