FTO vs Patentability Search in India: Two Different Questions

Published on: October 6, 2026
Last updated: 12 July 2026

A patentability search and a freedom to operate (FTO) search look alike, but they ask opposite questions. Here is how each works in India, who needs which, and where tools fit.

Explainer · Patent Searches

A founder files a patent, gets it granted, and then learns that selling the product still infringes somebody else's patent. The reverse also happens: a team clears a product as "safe" and then finds that nobody can patent it. Both mistakes come from using the wrong search for the question. A patentability search asks whether your invention can be protected. An FTO search asks whether you can sell your product without being stopped. This page defines each one, side by side, for India.

The short answer
  • Patentability search: asks if your invention is new, inventive and allowed. It reads old disclosures from anywhere in the world.
  • FTO search: asks if your product infringes a live patent. It reads the claims of in force patents in the country where you sell.
  • Order: patentability before you file. FTO before you launch, and again at big milestones.
  • Neither replaces the other, and neither replaces a patent attorney's opinion.

01Why the two searches get mixed up

People mix up these two searches because both involve reading patents and both are called "prior art searches" in casual talk. The tools look the same. The question behind them is not.

A patent is not a licence to sell

A patent gives its owner the right to stop others. It does not give the owner the right to practise the invention. Under Section 48 of the Patents Act, 1970, the patentee can prevent others from making, using, offering for sale, selling or importing the patented product or process. Your own patent does not remove another person's earlier patent from the road.

Patent search and FTO use different documents

A patentability search looks at everything published before your filing date, in any country, in any language, including papers and products. An FTO search looks at a much smaller set: patents that are still alive and in force in the country where you will sell. One set is wide and old. The other is narrow and current.

A patentability search asks whether the world already knows your idea. An FTO search asks whether someone else already owns the right to stop your product.

Not legal advice

Both searches feed a legal opinion. They are inputs for a patent attorney, not a replacement for one. This page explains the difference. It does not tell you what to file or launch.

02The two claim-level analyses, side by side

The core difference is whose claims you read, and which way you compare. In a patentability search, you compare your claims against old disclosures. In an FTO search, you compare your product against other people's claims.

PointPatentability searchFTO search
Main questionIs my invention new, inventive and not excluded?Will my product infringe a live patent?
Whose claims are readYour own draft claimsClaims of other people's patents and published applications
What you compare againstPrior art: patents, papers, products, public useIn force patents and pending applications in the target country
Time cutEverything published before your filing or priority dateToday and the patent term ahead (patents last 20 years from filing)
TerritoryWorldwide, because novelty is absolute under Indian lawCountry by country where you make or sell
Legal hooks in IndiaSections 2(1)(j), 2(1)(ja), 2(1)(l), 3 and 4 of the Patents ActSection 48 (rights of patentee) and infringement and revocation proceedings
ResultGo or no go on filing, plus how to draft claimsClear, redesign, license, challenge, or do not launch
Who decides in the endThe Patent Office examiner, on examinationA court, if you are sued
Typical timingBefore filing a patent applicationBefore launch, funding or a large production run

Notice that neither search can answer the other's question. A clean FTO result does not mean your invention is new. A strong novelty result does not mean the road is clear.

03Patentability search in India

A patentability search tests whether your invention is likely to pass examination at the Indian Patent Office. It is done before you file, when you can still change the claims.

What it checks

  • Novelty: has the same invention been disclosed anywhere in the world before your date?
  • Inventive step: would the idea be obvious to a skilled person, given what is already known? This is defined in Section 2(1)(ja).
  • Industrial applicability: can it be made or used in industry?
  • Excluded subject matter: does it fall under Section 3 or Section 4, such as a mere discovery, a mathematical or business method, or a computer program per se? This is a frequent surprise for software founders.

What the Indian system itself does

The Patent Office runs its own search during examination, and an application can face a pre-grant opposition under Section 25(1) from any person. A patentability search simply moves that scrutiny earlier, so you find the problem before the examiner does. WIPO and the Indian Patent Office both publish searchable databases that help here.

What it cannot tell you

It does not tell you whether you can sell the product. Many patentable products sit inside someone else's broader patent.

04FTO search in India

An FTO search tests whether making and selling a specific product, in a specific country, would infringe another party's in force patent. "Freedom to operate" is a business term, not a section of the Patents Act. The legal question underneath is infringement under the rights in Section 48.

