Patent Registration Subsidy for Tamil Nadu MSMEs — 75% Up to ₹3L — Frequently Asked Questions

You can receive up to ₹3,00,000 for a single registered patent. The amount is worked out as 75% of what you spent on registration, so the ₹3 lakh ceiling only comes into play on larger claims.

Two categories. First, the cost of filing the patent application. Second, the first maintenance fee charged once the patent is granted. Filing costs for patents registered in India and for international patents are both eligible.

Any micro, small or medium manufacturing enterprise in Tamil Nadu qualifies — whether it is newly set up or has been operating for years. The only locational requirement is that the unit sits somewhere in the state.

No. The scheme is always open and applications are accepted on a rolling basis, so there is no closing window to chase. One time rule does apply, though: your application should be filed within 6 months of obtaining the patent registration. The same six-month limit is stated for trade mark registrations and geographical indications.

No. This is a subsidy that pays back expenses you have already incurred. It is not an investment, and it does not dilute your ownership of the enterprise.

Everything is done online on the MSME Department portal. You begin by registering with your name, date of birth, Aadhaar number, email ID and mobile number, and creating a password that meets the specified criteria. You then log in using the credentials sent to your registered email and mobile number. From the Schemes menu, pick the relevant scheme, choose New Application, complete all mandatory fields, review the information, accept the terms, declaration and privacy policy, and proceed — noting down the reference number shown on screen.

Finally, tick the checkboxes and click Submit Application; an SMS will confirm that your application has reached the GM/DIC / RJD.

Not always. Reimbursement of up to ₹1,00,000 may be processed without documents at all. For larger amounts, documents are required and the claim goes through full verification, so keep your filing receipts and registration papers handy.

The GM/DIC / RJD — the General Manager, District Industries Centre or Regional Joint Director — handles the file. They verify the application details and the uploaded documents against the eligibility conditions, and the subsidy is approved and disbursed once the patent registration and the related costs are validated.

Yes. The scheme covers the cost of filing patent applications in India as well as international patents.
