Patent Watch (PatentWatch.ai) is a Toronto-based, Y Combinator-backed (F25) legal-tech startup building AI for patent intelligence and infringement detection. Its platform interprets patents, maps them to competing products, and generates claim charts that show who is infringing and how, so IP teams can find licensing and litigation targets, send cease-and-desist letters, pursue counter-litigation, sell IP in wind-downs, and accelerate M&A diligence. It also runs AI invalidity and prior-art searches to help patents hold up in court. Founded in 2024 by Alexander and Andreas Stroe, the company raised a $2.8M seed round in April 2026. As of this profile Patent Watch is an early-stage product with a marketing site and login only, and no public developer, API, or documentation surface; this repo tracks it as an enrichment lead in the API Evangelist network.
