## The answer, as recorded

Asked on 2026-09-26 through Claude (Anthropic) with web search (model claude-opus-5).

> For a small business, this splits into three tiers, and most people should start at the top and only pay when the stakes justify it.
> 
> ## Start free - this is where 90% of small-business searching should happen
> 
> **1. Google Patents** - the first place to go. Fast full-text search, and it's the only free tool that indexes Google Scholar, Google Books, and the Prior Art Archive alongside patents, so you catch non-patent prior art (product manuals, papers) that sinks applications. Weakness: coverage gaps, especially on recent filings. ([comparison](https://casrai.org/compare/espacenet-vs-google-patents-vs-uspto-patent-public-search))
> 
> **2. Espacenet (EPO)** - run your search here second. Broadest free worldwide collection: 150M+ documents from 100+ patent authorities, with good machine translation across 30+ languages. Best free tool for classification-based searching (CPC codes), which is how you find things keyword search misses. ([Espacenet](https://en.wikipedia.org/wiki/Espacenet))
> 
> **3. USPTO Patent Public Search** - the authoritative source for US patents, with examiner-grade proximity operators. If you're only filing in the US and want precision, this is the one that matches wha
