A freedom to operate search answers one question: can you make, use, sell, or import this product in these countries without infringing somebody else's live patent?
That is a different question from "is my invention new enough to patent?" A patentability search looks backward at everything ever published, because anything published can defeat novelty, even a lapsed patent from 1974. A freedom to operate search, usually shortened to FTO, looks at rights that are alive and enforceable right now in the places you plan to trade. An expired patent cannot stop you. A granted patent in force in Germany can stop you selling in Germany.
This post explains what the search covers, what you actually receive at the end of it, how long it takes, and when it is worth commissioning.
What the search covers
Three things define the scope, and they are worth settling before any searching starts.
Your markets. Patents are national rights. A search is only as wide as the list of countries you give us. That list should include everywhere you will sell, plus everywhere you will manufacture, assemble, or import through. A factory in one country and customers in another means two sets of rights to clear, not one.
Your product's features. FTO is claim driven, not concept driven. We break the product into the features it must have to work and to sell, then test each of those features against the claims of live patents. A feature you could drop tomorrow is a low priority. A feature the whole product depends on is where the searching effort goes.
Live rights only. We look at granted patents that are in force in your markets, plus published applications that could still grant before or shortly after your launch. Patent families matter here. One invention is often filed as an international application and then split into separate national patents that grant at different times, with different claim wording in each country. Following the family is how you avoid clearing the United States and walking into a European grant with broader claims.
Utility models are included where the market has them, for example Japan, China, and Germany, because they are enforceable even though they are not examined the same way.
What you receive
The deliverable is a written report, not a list of search hits. A useful FTO report contains:
- The scope statement. The countries searched, the product features tested, the databases used, the classification codes and search strings, and the date the search was run. This is what makes the work repeatable and auditable later.
- A hit list with the noise removed. Every family that came back, with the ones that clearly do not read on your product screened out and a one line reason why.
- Claim charts for the families that matter. The independent claim broken into its elements in one column, your product feature in the other, and an element by element read. This is the core of the work and the part an investor or an acquirer will ask to see.
- A risk read per family, not one score for the whole product. See the next section.
- Status and expiry data. Whether each patent is in force, which countries it is in force in, when it expires, whether renewal fees have been paid, and whether it is under opposition or has been amended during prosecution.
- Options. For each item that reads on your product: design around routes, non infringement arguments, invalidity angles worth investigating, licensing contacts, or a recommendation to sequence that market later.
Where you need it for a board, a lender, or a due diligence room, that report can be issued as a formal written opinion signed by a patent attorney. An opinion costs more and takes longer than a search report, because the attorney has to reach and defend a conclusion rather than present findings.
How we grade risk
Three tiers keep the conversation useful for people who are not patent lawyers.
Red. A granted patent, in force in a market you are launching in, whose independent claim reads on a feature your product cannot ship without. This needs a decision before tooling is cut.
Amber. A pending application with claims that could be amended to cover you, or a granted claim where there is a genuine non infringement argument that has not been tested. This needs monitoring and usually a short written analysis.
Green. Expired, lapsed, never filed in your market, or claims that plainly do not read on your product. Documented and revisited on a schedule.
Grading per family rather than per product matters, because the answer to a red item is almost never "stop". It is usually change one feature, license, or launch that market later.
How long it takes
For a single product in three to five countries, expect roughly:
- One to two weeks for the search and the first pass hit list.
- Another one to two weeks for claim charts and analysis on the families that survive screening.
- Longer where a formal written opinion is required, or where the art is crowded and the hit list runs to hundreds of families.
Crowded fields such as wireless, medical devices, and battery chemistry take longer than a mechanical consumer product, because there is simply more to read. If you are working to a launch date, start the search at least a quarter before the point where a design change becomes expensive.
When it is worth doing
The value of an FTO search is highest at the moment when acting on the answer is still cheap. In practice that means four points:
- Before you commit to tooling or manufacturing. Changing a feature in CAD costs a meeting. Changing it after the mold is cut costs the mold.
- Before you launch in a new country. A product cleared for the United States is not cleared for Europe or China. Each new market is a new search, usually a much smaller one because the product is already broken down into claim elements.
- Before you raise or sell. Investors and acquirers ask what patent risk sits under the product. An FTO report with dated claim charts answers that in one document. Having no answer at all is what slows a deal.
- Before you sign a supply or licensing deal that includes an indemnity. If you are promising to cover somebody else's infringement exposure, you want to know what you are promising.
For a product still being sketched, a lighter landscape scan is usually the better spend, and the full FTO comes later once the feature set is settled.
What an FTO search cannot tell you
Being straight about the limits is part of the deliverable.
- Patent applications are secret for a period. Applications generally publish 18 months after their earliest filing date. Anything filed in the last 18 months is invisible to any searcher, anywhere. This is why FTO is repeated, not done once.
- Pending claims can change. A claim you cleared today can be amended tomorrow, within limits. Amber items need watching.
- A search is not a guarantee of non infringement. It is a reasoned assessment on the records available on a given date. That is why the date and the scope statement are in the report.
- It covers patents. Trademarks, registered designs, and copyright are separate clearance exercises. If you are also launching a brand, run a name check alongside the FTO with a free trademark check.
What we need from you to start
The search moves faster when the first email contains:
- A short product description, plus drawings, a spec sheet, or CAD if you have them.
- The features you believe are essential, in your own words. We will translate them into claim language.
- The countries you will sell in, manufacture in, and import through, for the next one to three years.
- Your launch date and any tooling or certification milestones before it.
- Competitors you already know about, and any patent numbers anyone has already waved at you.
If you have received a letter alleging infringement, say so at the outset. That changes the shape of the work from clearance to response.
What happens when the search finds something
Most searches on a real product find at least one item worth talking about. The usual routes out, in rough order of cost:
- Design around. Change the feature so the claim no longer reads on it. Cheapest by a wide margin when the search happens early.
- Non infringement position. Document, with the claim chart and the prosecution history, why your product falls outside the claim as granted.
- Invalidity. Look for prior art that undermines the claim. This is a real option, but it is litigation grade work and is priced that way.
- License. Sometimes the fastest path, particularly where the owner is not a competitor.
- Sequence. Launch in the clear markets now and revisit the blocked one when the patent expires or lapses.
Our patent team scopes, runs, and reports FTO searches, and can issue a formal written opinion where you need one for a board or a data room. Start at freedom to operate searches, or see patent filing if you also want to protect your own design.
