About Patent Watch
Summary
Patent Watch builds AI software that automates patent infringement detection for companies and legal teams. It reads patents, surfaces competing products, and produces claim charts that map exactly which claims a product infringes and how, replacing the manual attorney work that typically costs tens of thousands of dollars per engagement. Teams use it to pursue licensing targets, send cease-and-desist letters, counter litigation, support M&A diligence, and run prior-art and invalidity searches.
Business model
SaaS subscription, with access starting via a self-serve demo booking flow
Go-to-market
Patent Watch targets corporate IP teams and law firms that hold granted patent portfolios; buyers can book a demo and get started through the product website without a formal sales process.

AI for detecting patent infringements
We automate patent infringement detection. Our software interprets patents, identifies competing products, and generates claim charts showing who’s infringing and how. Teams use us to: - Find licensing and litigation targets - Send cease-and-desist letters - Find counter litigation - Sell IP in wind-downs - Accelerate M&A diligence We also run AI invalidity and prior-art searches to help your patents hold up in court. Companies spend up to $50k to file and maintain a single patent over its lifetime, but once it's granted, they let it collect dust. With Patent Watch, you can start turning your patent portfolio into revenue in 10 minutes.
