What it really costs to file a patent in India
A patent cost has two parts: statutory government fees paid to the Indian Patent Office (IPO) and the attorney fee for drafting and filing. Government fees depend entirely on your applicant category — an individual, startup or small entity (MSME) pays roughly one-fifth of what a large company pays, an ~80% rebate baked into the fee schedule.
Government fee schedule — e-filing
These are the official IPO e-filing fees. The first column applies to a natural person, startup or small entity; the second to any other applicant (companies and large entities).
| Fee item (e-filing) | Individual / Startup / Small | Others (Company) |
| Filing — Form 1 | ₹1,600 | ₹8,000 |
| Request for Examination — Form 18 | ₹4,000 | ₹20,000 |
| Each claim beyond 10 | ₹320 | ₹1,600 |
| Each page beyond 30 | ₹160 | ₹800 |
| Early publication — Form 9 | ₹2,500 | ₹12,500 |
Worked example
A straightforward complete application with a request for examination, 10 claims and 30 pages — no excess, no early publication. Government fee plus a ₹15,000 attorney fee:
Key terms explained
Provisional vs complete
A provisional specification locks in your priority date early and cheaply while the invention is still being refined. You must file the complete specification within 12 months, or the application lapses.
Request for Examination (RFE)
The IPO does not examine an application until you file Form 18. Without an RFE the application is treated as withdrawn, so this fee is effectively mandatory to move toward grant.
Excess claims & pages
The base fee covers the first 10 claims and 30 pages. Each additional claim and page carries a per-unit fee, so tight, well-drafted specifications keep costs down.
Early publication
Applications publish automatically at 18 months. Filing Form 9 publishes sooner, which can start your provisional rights earlier — useful if you need to enforce quickly, but it is optional.
