Patent Royalty under section 152 of the Income-tax Act, 2025 (section 80RRB of the 1961 Act) explained: this guide covers what Section 152 Patent Royalty means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
1. Patent Royalties: A Growing Income Stream for Indian Inventors
India has been producing a growing number of patents across technology, pharmaceuticals, engineering, and biotechnology sectors. Indian inventors -- working in research institutions, academia, startups, and corporations -- increasingly hold patents and earn royalties from licensing these innovations. Section 152 specifically recognises this income and provides a tax deduction that encourages innovation and reduces the tax burden on inventors who have invested years developing their intellectual property.
2. Section 152: Core Provisions
Section 152 of ITA 2025 provides:
- Deduction: Lower of actual royalty received OR Rs 3,00,000 per year
- Eligible taxpayer: Indian resident individual who is the true and first inventor
- Patent requirement: Patent must be registered under the Patents Act 1970 in India
- Royalty definition: Consideration for use of or the right to use any patent
- Regime: Old regime only
3. True and First Inventor: The Core Requirement
The most important condition is that the claimant must be the TRUE AND FIRST INVENTOR of the patent:
- The claimant must be the original creator of the invention -- not someone who purchased, inherited, or was assigned the patent
- Joint inventors: each joint inventor can claim Section 152 independently on their share of royalty
- Employed inventors: if an employee invents and the employer holds the patent: the employer cannot claim Section 152 (employer is not the inventor); the employee also cannot claim if they do not personally hold the patent
- Startup founders who are inventors and hold patents: can claim if they are personally named inventors
4. Employment and Patent Ownership: A Complex Area
In many corporate and research contexts, the employer contractually owns the invention even though the employee made it. This creates complications:
- If the employer owns the patent: the inventor-employee typically cannot claim Section 152 (they do not receive royalty as an inventor)
- If the employer licenses back the patent to the inventor for independent commercial exploitation: Section 152 may be available
- Researchers in publicly funded institutions (IITs, CSIR) may hold personal patents on breakthrough research: royalty from these patents may qualify
5. Pharmaceutical Patent Royalties
Indian pharmaceutical researchers and scientists who hold patents on drug formulations, molecules, or processes:
- Royalty received from pharmaceutical companies licensing the patent: eligible for Section 152
- The inventor must be an Indian resident individual -- not the pharmaceutical company that employs them
- Generic drug patents and process patents: eligible if held by individual inventor
6. Technology and IT Patent Royalties
Indian technology inventors in software, AI/ML, IoT, and electronic systems:
- Software patents (if patented under the Patents Act 1970 -- India has specific software patentability rules): royalty eligible for Section 152 if the inventor holds the patent
- Technology entrepreneurs who patent their innovations and license them: key beneficiaries
- Patent pools: if an inventor contributes to a patent pool and receives collective royalties, specific rules apply
7. Interaction with Section 151 and Section 58
Multiple deductions can be combined:
- An inventor who is also an author can claim BOTH Section 151 (Rs 3L for literary work) and Section 152 (Rs 3L for patent royalty) in the same year
- If total professional receipts include both author royalties and patent royalties: Section 58 (50% of total receipts) plus both Section 151 and Section 152 deductions
- Maximum combined deduction from Section 151 + Section 152: Rs 6L per year
8. Foreign Patents and Section 152
If the patent is registered in a foreign country but the inventor is an Indian resident:
- Section 152 specifically refers to patents registered under the Patents Act 1970 -- Indian registration is generally required
- If the same invention is patented both in India and abroad: royalty for use of the Indian patent qualifies
- Royalty for use of a foreign-only patent: may not qualify for Section 152 even if the inventor is an Indian resident
9. Documentation for Section 152
To claim Section 152:
- Copy of Indian patent certificate (identifying the claimant as inventor)
- Royalty agreement with the licensee
- Annual royalty account statements from licensees
- Self-declaration confirming status as true and first inventor
- If joint invention: documentation of the inventor share of royalties
