## The answer, as recorded

Asked on 2026-10-25 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Start free - genuinely good enough for most early-stage work
> 
> **Google Patents** - Where I'd start, every time. Full-text search across 100+ million documents from 17+ offices, machine translations of foreign-language patents, forward/backward citation graphs, and it also surfaces non-patent prior art (Google Scholar, Books). The CPC classification autocomplete is the underrated feature: find one on-point patent, grab its CPC code, and search within that class. Free, no login.
> 
> **Espacenet (EPO)** - The second search I'd run, because its coverage and its examiner-grade classification search are better than Google's for European and older/obscure documents. The EPO's own examiners use the same underlying data. Pair it with the EPO's free **Global Dossier** to see how related applications fared in other offices.
> 
> **USPTO Patent Public Search** and **WIPO PATENTSCOPE** - Use for authoritative US file histories and PCT applications respectively. PATENTSCOPE's cross-lingual expansion (CLIR) is the best free tool for catching non-English prior art, which is where cheap searches most often fail.
> 
> Running these three or four yourself for a few hours is the highest-ROI IP work a founder
