One is **software you run yourself** (cheap or free, good for screening an idea in an afternoon). The other is **a human doing a defensible search** ($500-$3,000, what you actually want before spending ~$10-20k on a filing). Most small businesses should do the first, then buy the second only once.\n\n## Start free - do this before paying anyone\n\n**1. Google Patents** - where I'd send you first, full stop. ~87M+ full-text patents from USPTO, EPO, WIPO, CNIPA and others, a search box that behaves like normal Google, and it searches Google Scholar and Books alongside patents so you catch non-patent prior art (a published paper or old product manual kills a patent just as dead). Zero learning curve. If your idea is already obviously taken, you'll find out here in 20 minutes and save yourself four figures.\n\n**2. Espacenet (EPO)** - the one to use second, and the one people skip. Over 110M documents from 97 countries, and critically, machine translation trained on patent vocabulary across 31 languages.
