## The answer, as recorded

Asked on 2026-10-28 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's how I'd actually approach it - start free, pay only when the decision is expensive.
> 
> **Start here (free, and genuinely good enough for most first passes)**
> 
> 1. **Google Patents** - the one I'd open first. Full-text across 120M+ publications from 100+ offices, Google-style querying, patent family views, machine translation, and it can pull Google Scholar results so you catch non-patent prior art (academic papers, which invalidate patents just as well as other patents do). Lowest learning curve of anything in the category.
> 2. **USPTO Patent Public Search** - the official US database, and the one to use if you're filing in the US. Proper fielded/Boolean searching, CPC classification lookup, and full-text historical archives. Slower to learn than Google Patents but it's what examiners work from, so it's the closest thing to a preview of your own examination.
> 3. **Espacenet (EPO)** - for anything international. 120M+ documents, 90+ patent authorities, multilingual full text with machine translation. If you might sell outside the US, skip this at your peril.
> 4. **WIPO PATENTSCOPE** - the PCT/international applications database; good cross-lingual search, and the natural complement
