| Law / office | Patents Act, 1970 (Rules amended 2024) • Indian Patent Office |
| Fee — individual / startup / MSME | ₹1,600 (e-filing, up to 30 pages & 10 claims) |
| Fee — large entity | ₹8,000 |
| Request for Examination (Form 18) | Mandatory — within 31 months (filings on/after 15 Mar 2024) |
| Term | 20 years from the date of filing |

Process: Patentability search → file (provisional or complete) → complete spec within 12 months of provisional → publication at 18 months → Request for Examination → First Examination Report → response → grant. Renewal fees apply annually from the 3rd year. Startups (DPIIT) get up to 80% lower fees and free facilitator support under SIPP.

What Goes Wrong If You Delay / Miss Steps
Lost priority
Not filing the complete spec within 12 months abandons the application.
Deemed withdrawn
Missing the 31-month examination request permanently withdraws the application.
Patent lapses
Missing annual renewal from year 3 makes the patent unenforceable.
Someone files first
India is first-to-file — delay risks losing the invention to another applicant.
