What’s in this article
Mumbai’s startup story is mostly told through fintech and media — sectors where patents play a limited role. But the city also builds genuine invention: healthtech, materials, hardware, climate and industrial technology, much of it linked to Mumbai’s deep research and manufacturing base. For those startups, a patent is the difference between owning an invention and watching a better-funded competitor copy it.
Patents in India are governed by the Patents Act, 1970. A Mumbai startup files with and is examined by the Mumbai branch of the Indian Patent Office. This guide covers what is patentable, the provisional-first route, costs and the grant timeline — and, importantly, when a Mumbai startup should not bother with a patent at all.
A patent is powerful where there is a real invention — and pointless where there is not.
Why Mumbai startups patent
A patent gives a Mumbai deep-tech, healthtech or hardware startup three things: a defensible moat against fast followers, a balance-sheet asset investors value, and a priority date that fixes ownership of the invention in time. But it is worth being honest about when a patent does not apply — for most fintech and media startups, Section 3 exclusions mean the reliable IP rights are trademark and copyright, not patents.
The Mumbai patent office
The Indian Patent Office has four branches — Delhi, Mumbai, Kolkata, Chennai. Maharashtra falls under the Mumbai branch, so a Mumbai startup files with and is examined by the Mumbai patent office. The process and fees are uniform nationwide; jurisdiction only sets which examiners review the specification and where any hearing is listed.
What is patentable in India
An invention must be novel, involve an inventive step, and be capable of industrial application. Section 3 excludes a range of subject matter:
- Section 3(k) — computer programs per se, algorithms, business methods.
- Section 3(d) — new forms of known substances without enhanced efficacy.
- Section 3(j) — plants, animals, biological processes.
A patentability search before drafting confirms eligibility and prior art. For Mumbai healthtech and materials startups, this step also flags Section 3(d) issues early.
The provisional-first route
For most Mumbai deep-tech and hardware startups, the right first move is a provisional specification under Section 9 — it locks the priority date without full claims and gives 12 months to file the complete specification. That 12 months is runway to keep iterating and to raise the round that funds full drafting.
Costs, RFE and the grant timeline
The government fee is ₹1,750 per application for individuals, DPIIT startups and small entities; ₹8,000 for large entities. The larger cost is attorney drafting — ₹40,000-1,50,000 for a complete specification. Timeline: provisional, complete within 12 months, request for examination within 48 months, First Examination Report 12-18 months after, response within 6 months, then grant. Total 3 to 5 years — faster with expedited examination for DPIIT startups.

- Filing a patent for a business method. Section 3(k) excludes it — the drafting fee is wasted.
- Disclosing before filing. A demo or pitch before the provisional destroys novelty.
- A prototype-only provisional. It cannot support a broad complete specification.
- Missing the 48-month RFE. No request for examination, no patent. Docket it.
- Skipping the patentability search. It tells you whether to file at all.
Patent the genuine invention. For everything else, protect the brand and the code.
People also ask
Should a Mumbai fintech file patents?
Usually only selectively. Section 3(k) excludes business methods and programs per se. A genuinely technical component may be patentable; the core fintech IP is trademark and copyright.
Can a Mumbai healthtech startup patent a medical device?
Often yes. A novel medical device or its inventive mechanism can be patentable, subject to Section 3(d) for substances. A patentability search confirms the position before drafting.
Does a Mumbai DPIIT startup get faster patent examination?
Yes. DPIIT-recognised startups are eligible for expedited examination, which can significantly compress the grant timeline.
Is a PCT application worth it for a Mumbai startup?
If international markets are on the roadmap, yes. PCT filed within 12 months of the Indian provisional preserves the Indian priority date across 150+ countries.
Frequently asked questions
Which patent office handles Mumbai applications?
The Mumbai branch of the Indian Patent Office covers Maharashtra, Madhya Pradesh, Goa and several union territories. A Mumbai startup files with and is examined by the Mumbai patent office.
What does patent filing cost for a Mumbai startup?
₹1,750 per application for individuals, DPIIT startups and small entities; ₹8,000 for large entities. Attorney drafting fees of ₹40,000-1,50,000 are usually the larger cost.
Can a Mumbai startup patent fintech or software?
Only partly. Section 3(k) excludes computer programs per se and business methods. A genuinely technical or hardware-coupled invention may qualify; most software and fintech IP relies on copyright and trademark.
How long does a patent take to grant in India?
Typically 3 to 5 years. The request for examination must be filed within 48 months; the First Examination Report follows 12-18 months after. DPIIT startups can use expedited examination.
Should a Mumbai startup file provisional or complete first?
Provisional first, in most cases. It locks the priority date cheaply and gives 12 months to file the complete specification — useful runway while the invention is finalised.
The honest patent advice is sometimes “do not file one”. Know the difference.
