What is a Clearance Search, or Freedom-to-Operate Search?

A clearance search — also called a freedom-to-operate (FTO) search — is one of the most important due diligence steps a company can take before launching a new product. It’s not the most common search, but when the stakes are high, it’s an essential investment. Here’s what it involves and when it makes sense.

What a Clearance Search Is

A clearance search is a search of issued and valid patents to determine whether your specific product or process would infringe any existing patent claims. Unlike a patentability search — which looks for prior art to evaluate whether your invention is new — a clearance search is focused entirely on risk: can you make, use, and sell your product without stepping on someone else’s patent rights?

The analysis is technically demanding. It requires reading and interpreting the claims of potentially many patents and mapping those claims against your specific product. Patent claims are written in precise legal language, and determining whether a product infringes requires careful claim-by-claim analysis. This is time-consuming work — which is why clearance searches are more expensive than a standard patentability search — but the cost is well justified in the right circumstances.

When a Clearance Search Makes Sense

A freedom-to-operate search is most valuable when:

• Significant capital is being invested in a new product. If you’re about to spend substantial money on tooling, manufacturing, marketing, or a product launch, knowing your patent risk upfront is essential. Discovering an infringement problem after launch is far more costly than identifying it in advance.
• You’re entering a patent-heavy industry. Some industries — medical devices, electronics, software, pharmaceuticals, and others — have dense patent landscapes. A clearance search helps you understand that landscape before you commit.
• You’ve received a cease and desist letter or a threat of infringement. If a competitor has accused you of infringement, a clearance search and infringement opinion gives you an informed basis for evaluating the threat and responding appropriately.
• You’re seeking investment or preparing for acquisition. Investors and acquirers often want assurance that a company’s products don’t carry unresolved patent infringement risk. An FTO opinion can be a key part of due diligence.
• Early in the product development phase. The earlier in the development process you conduct a clearance search, the more options you have. If a problematic patent is identified early, there may be time to design around it — modifying the product to avoid the patent’s claims. That option disappears once the product is finalized and launched.

What Happens if a Problem Patent is Found?

Finding a potentially problematic patent during a clearance search is not necessarily the end of the road. There are several strategies available depending on the circumstances:

• Design around: Modify the product to avoid the patent’s claims. This is why early searches are so valuable — there’s more flexibility to redesign before production.
• Validity challenge: If the patent appears to have been improperly granted — for example, because there is prior art the examiner didn’t consider — it may be possible to challenge its validity.
• Licensing: In some cases, obtaining a license from the patent holder is the most practical path forward.
• Non-infringement argument: A careful reading of the claims may reveal that your product doesn’t actually infringe, even if the patent initially appeared to be a concern.

Clearance Search vs. Infringement Opinion

These two terms are sometimes used interchangeably, but they’re slightly different. A clearance search is the research process — identifying and reviewing patents that could be relevant to your product. An infringement opinion is the formal legal analysis and written opinion that follows, setting out the attorney’s conclusions about whether your product infringes specific patents. For high-stakes situations, you want both.
