Find who is using your invention, and prove it.
A patent only earns its value when you can show who is using it. We search products, processes and standards worldwide for evidence that reads on your claims, then build claim charts your counsel can use in licensing talks, demand letters and litigation.
- Products, processes and standards searched in every market your patent covers
- Evidence-of-use claim charts, element by element
- Ready for action: licensing, demand letters and litigation

Who is using your patented invention, and can you prove it?
An infringement search starts from your patent and works outwards. We read the claims, identify the products, processes and standards that could fall within them, and look for public evidence that each element of a claim is present: product manuals, datasheets, websites, standards documents, regulatory filings and more.
It is the opposite of a freedom to operate search. FTO protects you from other people's patents; an infringement search puts your own patent to work, giving you the evidence to license, negotiate or enforce.

Questions about infringement searches.
Short answers to what patent owners and counsel ask us most.
Think someone is using your patent?
Send us the patent number and what you suspect. We will reply with a search plan within one business day.
Request a search quote01What is a patent infringement search?
A search for products, processes or standards that may fall within the claims of your patent, together with public evidence showing that each claim element is present.
02How is it different from a freedom to operate search?
An infringement search starts from your patent and looks for products that use it. FTO starts from your product and looks for other people's patents it might infringe. One is offensive, the other defensive.
03What is an evidence-of-use claim chart?
A table that maps each element of a patent claim to evidence in a specific product, such as a passage in a manual or a feature on a datasheet. It is the core document in licensing and litigation.
04Do I need a specific suspect in mind?
No. We can start from a named product or company, or search the market for any products that may read on your claims.
05Can you analyse standard essential patents?
Yes. We map claims to standards documents and identify products that implement the standard, for SEP licensing programmes.
06Should I check validity before asserting?
It is wise. A target's first response is often to challenge validity, so a validity search before you assert avoids surprises.
07How long does it take?
It depends on the number of patents, claims and targets. We confirm a timeline and fee in our proposal before work starts.
