Freedom to operate search in India: when a company needs one and how it works

Owning a patent does not give you the right to sell your product. It only gives you the right to stop others from using your invention. If your product also uses a feature claimed in someone else's patent, you can infringe that patent even while holding your own. A freedom to operate search is how you find that out before the launch, not after the legal notice.

This guide explains what an FTO search is, when an Indian company needs one, how it is done and what the possible outcomes mean.

What freedom to operate means

Freedom to operate is the commercial freedom to make, use, sell or import a product or process in a particular country without infringing valid patent rights of others in that country.

Three points follow from that definition.

• Patents are territorial. An Indian patent can only be infringed in India. A US patent that was never filed in India does not stop you selling here, but it may stop your exports.
• Only claims matter. Infringement is judged against the claims of a patent, not its title, abstract or drawings. A patent with a frightening title can turn out to be narrow.
• Status matters. A patent that has expired, lapsed for non-payment of renewal fees or been revoked cannot be infringed. A patent lasts at most 20 years from its filing date in India, and many lapse earlier.

FTO is different from a patentability search, which asks whether your invention is new, and from due diligence, which checks a specific patent you plan to license. Our patent due diligence checklist covers that second job.

When an Indian company needs an FTO search

Not every product needs a formal FTO opinion. These are the moments when it is usually worth the cost:

• Before a launch in a crowded field such as pharmaceuticals, medical devices, agrochemicals, electronics or telecom.
• Before a large capital commitment, such as a new plant or tooling, that would be expensive to change.
• Before exporting, because each target country needs its own check.
• Before licensing a technology. A licence from a university or lab lets you use their patent. It does not clear the other patents your final product may touch.
• Before raising money or an acquisition, when investors or buyers ask about patent risk.
• When a competitor's patent is mentioned in a sales meeting, a tender or a notice.

How an FTO search is done, step by step

Step 1: Describe the product feature by feature

Break the product or process into its technical features: materials, composition ranges, steps, key components, software functions. The more precise the feature list, the better the search. A vague brief returns thousands of irrelevant documents.

Step 2: Fix the countries and the time window

List the countries where you will make, sell or import. For each one, you need patents that are in force or still pending. In practice that means documents filed roughly in the last 20 years, plus anything with a term extension where the country allows it. India does not grant patent term extensions.

Step 3: Search patents and published applications

Searchers use classification codes, keywords and the names of known competitors. Free public tools are a good start:

• InPASS, the Indian Patent Advanced Search System on the IP India website, for Indian applications and patents and their status.
• Espacenet from the European Patent Office, for worldwide coverage and patent family data.
• Google Patents and WIPO PATENTSCOPE, for full text and international (PCT) applications.

Pending applications matter too. In India an application is normally published 18 months after its priority date. From publication the applicant has rights as if a patent had been granted, but cannot sue until the patent is actually granted. A pending application that reads on your product is a future risk. Applications filed in the last 18 months are usually not visible yet, which is a blind spot every FTO has.

Step 4: Read the claims against your features

For each candidate, compare the independent claims with your feature list, element by element. If your product lacks even one element of a claim, it does not literally infringe that claim. Courts may also look at whether the product takes the substance of the invention, so borderline cases need an expert opinion.

Step 5: Check legal status

For each patent that could read on your product, confirm on the official register whether it is granted, pending, expired, lapsed or revoked, who owns it now, and whether renewal fees are paid. In India, a lapsed patent can sometimes be restored if the owner applies within 18 months of the lapse, so a recent lapse is not a permanent all-clear.

Step 6: Write it up and decide

The output is a report listing each relevant patent, the claims that matter, the risk level and a recommendation. For a high-stakes launch, ask for a written opinion from a registered patent agent or patent attorney.

What to do with the result

An FTO search rarely ends with "no risk at all". It ends with a short list of patents and a decision for each one.

1. Proceed. The patent does not cover your product, has expired or has lapsed. Keep the report on file.
2. Design around. Change the feature so it falls outside the claim. This is often the cheapest route if the claim is narrow and you find it early.
3. License. Approach the owner for a licence. Universities and public labs are often willing licensors, and a licence can come with know-how that speeds up your product. See how to license a technology from an Indian university or lab.
4. Challenge. In India anyone can file a pre-grant opposition after an application is published and before it is granted. Any interested person can file a post-grant opposition within one year from the date the grant is published. After that, revocation is possible under Section 64. Challenges cost time and money, so use them where the patent is weak and important to you.
5. Wait. If a key patent expires soon, timing the launch after expiry may be the simplest answer.

There is also a narrow statutory exemption. Section 107A of the Patents Act says that making, using or importing a patented invention solely for uses reasonably related to developing and submitting information required under any law is not infringement. This helps with regulatory testing, for example for generic medicines. It does not cover commercial sale.

What drives the cost and time

FTO fees vary widely, so ask for a fixed quote with a written scope. The main drivers are:

• the number of countries,
• how crowded the field is,
• how many product features are in scope,
• whether you need a search report only or a signed legal opinion.

A focused search for one product feature in India alone is much smaller than a full multi-country clearance for a complex device. Narrow the scope to the features that are new or valuable, and you cut both cost and noise.

Common mistakes

• Searching only for your own invention. That is a patentability search. It tells you nothing about other people's claims.
• Checking titles and abstracts only. Claims decide infringement.
• Treating a licence as clearance. It clears one patent, not the field.
• Doing it once. New patents are granted every week. Refresh the search before each major launch or export.
• Leaving it too late. An FTO done after tooling is ordered leaves you only expensive options.

If the search shows that a licence is the sensible route, it helps to know what is available. Zernyx Hub indexes about 6.5 lakh technologies from the last ten years, and its AI gives business insight on each one, including its commercial applications, so your team can look for licensable alternatives alongside the patents that worry you.

FAQ

Is an FTO search the same as a patent search?

No. A patentability search asks whether your invention is new. An FTO search asks whether your product would infringe patents that others hold and that are in force in the countries where you sell.

Do I need an FTO if I already have my own patent?

Yes, if the risk justifies it. Your patent lets you stop others. It does not give you the right to use features claimed in someone else's patent.

Can I do an FTO search myself?

You can run a first screen on InPASS, Espacenet or Google Patents to spot obvious risks. For a launch or investment decision, use a registered patent agent or attorney to read the claims and give an opinion.

Does a foreign patent stop me from selling in India?

Only if it has an Indian counterpart that is in force. Patents are territorial. A foreign patent can still block your exports to that country.

How long is an FTO search valid?

It reflects the patents visible on the day of the search. Applications filed in the last 18 months are usually unpublished, and new grants appear constantly, so refresh it before each major decision.
