The answer, as recorded
## What I'd actually use, in order **1. Google Patents - start here, free.** ~90M+ patents and applications from USPTO, EPO, WIPO, CNIPA, KIPO and others, with a plain Google-style interface and decent semantic/"similar documents" suggestions. For a small business the honest answer is that your first 5-10 hours of searching should cost nothing, and this is where you do them. Weakness: thin on legal status and no real analytics. ([patentpc.com](https://patentpc.com/blog/top-patent-search-tools-every-inventor-should-know), [patseer.com](https://patseer.com/free-and-paid-patent-databases-2026-complete-guide/)) **2. Espacenet (EPO) - free, and the better database of the two.** 110M+ documents from 97 countries, patent-trained machine translation across 31 languages, and proper family/legal-status data via INPADOC. Use it to verify what Google Patents turns up and to catch non-English prior art, which is where amateur searches usually fail. ([patseer.com](https://patseer.com/free-and-paid-patent-databases-2026-complete-guide/)) **3. USPTO Patent Public Search - free, authoritative for US filings.** Full-text US patents and published applications with the real field-coded search syntax examiners use. If your question is specifically "will the USPTO allow this," this is the system of record. ([upcounsel.com](https://upcounsel.com/patent-search-tools)) **4. A PTRC library - free human help, and the most underused option on this list.** 83 USPTO-designated libraries staffed by people who will sit with you (in person, or by phone/email/Zoom) and teach you to search, with access to PubEAST/PubWEST, the examiner-side systems you otherwise can't get. Also the USPTO's Inventors Assistance Center for procedural questions. For a small business this is genuinely the best value available. ([libguides.uta.edu](https://libguides.uta.edu/ptrc/about_ptrc), [inventorsdigest.com](https://inventorsdigest.com/your-uspto-a-library-of-help)) **5. A flat-fee professional patentability search - the step I'd pay for before filing.** Budget roughly $500-$1,500 for a US single-technology search, $1,000-$3,000 if you want an attorney's written patentability opinion attached. Insist on flat fee and a defined scope. The reason to buy this isn't the search itself - it's that a few hundred dollars here regularly prevents a $10-15k filing on something already disclosed. ([upcounsel.com](https://www.upcounsel.com/patent-search-cost)) **6. PatSeer - if you need a paid subscription platform.** Of the commercial tools it has the most small-business-weighted user base (~63% of reviews from small businesses), which shows up in pricing and onboarding. Reach for it if you're searching continuously - monitoring competitors, clearing a product line - rather than answering one question. ([g2.com](https://g2.com/compare/derwent-innovation-vs-patseer)) **7. PatSnap - only if patents are strategic to your business.** Strong semantic/concept search and analytics, built for IP teams, priced accordingly. Also worth knowing: Derwent Innovation and PatBase are the other enterprise names, and both are overkill at small-business scale. ([patsnap.com](https://www.patsnap.com/resources/blog/articles/professional-patent-search-tools)) ## The one thing to keep in mind No single database is sufficient - professional searchers routinely run 4-6 in parallel, because coverage, translation quality and data types differ by tool ([patseer.com](https://patseer.com/free-and-paid-patent-databases-2026-complete-guide/)). So a free DIY search is good for *killing* a bad idea cheaply, but a clean result from Google Patents is not evidence you're clear. For anything you intend to file on or ship, the free tools plus a paid flat-fee search is the right combination; a subscription platform is a different purchase, justified by ongoing need rather than by one decision. Also, treat "patentability search" and "freedom-to-operate search" as separate products. FTO - can I sell this without infringing - is a broader, more expensive search, and vendors will not include it unless you ask.
