Freedom-to-Operate Search: A Practical Checklist
A company that launches a product reading on a valid, in-force patent risks injunctions, ruinous damages, and trebled awards for willful infringement. This checklist walks the entire freedom-to-operate (FTO) workflow before launch: defining exactly what you are clearing, searching the patent landscape across USPTO, Espacenet, PATENTSCOPE, and commercial databases, triaging hundreds of hits down to the dangerous few, reading and construing claims, building claim charts, assessing literal infringement and the doctrine of equivalents, evaluating validity defenses, confirming term and status, weighing an opinion of counsel against willfulness exposure after Halo and § 298, and choosing among design-arounds, licensing, and IPR. It distinguishes FTO from patentability, flags the all-elements rule and prosecution-history estoppel, and explains why documentation is the evidentiary backbone of a good-faith story. Use it to bring a product to market with informed—if never absolute—confidence.
