> The honest framing: "patent search" means two very different things, and the right answer depends on which you need. A **knockout search** (is my idea obviously already taken?) you should do yourself for free. A **novelty or freedom-to-operate search** that you'd stake money on belongs with a professional. Here's who I'd actually use, in order.

> **1. Google Patents** - The best starting point for almost everyone. 120M+ publications from 100+ offices, forgiving natural-language search (you don't need to know Boolean or classification codes), and it optionally folds in Google Scholar non-patent literature - which matters, because a journal paper or old product manual can kill your novelty just as dead as a patent. Spend your first few hours here.
> 
> **2. Espacenet (European Patent Office)** - Where you go once Google Patents gives you a hit worth chasing. Its strength is CPC classification search: find one relevant patent, grab its classification code, and pull everything else filed in that bucket. That's how you find the prior art that doesn't use your vocabulary. Also the right tool if you care about interna
