The answer, as recorded

Here's how I'd actually approach it - start free, pay only when the decision is expensive. **Start here (free, and genuinely good enough for most first passes)** 1. **Google Patents** - the one I'd open first. Full-text across 120M+ publications from 100+ offices, Google-style querying, patent family views, machine translation, and it can pull Google Scholar results so you catch non-patent prior art (academic papers, which invalidate patents just as well as other patents do). Lowest learning curve of anything in the category. 2. **USPTO Patent Public Search** - the official US database, and the one to use if you're filing in the US. Proper fielded/Boolean searching, CPC classification lookup, and full-text historical archives. Slower to learn than Google Patents but it's what examiners work from, so it's the closest thing to a preview of your own examination. 3. **Espacenet (EPO)** - for anything international. 120M+ documents, 90+ patent authorities, multilingual full text with machine translation. If you might sell outside the US, skip this at your peril. 4. **WIPO PATENTSCOPE** - the PCT/international applications database; good cross-lingual search, and the natural complement to Espacenet for coverage gaps. 5. **Lens.org** - a nonprofit, freemium platform that links patents to scholarly literature and sequences. Worth knowing because its incentives aren't a sales funnel, and the free tier is substantial. A real search means running the same concept across at least two or three of these, not one - coverage and full-text depth differ meaningfully by office. **Free human help** 6. **USPTO Patent and Trademark Resource Centers (PTRCs)** - a nationwide network of public/academic libraries where trained librarians walk you through search strategy and classification for free, in English and Spanish. Massively underused by small businesses. Caveat: they're not attorneys and can't give legal advice or help fill out your application. 7. **USPTO Pro Bono / Pro Se assistance programs** - free or reduced-cost legal help if you're income-qualified; worth checking before paying anyone. **When to pay** 8. **A flat-fee patentability search from a patent attorney or search firm** - my default paid recommendation for a small business, because you get a written patentability opinion, not just a document dump. Expect roughly $1,000-$1,250 for a simple invention, $1,500-$2,000 moderately complex, and $2,000-$3,000 for software or crowded fields. Insist on a *flat* fee with defined scope. The economics are simple: a few thousand spent finding killer prior art now beats finding it after you've paid for drafting, filing, and prosecution. 9. **PatSnap** - the paid platform I'd name for a small business that searches regularly rather than once: broad global coverage (US/EP/JP/KR/CN), analytics, citation mapping, easy export, and they do sell to small businesses. Pricing isn't published - you'll need a quote, so negotiate. 10. **PatSeer, Questel Orbit Intelligence, or Clarivate Derwent Innovation** - the professional tier. Strong analytics and structured search workflows, but these are built and priced for IP departments. I'd only point a small business here if patents are core to your business model. My honest recommendation for a typical small business: spend a weekend on Google Patents plus Espacenet, book a session with your local PTRC, and *then* buy one flat-fee attorney search before you file. Don't subscribe to a commercial platform for a one-off invention. One thing to be careful of: outfits that advertise "$100-$500 automated searches" or invention-promotion firms bundling a cheap "search" with upsells. A search is only worth what the analysis attached to it is worth.
