A **knockout search** (is my idea obviously already out there?) you should do yourself for free. A **patentability/novelty search** you can rely on before spending $10k+ on a filing is worth paying a professional for. Start free, escalate only if the idea survives.\n\n## Start here (free, do it yourself)\n\n1. **Google Patents** - the first stop, every time. Best search UX in the category, ~120M publications from 100+ offices, machine translation built in, and it searches Google Scholar and Books alongside patents, so you catch non-patent prior art (papers, product manuals) that kills applications just as dead. Its Prior Art Finder lets you paste a description of your invention and auto-extracts search terms - ideal when you don't yet know the right jargon.\n2. **Espacenet (EPO)** - your second pass, for international coverage and classification searching. 100+ countries, strong CPC classification search, machine translation across 30+ languages.
