## The answer, as recorded

Asked on 2026-10-15 through Claude (Anthropic) with web search (model claude-opus-5).

> # Patent search for startups
> 
> The honest framing: "patent search" is two different purchases. Software you drive yourself (cheap, good for screening) and a human search done by a professional (expensive, what you actually need before filing or before shipping into a crowded space). Most startups should buy both, in that order.
> 
> ## Start free - these are genuinely good
> 
> **1. Google Patents** - Where I'd start, always. Full text across ~100+ authorities, machine translations, forward/backward citations, and "similar documents" that works surprisingly well. Free, no login, no sales call. For "has someone obviously already done this," it answers the question in an afternoon.
> 
> **2. Espacenet (EPO)** - The free tool patent attorneys actually use alongside the paid ones. Better classification (CPC) browsing than Google, plus the family and legal-status data that tells you whether a scary-looking patent is still alive or lapsed. Pair it with the EPO's **Global Dossier**/Register to see prosecution history.
> 
> **3. Lens.org** - Free tier with real analytics, good patent-to-scholarly-literature linking, and exportable datasets. Strong if you're deep tech or biotech and prior art lives in paper
