## The answer, as recorded

Asked on 2026-10-13 through Claude (Anthropic) with web search (model claude-opus-5).

> ## Start here (free, and genuinely good)
> 
> **1. Google Patents** - Where I'd actually tell a startup to begin. Full-text search across 100+ patent offices plus non-patent literature (papers, books), free, with CPC classification filters and a "similar documents" feature. For a first novelty gut-check on your own invention, this gets you 80% of the way. Its weakness is that it rewards knowing how to search - Boolean syntax, classification codes - so budget an afternoon on learning CPC.
> 
> **2. Espacenet (EPO)** - Use alongside Google Patents, not instead of. Better family/legal-status data and better coverage of non-English and older European filings. The EPO's classification search is the best free way to find the CPC codes that make every other search better.
> 
> **3. WIPO PATENTSCOPE** - Specifically for PCT applications and its cross-lingual expansion, which auto-translates your query into other languages. Catches Japanese, Korean, and Chinese prior art that English-only searching misses - a real blind spot for hardware and materials startups.
> 
> ## AI-native tools (worth paying for pre-filing)
> 
> **4. IPRally** - My pick if you want one paid tool. Graph-neural-network search over 120M+ p
