Google Patents** - Start here, always. Free, full-text search across ~87M+ patents from 17 offices, and crucially it searches non-patent literature (papers, product manuals) alongside patents, which is where a lot of startup-killing prior art actually lives. The semantic/AI search is now good enough that you can paste in a paragraph describing your invention and get useful hits. 90% of founders' early \"am I novel?\" questions get answered here. - [Google Patents](https://patents.google.com/), [comparison](https://casrai.org/compare/espacenet-vs-google-patents-vs-uspto-patent-public-search)\n\n**2.
