What is an evidence of use search?
An evidence of use (EOU) search seeks to identify evidence of the commercial use of a particular technology or patented invention.
It is also called a patent infringement search or “patent-to-product mapping” as the process involves correlating patent claims with specific features or components in commercial products or services.
The process effectively identifies potential patent infringement or areas for licensing opportunities.
