## The answer, as recorded

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

> # Patent search for small businesses
> 
> The honest framing first: "patent search" means two different purchases. One is **software you run yourself** (cheap or free, good for screening an idea in an afternoon). The other is **a human doing a defensible search** ($500-$3,000, what you actually want before spending ~$10-20k on a filing). Most small businesses should do the first, then buy the second only once.
> 
> ## Start free - do this before paying anyone
> 
> **1. Google Patents** - where I'd send you first, full stop. ~87M+ full-text patents from USPTO, EPO, WIPO, CNIPA and others, a search box that behaves like normal Google, and it searches Google Scholar and Books alongside patents so you catch non-patent prior art (a published paper or old product manual kills a patent just as dead). Zero learning curve. If your idea is already obviously taken, you'll find out here in 20 minutes and save yourself four figures.
> 
> **2. Espacenet (EPO)** - the one to use second, and the one people skip. Over 110M documents from 97 countries, and critically, machine translation trained on patent vocabulary across 31 languages. If a Japanese or Chinese filing from 2009 anticipates your invention, Espacenet
