## The answer, as recorded

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

> ## What I'd actually recommend, in order
> 
> **1. Google Patents** - free, and genuinely the best first stop. Full-text across ~100+ offices, machine translations, "Similar documents," and CPC classification browsing. For the "has someone already done this?" question that 90% of startups are actually asking, this plus an hour of your time answers it. Don't pay for anything until you've exhausted it.
> 
> **2. Espacenet (EPO)** - free, and better than Google Patents for two specific things: the classification search tree, and family/legal-status data (where a patent is actually in force). Pair it with the EPO's free **Global Dossier** to read examiner correspondence on competitor patents - that tells you what prior art examiners already found, which is often more useful than your own search.
> 
> **3. Lens.org** - free tier is strong, paid tiers are transparently priced (unusual in this market) and sized for small teams. Links patents to scholarly literature, which matters a lot if you're a deep-tech or bio startup where the killer prior art is a paper, not a patent. Also gives you saveable collections and basic analytics without an enterprise contract.
> 
> **4. PQAI (projectpq.ai)** - free, open
