Every other calculator asks these same questions and returns one confident rupee figure. Ours will not, because a figure built from a formula rather than from real transactions is a guess wearing a suit. What you get instead is the cost you are committed to, an honest read of how sellable the patent is, and, if it already earns money, arithmetic you can check.
It does not value your patent. Nothing on this page is a valuation, an opinion, or advice, and none of it should be relied on in a negotiation, a filing or a set of accounts.
Where the numbers come from. Renewal fees are arithmetic on the First Schedule to the Patents Rules, last checked 2026-08-07. Royalty bands are indicative ranges for the field, printed on screen rather than hidden, and the discount rate is stated. The readiness score is our own reading of the factors buyers actually price.
It cannot see your claims. What a patent is worth turns on what the independent claims cover and whether anyone can design around them. No questionnaire reaches that.
