Official fees are set in the First Schedule to the Patents Rules, 2003. There are two fee columns: a lower one for natural persons, startups, small entities and educational institutions, and a higher one, five times as much, for everyone else. You claim the lower rate by filing Form 28 with proof of status.
The filing fee covers a specification of up to 30 pages with up to 10 claims. Each additional page and claim is charged separately, so a focused specification is cheaper. Filing a provisional specification first doesn't add a second filing fee.
| Renewal years | Individual / startup / small entity / educational institution | Others |
|---|---|---|
| 3rd to 6th year | ₹800 a year | ₹4,000 a year |
| 7th to 10th year | ₹2,400 a year | ₹12,000 a year |
| 11th to 15th year | ₹4,800 a year | ₹24,000 a year |
| 16th to 20th year | ₹8,000 a year | ₹40,000 a year |
Renewal fees are due every year from the third year after filing. If the patent is granted later, fees for the years already passed are paid together after grant. Paying online for at least four years in advance reduces the fee by 10%.
