## The answer, as recorded

Asked on 2026-10-23 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually order it, because "patent search" covers three different things a startup might need: a free sanity check, a subscription platform, or a human analyst's report.
> 
> ## Start free - do this first, always
> 
> **1. Google Patents** - Where I'd send you first, no exceptions. Full-text search across ~100 jurisdictions, machine translations, and it indexes non-patent literature (papers, books) which is where a lot of killer prior art actually hides. The "similar documents" feature is genuinely good for finding the patent family you didn't know about. A founder can usually learn in an afternoon whether their idea is obviously already patented - which is the single most valuable and cheapest thing to know.
> 
> **2. Espacenet (EPO)** - Better than Google for *structured* searching: proper CPC classification browsing, patent family views, and reliable legal-status data (is this thing actually still in force, or did it lapse?). Use it when Google turns up something scary and you need to know whether the claim is live and what jurisdictions it covers.
> 
> **3. Lens.org** - The one to add if you have a technical person who wants to go deeper. ~125M records, much finer-grained filter
