What is Patent Application Filing?
A patent gives you the exclusive right to make, use and sell your invention in India for 20 years from the filing date. Startups, small entities and individuals pay reduced government fees.
The Patent Office examines an application only after a request for examination (Form 18), which must be filed within 31 months of the priority date for applications filed from 15 March 2024. DPIIT-recognised startups can request expedited examination.
