## The answer, as recorded

Asked on 2026-10-06 through Claude (Anthropic) with web search (model claude-opus-5).

> ## What I'd actually use, in order
> 
> **1. Google Patents - start here, always.** Free, full-text across 100+ patent offices plus non-patent literature, and its semantic "similar documents" feature is genuinely good. For the first question every startup has ("has someone already done this?"), it answers 80% of it in an afternoon. Zero reason to pay for anything before you've exhausted this. ([UpCounsel's roundup](https://upcounsel.com/patent-search-tools) puts it in the same top tier as the official office databases.)
> 
> **2. Espacenet (EPO) + WIPO PATENTSCOPE - free, and they catch what Google misses.** Espacenet's classification browser (CPC) is the best free way to find the *right* technology bucket rather than just keyword-matching; PATENTSCOPE covers PCT applications and has decent machine translation for CN/JP/KR families. Use both as a cross-check on Google Patents before you conclude anything is novel.
> 
> **3. USPTO Patent Public Search - free, for the one thing it's uniquely good at.** If you're filing in the US, this is the authoritative source for file histories and examiner-cited art. Reading the prosecution history of the two or three closest patents to your idea teaches you
