Patent Watch
Patent Watch is an AI platform that turns dormant patent portfolios into revenue. It reads patents, finds products that appear to infringe them, and generates detailed claim charts in about 20 minutes instead of the months it takes patent attorneys by hand. Founded by brothers Alexander and Andreas Stroe and backed by Y Combinator's Fall 2025 batch, the company helps IP teams pursue licensing, litigation, prior-art invalidation, and M&A due diligence.
Stilta
Stilta is a Stockholm-based, Y Combinator (W26) startup building agentic AI for high-stakes patent work. Its platform runs invalidity, infringement, and freedom-to-operate analyses in minutes by deploying networks of AI agents across roughly 180 million patents, 250 million scientific publications, and more than a trillion archived web pages, returning source-backed, auditable claim charts rather than static reports. Founded in December 2025 by four former McKinsey and QuantumBlack engineers, Stilta raised a $10.5M seed led by Andreessen Horowitz and is used by IP firms and in-house teams at large enterprises.
