Freedom to operate vs. patentability: the two questions every founder confuses

Introduction

Patentability asks: can I get a patent on this? Freedom to operate asks: can I sell this without infringing someone else's patent? They're separate questions with separate answers, and a yes to one doesn't imply a yes to the other. Getting this wrong is how founders end up with a granted patent they can't commercialise.

‍

What is patentability?

Patentability is assessed against three criteria, applied by the examiner at the patent office.

• Novelty: nobody else has publicly disclosed this exact invention before your filing date, anywhere in the world, in any language.
• Inventive step: the invention would not have been obvious to a person skilled in your technical field, given what was already known.
• Industrial applicability: the invention can be made or used in some kind of industry, not pure abstract theory.

The question patentability asks is, in effect: if we look at everything that was public before your filing date, is your invention different enough? The assessment is backward-looking. It compares your invention against prior art.

‍

What is freedom to operate?

FTO is an entirely different question. It asks: given the patents other people currently hold, can I commercialise my product in my target markets without infringing any of them? The assessment is forward-looking. It compares your product against other people's existing rights.

FTO analysis does not care whether your invention is novel. It cares whether your product, as you intend to make and sell it, falls within the claims of someone else's in-force patent in a country where you want to operate. Two products can both be patentable and both infringe each other. Both can infringe a third party's earlier patent without anyone knowing about it.

‍

Why a yes to one is not a yes to the other

A concrete example. You invent a new kind of bicycle brake that combines two existing techniques in a specific, novel way. The patent office agrees: nobody has combined them like this before. You get a granted patent on your specific combination. Patentable: yes.

Now consider whether you can sell the brake. One of the two existing techniques you combined is itself still under patent protection, owned by a large components manufacturer. To make your brake, you necessarily practise their patent. When you try to sell, they sue. Freedom to operate: no.

Your granted patent gives you the right to stop others from practising your specific combination. It does not give you the right to practise the underlying components. Those are two different legal powers, often held by different companies at the same time.

‍

What does each analysis actually cost?

Patentability searches are relatively cheap. The examiner at the EPO does one as part of the filing process. A pre-filing patentability check of the kind ptntpwr offers takes under two minutes and gives a first signal at zero cost. A deeper patentability opinion from an attorney typically runs a few hundred to a few thousand euros.

FTO opinions are more expensive. A proper FTO searches for all in-force patents in your target markets that might cover your product, reads the claims, and analyses whether your product reads onto them. For a single product in a handful of European markets, this is usually several thousand to low five figures. For a global FTO on a complex product, it can run much higher.

The cost asymmetry is not arbitrary. Patentability is narrow: it compares one invention to the prior art. FTO is broad: it compares one product to potentially thousands of in-force patents across every country you care about.

‍

When should you do which?

Most early-stage startups prioritise patentability before FTO, and that is usually correct.

• Before filing: run a patentability check. You need to know whether filing is worth the money.
• Before launching in a market: run an FTO for that market. You need to know whether selling there will expose you to infringement litigation.
• Before a major investment round: Series B investors increasingly ask for FTO opinions. Earlier-stage investors usually do not.
• Before a partnership or licensing deal: the counterparty will often demand an FTO.

One situation where FTO comes first: if you are building in a crowded patent landscape, such as wireless standards, certain medical devices, or certain software standards. In those cases, a quick FTO screen before you invest in R&D can save years of work on a product you could never commercialise.

‍

The question founders must ask their attorney

When you talk to a patent attorney, be precise about which question you need answered. "Do I have a patent problem?" is too vague. Better:

• "Is this invention likely to be patentable?" for patentability.
• "If I launch this product in Germany next quarter, am I likely to infringe anyone?" for FTO.
• "If I patent this, could I still get sued for selling it?" for both.

A good patent attorney will answer whichever question you ask. A great one will tell you, unprompted, which of the three you actually meant.

‍

Conclusion

Patentability is about getting a right. FTO is about not violating someone else's right. Both matter. Neither answers the other. The founders who understand this distinction file earlier, budget better, and negotiate harder, because they know exactly which legal question is in front of them at any given moment.

Start with the patentability question. It's the cheaper of the two, it's the one your priority date depends on, and it's the one ptntpwr is built to answer.

Frequently asked questions

‍

What is the difference between patentability and freedom to operate?

Patentability asks whether you can obtain a patent on your invention. It is assessed by comparing your invention against prior art. Freedom to operate asks whether you can sell your product without infringing someone else's existing patent. It is assessed by comparing your product against in-force patents in your target markets. A yes to one does not imply a yes to the other; both questions require separate analysis.

‍

Can a product infringe a patent even if it is itself patentable?

Yes. A product can be novel and inventive enough to receive its own patent, while simultaneously infringing an earlier patent held by a third party. This happens when the product combines existing patented elements in a new way. The new combination may be patentable, but practising the underlying components still requires freedom to operate. Patents give you rights against others; they do not give you the right to use everything in your own product.

‍

How much does a freedom to operate search cost?

A freedom to operate opinion is typically more expensive than a patentability assessment. For a single product in a handful of European markets, costs usually range from several thousand euros to low five figures. For global coverage or complex products in crowded patent landscapes, costs can be significantly higher. The analysis involves searching all in-force patents in target markets and assessing whether the product's specific features fall within any of their claims.

‍

When should a startup commission a freedom to operate analysis?

The most important triggers are: before launching a product in a new market, before a major investment round where investors may require it, and before entering a licensing or partnership deal where the counterparty will demand it. For startups building in crowded patent landscapes such as wireless standards, medical devices, or certain software areas, an early FTO screen before significant R&D investment can prevent years of work on a product that cannot be commercialised.
