## The answer, as recorded

Asked on 2026-09-12 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually approach it. "Patent search" splits into three tiers, and most small businesses should start at tier one and only pay when the stakes justify it.
> 
> ## Start free (DIY knockout search)
> 
> **1. Google Patents** - where I'd send almost anyone first. No signup, searches US/EP/WIPO/CN and more, and its ML-ish matching surfaces relevant hits even when your query is imprecise - which matters a lot when you don't know the right jargon for your own invention. Best single tool for citation mapping (following what a patent cites and what cites it).
> 
> **2. USPTO Patent Public Search** - the official one, built on PE2E, the same search tool USPTO examiners use for prior art. Clunkier than Google, but if you want to search the way the person who'll examine your application searches, this is it. Free.
> 
> **3. Espacenet (EPO)** - 150M+ documents, ~100 jurisdictions, with strong CPC classification, family, and legal-status data plus machine translation across 30+ languages. This is the one for "is this already patented somewhere outside the US, and is it still in force?"
> 
> **4. PATENTSCOPE (WIPO)** - ~124M documents, every PCT application published the day it's filed, and cross-lin
