> ## Free tools - start here, in this order
> 
> **1. Google Patents** - Where I'd send anyone first. Full-text search across US, EPO, WIPO, CN and more, machine translations, no signup, and it pulls in non-patent literature via Google Scholar (which matters - prior art isn't only patents). Best interface by a wide margin. Weak spot: don't trust it for legal status (is the patent still in force?).
> 
> **2. USPTO Patent Public Search** - The authoritative source for US patents and published applications. Slower to learn than Google, but it's what examiners' data actually comes from, and it's the right place to confirm status and file history.
> 
> **3. Espacenet (EPO)** - 120M+ documents, the best patent-family tracking and CPC classification searching of the free tools. Use it once you've found one or two relevant patents and want to pull the classification code to find everything nearby. Interface is rigid; worth the hour.
> 
> **4. WIPO PATENTSCOPE** - For PCT/international filings if you're selling or manufacturing abroad.
> 
> **5. Lens.org** - Free, nonprofit, good for linking patents to scholarly literature and for basic analytics without a subscription.
