Introduction
A resident individual patentee with qualifying royalty from an eligible registered patent may deduct the lesser of that income or ₹3 lakh. The section also regulates compulsory-licence royalties, foreign remittance and certificate evidence.
Key takeaways
Resident patentee royalty
A resident individual patentee may deduct qualifying royalty from a patent registered on or after 1 April 2003, up to the lower of that royalty income and ₹3,00,000.
Foreign receipts and certificate
Foreign-source royalty counts only when brought into India in convertible foreign exchange within the statutory period; prescribed certificates must accompany the return.
Who qualifies
The deduction is available to an individual who is:
- Resident in India;
- A "patentee" - the true and first inventor recorded as such (including joint patentees);
- In receipt of royalty income from a patent registered on or after 1 April 2003 under the Patents Act, 1970; and
- Has gross total income for the year that includes such royalty income.
How much can be deducted
The deduction equals the whole of the royalty income, or ₹3,00,000, whichever is less.
If a compulsory licence has been granted for the patent, the royalty counted for this deduction is capped at whatever the Controller of Patents has fixed as the licence terms - not any higher negotiated figure.
For royalty earned from a source outside India, only the portion actually brought into India in convertible foreign exchange within six months of the end of the tax year (or such extended period as allowed) counts toward the deduction.
Procedural requirement
A prescribed certificate must be furnished along with the return of income to claim this deduction; for foreign-sourced royalty, an additional certificate is required. Once claimed and allowed under this section, the same royalty income cannot be deducted again under any other provision.

Compute the deduction
Lower of eligible royalty and ₹3,00,000, with the prescribed certificate furnished with the return. The same income cannot be deducted under any other provision.
Practical checklist
Do
- Keep patent registration, patentee status, royalty agreement and the prescribed certificate.
- Where royalty originates abroad, check convertible-foreign-exchange receipt and the additional certificate.
Avoid
- Do not treat product-sale revenue as qualifying patent royalty.
- Do not claim the same patent income again under another deduction provision.
Illustrative example
Worked example: Indian and foreign patent royalty
Hypothetical facts (illustration only, not a real taxpayer): Mr. Menon, a resident individual, is the true and first inventor recorded as patentee of a patent registered after 1 April 2003. During the tax year he receives royalty of ₹5,00,000 from an Indian licensee and ₹1,00,000 from a foreign licensee. Of the foreign royalty, ₹60,000 is brought into India in convertible foreign exchange within six months of the end of the tax year. No compulsory licence has been granted.
Indian royalty
₹5,00,000 counts in full.
Foreign royalty
Only the ₹60,000 repatriated within the time counts; the remaining ₹40,000 is not taken into account for this deduction.
Eligible income
₹5,00,000 + ₹60,000 = ₹5,60,000.
Cap
Deduction is the lower of ₹5,60,000 and ₹3,00,000 = ₹3,00,000.
Outcome
- Section 152 deduction: ₹3,00,000, subject to furnishing the prescribed certificates (including the one for foreign income) with the return.
- The cap is reached even without the foreign royalty, but the foreign-income certificate matters if Indian royalty alone were below ₹3,00,000.
Glossary
- Patentee
- The person holding the relevant registered patent rights.
- Compulsory licence
- A patent licence whose royalty for this deduction is capped by the Controller's settled terms.
Frequently asked questions
Is this the deduction people call "80RRB"?
Yes - the same patent royalty deduction, now numbered Section 152 under the Income-tax Act, 2025.
What's the maximum I can deduct?
₹3,00,000, or the actual royalty income, whichever is less.
Does this apply to a company that owns a patent?
No - Section 152 is specifically for a resident individual who is the patentee (the true and first inventor), not a company.
