Bengaluru’s deep-tech cluster — semiconductor design, robotics, space-tech, AI hardware, climate tech — runs on inventions that are genuinely novel. That novelty is exactly what a patent protects, and exactly what a competitor or a fast-following incumbent will replicate if it is left unprotected. For a deep-tech founder in Bengaluru, the patent is not paperwork. It is the moat.
Patents in India are governed by the Patents Act, 1970. For any business based in Karnataka, applications are filed with and examined by the Chennai branch of the Indian Patent Office. This guide covers what a Bengaluru deep-tech startup needs to know: what is patentable, why provisional filing is the default, what it costs, and the timeline from filing to grant.
In deep tech, the invention is the company. An unprotected invention is a company anyone can copy.
Why Bengaluru deep-tech files patents early
A patent does three things for a deep-tech startup. It creates a defensible moat against fast followers. It is a balance-sheet asset investors actively value — deep-tech VCs in Bengaluru ask about the patent position in the first meeting. And it secures a priority date, which in a fast-moving field is the difference between owning an invention and watching someone else own it.
The risk specific to Bengaluru is disclosure. The city runs on demo days, accelerator showcases, technical conferences and investor pitches — every one of which is a public disclosure under Section 25 if it happens before filing. A patent must be filed before the invention is shown.
The Chennai patent office serves Bengaluru
The Indian Patent Office operates four branches — Delhi, Mumbai, Kolkata and Chennai. Karnataka falls under the Chennai branch. A Bengaluru deep-tech startup files online; the Chennai office examines the application, issues the First Examination Report, and conducts any hearing — in person or by video conference.
Jurisdiction does not change the process or the fees, which are uniform nationwide. It only determines which examiners review your specification and where any hearing is listed.
What is patentable — and what Section 3 excludes
To be patentable in India, an invention must be novel, involve an inventive step, and be capable of industrial application. Section 3 then carves out exclusions that catch a lot of Bengaluru startups by surprise:
- Section 3(k) — computer programs per se, mathematical methods, business methods, and algorithms are not patentable. Software with a technical effect or tied to hardware may still qualify.
- Section 3(d) — mere new forms of known substances without enhanced efficacy (relevant to materials and chem-tech).
- Section 3(j) — plants, animals, and essentially biological processes.
For a pure-software Bengaluru startup, this means the product is usually protected by copyright on the source code and trademark on the brand, with patents reserved for genuinely hardware-coupled or technically inventive components. A patentability search before drafting confirms eligibility and prior art.
Provisional first: the deep-tech default
For most Bengaluru deep-tech startups, the right first move is a provisional specification under Section 9. It describes the invention without requiring full claims, locks the priority date immediately, and gives 12 months to file the complete specification. That 12 months is runway — to keep iterating the hardware, to run more experiments, to raise the round that funds the full patent drafting.
Costs, RFE, and the grant timeline
The government fee is ₹1,750 per application for individuals, DPIIT-recognised startups and small entities — most Bengaluru deep-tech startups qualify. Large entities pay ₹8,000. The larger real cost is attorney drafting: a deep-tech complete specification runs ₹40,000-1,50,000 depending on complexity.
The timeline: provisional filed, complete within 12 months, request for examination (Form 18) within 48 months of priority, First Examination Report 12-18 months after that, response within 6 months, then grant. Total: 3 to 5 years. Provisional filing and complete specification drafting are distinct workstreams — plan the complete to start at month 6, not month 11.

- Disclosing before filing. A demo day or conference talk before the provisional is filed can destroy novelty.
- Assuming software is patentable. Section 3(k) excludes programs per se. Check eligibility before spending on drafting.
- Narrow provisional. A prototype-only provisional cannot support a broad complete specification.
- Missing the 48-month RFE. No request for examination means the application lapses. Docket it.
- Skipping the prior-art search. Filing into known prior art wastes the drafting fee.
The provisional is cheap. The disclosure that beats it to the office is not.
People also ask
Can a Bengaluru startup file a patent without a working product?
Yes. A provisional specification needs only a sufficient description of the invention, not a finished product. Many Bengaluru deep-tech startups file provisional at the prototype or even detailed-design stage.
Does a DPIIT startup get faster patent examination?
Yes. DPIIT-recognised startups are eligible for expedited examination, which can compress the grant timeline significantly compared with the ordinary queue.
Is a PCT application worth it for a Bengaluru startup?
If international markets are on the roadmap, yes. Filing PCT within 12 months of the Indian provisional preserves the Indian priority date across 150+ countries — useful for deep tech selling globally.
Who owns a patent invented by Bengaluru employees?
The inventors are named, but ownership is assigned to the company through employment agreements and a Form 1 assignment. Ensure every technical hire has signed an IP assignment clause.
Frequently asked questions
Which patent office handles Bengaluru applications?
Patent applications from Karnataka are filed with and examined by the Chennai branch of the Indian Patent Office. Filing is online; the Chennai office handles examination and any hearings for Bengaluru applicants.
Can a Bengaluru startup patent its software?
Only partly. Section 3(k) of the Patents Act, 1970 excludes computer programs per se. Software with a demonstrable technical effect, or hardware-coupled inventions, can be patentable. Pure algorithms and business methods are not.
What does patent filing cost for a Bengaluru 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 for a deep-tech specification.
How long does an Indian patent take to grant?
Typically 3 to 5 years from filing to grant. A request for examination must be filed within 48 months, and the First Examination Report usually follows 12-18 months after that request.
Should a Bengaluru deep-tech startup file provisional or complete?
Provisional first, in most cases. It locks the priority date cheaply while the invention is still iterating, and gives 12 months to file the complete specification — useful runway for a deep-tech team.
File the provisional, then show the demo. Never the other way round.
