Patent

Patent is a statutory exclusive right granted by the Indian Patent Office (IPO) for a novel, non-obvious, and industrially applicable invention. A granted patent gives the holder the right to prevent anyone else from making, using, selling, or importing the patented invention in India for 20 years from the filing date. In exchange, the inventor publicly discloses the invention in the patent document — the disclosure-for-exclusivity bargain that underlies the patent system globally.

For deep tech, biotech, pharmaceutical, and hardware startups, patents are the primary mechanism for creating legally enforceable IP barriers around core technology.

Who it applies to

• Startups with novel technical inventions — new drug compounds, hardware designs, manufacturing processes, materials, or software-driven systems with a demonstrable technical effect
• Biotech and pharmaceutical companies filing before initiating clinical trials or disclosing results publicly
• Hardware startups protecting circuit designs, mechanical systems, or novel manufacturing methods
• DPIIT-recognised startups seeking the 80% fee rebate and expedited examination

Eligibility requirements

An invention must meet four conditions:

1. Novel: Not previously disclosed anywhere in the world — in published papers, earlier patents, or any public demonstration
2. Inventive step: Non-obvious to a person skilled in the relevant field through routine experimentation
3. Industrially applicable: Can be made or used in any industry (interpreted broadly)
4. Not excluded under Section 3: Mathematical methods, business methods, computer programs per se, discoveries of natural laws, and certain pharmaceutical forms (new uses of known substances) are excluded

The application process

DPIIT-recognised startups: File for expedited examination under the Startup India IP facilitation scheme. The 80% fee rebate applies to filing, examination, grant, and renewal fees. Expedited examination can compress the filing-to-grant timeline to 18–36 months.

Provisional vs. complete application

A provisional application establishes a priority date with a brief description, buying 12 months to file a complete specification. Use it when the invention is not fully developed but a public disclosure (conference, paper, investor demo) is imminent.

A complete application contains the full specification, claims, drawings, and abstract. The claims define the exact scope of protection — the most consequential part of the document.

File before any public disclosure. A single detailed public disclosure — conference talk, published paper, or sufficiently technical demo day pitch — can invalidate novelty globally. India has a 12-month grace period for the inventor's own disclosures, but PCT (Patent Cooperation Treaty) international filings have no grace period. If international protection matters, file before any disclosure.

What most founders miss

Software must be claimed around a technical effect, not the code. Computer programs per se are excluded from patentability in India under Section 3(k). However, a software-driven system that produces a measurable technical effect — faster hardware operation, a novel control outcome, a demonstrable improvement in a physical process — may be patentable as a technical solution. Claims must be drafted around the technical effect by an experienced patent attorney. Filing a software patent without professional drafting is likely to result in a Section 3(k) objection that is expensive to overcome.

Filing discloses the invention permanently. Once a patent application is published (18 months after filing), the technical description is public regardless of whether a patent is granted. A startup that files, fails to prosecute, and lets the application lapse has given away its technical disclosure with no protection. For inventions that cannot be reverse-engineered from the product, a trade secret strategy may offer better long-term protection than a patent.

Section 54GB creates a tax incentive for IP transferred to the company. If a founder holds the patent personally (common when the invention was developed before the company was incorporated) and transfers it to the company, Section 54GB provides a capital gains exemption on the transfer if structured correctly. A registered patent with a professional valuation makes the transfer cleaner and more defensible in due diligence.

Annual renewal fees must be paid to keep the patent in force. A granted patent must be renewed annually by paying renewal fees to the IPO. Failure to pay renewal fees within the grace period results in lapse of the patent — the invention enters the public domain. Set up a renewal tracking system; many startups discover lapsed patents during M&A due diligence.