How it is done

  1. Fix the product: write down exactly what you will make or sell, feature by feature, and where.
  2. Collect live patents: find granted patents and pending applications in India that touch those features. Check status, expiry and any assignment.
  3. Read the claims, not the abstract: infringement is judged on the claims. Map each feature of your product against each claim element.
  4. Check validity and history: look at opposition, revocation, and litigation history on the patents that matter.
  5. Decide the route: proceed, redesign, license, wait for expiry, or challenge the patent.

The court side of FTO

FTO is not only a document exercise. If a patent is a risk, the next questions are how courts in India have treated it. Has the owner sued before? Which court and which interim orders? Has anyone attacked its validity by revocation under Section 64, or raised invalidity as a defence? Those answers sit in court records and judgments, not in the patent file alone. In Delhi, patent suits are handled by the Delhi High Court IP Division, and its orders are on the court's own site.

For the registry and journal side of IP monitoring in general, see our guide to trademark hearing tracking in India. That page covers trademarks, a different right with a different process.

05Which one do you need, and when

You usually need both, in this order: patentability first, FTO later and again before launch. Here is a simple guide.

  • You have a new idea and have not filed: patentability search. If you publish or sell first, you may destroy your own novelty. See prior publication and design novelty in India for how earlier disclosure can hurt a design right.
  • You are about to launch a product: FTO search, even if you hold your own patent.
  • An investor or acquirer is doing diligence: expect to be asked for FTO. A patent portfolio alone does not answer it.
  • You received a notice or a rival filed a suit: a targeted FTO and validity review of that one patent, fast.
  • You plan to sell outside India: FTO is country specific. An India result says nothing about the US or Europe.

An FTO result also ages. New applications are published, patents lapse, and your product changes. Treat an FTO as a dated snapshot and refresh it before big milestones.

06Common mistakes

Using a novelty result as an FTO result

A search that found nothing close to your claims says your idea looks new. It says nothing about whether a broader earlier patent covers your product.

Reading titles and abstracts only

Claims define the legal scope. Two patents with similar titles can have very different claims, so claim level reading is the step that matters in both searches.

Forgetting pending applications

An unpublished or pending application can become an in force patent later. Flag them and watch them.

Ignoring status and ownership

A patent may have lapsed for non-payment of renewal fees, been assigned, or been narrowed. Always check the current register status on the Indian Patent Office public search.

Treating search tools as a final answer

Software finds candidates. A patent attorney reads the claims and gives the opinion. No search tool, including any named on this page, replaces that step.

07Where Claw fits

Claw is an all-in-one legaltech platform for Indian advocates, law firms, and corporate legal teams, combining AI-based case search, an AI legal assistant (Legal GPT), case management, and compliance automation across all Indian courts and tribunals.

An FTO review is not finished on the patent file alone, because the real risk shows up in how a patent has been enforced or attacked in court. Claw covers that court side. It tracks cases, orders and hearings across 9,102 courts, benches and forums, searches 30 crore+ judgments in under 5 seconds, and reaches Supreme Court judgments from 1950 and High Court judgments from 1990. So you can check whether a patent owner has sued before, what interim orders followed, and whether validity was challenged by revocation.

Claw does not use customer documents to train AI models. Create a FREE Claw account to run that court-side check and track a live patent matter by party or advocate name. To search the wider body of law, see case search across Indian courts.

09Frequently asked questions

What is the difference between a patentability search and an FTO search?

A patentability search checks whether your invention is new, inventive and allowed, by comparing your claims to prior art. An FTO search checks whether your product infringes someone else's live patent, by comparing your product to their claims. They ask opposite questions and use different document sets.

If I own a patent, do I still need an FTO search?

Yes. A patent lets you stop others. It does not let you sell if your product also falls within an earlier patent held by someone else. An FTO search checks that risk before launch.

Is FTO a legal term in the Indian Patents Act?

No. Freedom to operate is a business term. The legal question behind it is infringement, linked to the rights of the patentee in Section 48 of the Patents Act, 1970. Confirm section references on the India Code site.

Is an FTO search valid worldwide?

No. Patents are national rights, so an FTO search is done country by country. An India result does not cover the US, Europe or any other market.

Can software do an FTO search for me?

Software can find and organise candidate patents, track status, and surface court history. A patent attorney still needs to read the claims and give the opinion. Specialist patent analytics tools go deepest on worldwide prior art, while Claw helps with Indian registry tracking and court records in one place.

How current should an FTO result be?

Treat it as a dated snapshot. New applications are published and patents change status, so refresh it before launch, funding rounds and major product changes.
