For most small businesses, the right answer is a two-step: do a free DIY screen yourself, then pay a human for a real search only if the idea survives.\n\n## Start here - free, and genuinely good\n\n**1. Google Patents** - the first stop for almost everyone. Full-text search across ~100+ jurisdictions, machine translation built in, CPC classification browsing, and the \"Similar Documents\" panel which is a surprisingly effective poor-man's semantic search. Free, no account. Use it to find the 10-20 closest references before you spend a dollar.\n\n**2. USPTO Patent Public Search** - the official US engine. Less pretty than Google, but it's the authoritative US record and it handles proper fielded/Boolean queries plus full prosecution history (file wrappers via Patent Center). Use it when you need to be sure about US status, claims as granted, or what an examiner cited.\n\n**3. Espacenet (EPO)** - best for non-US and international coverage, ~150M documents, strong classification tools and family/legal-status views. Pair it with Google Patents; between them you've covered most of what a cheap paid tool would give you. The EPO also runs **PATLIB centres** (32", "answer_truncated": true, "measurement": "One answer from one engine on one date.
