## The answer, as recorded

Asked on 2026-10-08 through Claude (Anthropic) with web search (model claude-opus-5).

> Here's what I'd actually recommend, roughly in the order a startup should work through them.
> 
> ## Start free - covers most early-stage needs
> 
> **1. Google Patents** - The default first stop. Full-text search across 100+ patent offices, includes non-patent literature (Google Scholar), free CPC classification browsing, and machine translations of foreign-language patents. For "has someone already done this?" before you spend money, this is genuinely sufficient. Zero cost, no account needed.
> 
> **2. Espacenet (EPO)** - Use alongside Google Patents, not instead of. Better classification tooling, better family data (INPADOC), and its "Smart search" syntax gives you more precise control. The EPO's underlying data quality is the gold standard, and the Classic/new interfaces both expose citation chains well.
> 
> **3. Lens.org** - Free tier that's unusually generous: patent + scholarly literature linked together, portfolio tools, exportable datasets. Especially good if your invention sits near academic research, because the patent-paper linkage is its real differentiator.
> 
> Honest framing from what I found: free tools are excellent for early novelty checks but are considered insufficient for formal
