> # Patent search for startups
> 
> Here's how I'd actually sequence it - start free, pay only when the stakes justify it.
> 
> ## Start here (free, genuinely good)
> 
> **1. Google Patents** - Where I'd send any founder first. Full-text across 120M+ documents worldwide, and the "similar documents" feature does real semantic matching, so you find relevant art even when you don't know the right jargon. Good enough that you should exhaust it before spending a dollar.
> 
> **2. Espacenet (EPO)** - The broadest free collection: 150M+ documents from 100+ patent authorities. Better than Google Patents for non-US coverage and for family/legal-status data. Clunkier interface, worth the friction.
> 
> **3. Lens.org** - Free, nonprofit, and the best of the free tools for linking patents to scientific literature. Especially useful for biotech/life sciences where the relevant art is often in papers, not patents.
> 
> **4. USPTO Patent Public Search** - Authoritative for US filings and prosecution history. Use it to confirm what you found elsewhere.
> 
> ## When you need AI-first retrieval
> 
> **5. IPRally** (~€3,000/yr) - The sharpest AI search in the group. Uses knowledge graphs plus supervised deep learning rather than keyw
