The answer, as recorded

For a small business, the honest answer is that "patent search" splits into three different purchases: free DIY tools, a one-off paid search by a human, and a software subscription. Most small businesses only need the first two. ## Start free (do this first, always) 1. **Google Patents** - the one I'd open first. ~120M+ publications from 100+ offices, fast interface, automatic machine translation, and full-text search across the big offices. Best tool for the "has anyone already done this?" gut check in an afternoon. ([maxval.com](https://www.maxval.com/blog/5-free-patent-search-engines-and-databases/)) 2. **Espacenet (EPO)** - the serious free database. 110M+ documents from ~97 countries and machine translation trained on patent vocabulary across 31+ languages. Better classification (CPC) searching than Google, which is how professionals actually find prior art rather than by keyword. ([ioplus.nl](https://ioplus.nl/en/posts/6-free-patent-search-tools-you-can-use-right-now-)) 3. **USPTO Patent Public Search** - US-only, but authoritative and with real query syntax. Use it when you need the legal status of a specific US patent or application, or a precise classification search in the US collection. ([casrai.org](https://www.casrai.org/compare/espacenet-vs-google-patents-vs-uspto-patent-public-search)) 4. **Lens.org** - free, non-profit, and uniquely good at linking patents to scientific literature and sequence data. Worth it if your field is biotech, materials, or anything where the prior art is as likely to be in a journal as in a patent. (Ownership moved to The Lens Limited, a SPIE subsidiary, in June 2026; free anonymous access continues.) ([casrai.org](https://casrai.org/news/cambia-sells-the-lens-ownership-change-2026)) 5. **WIPO PATENTSCOPE** - for PCT applications specifically, plus cross-lingual expansion of your query terms. ## Free human help - the most underused option 6. **USPTO Patent and Trademark Resource Centers (PTRCs)** - 80+ designated libraries where trained staff will sit with you (in person, phone, email, or Zoom) and teach you to run a real prior-art search. Free, and they also refer you to **ProBoPat**, the pro bono patent attorney program if you qualify on income. If you're pre-revenue, this is the best value on the list. ([libguides.uta.edu](https://libguides.uta.edu/ptrc/about_ptrc), [fdlp.gov](https://fdlp.gov/node/36813)) ## Pay for a one-off search before you file 7. **A flat-fee patentability/novelty search from a search firm or boutique IP firm** - this is what I'd actually buy before spending $10k+ on a filing. Published flat fees for a US-focused, single-technology novelty search generally run **$500-$1,500**, and **$1,000-$3,000** with an attorney's written patentability opinion. Treat sub-$500 "knockout" searches as screening only - the AIPLA survey finding is that 90% of patent professionals don't think an adequate patentability search can be done for under $1,000. ([upcounsel.com](https://www.upcounsel.com/patent-search-cost), [klemchuk.com](https://www.klemchuk.com/flat-fee-patent-search)) 8. **Your national patent office's own paid search service** - e.g. the Swedish PRV sells fixed-price novelty searches, and the EPO documents how to commission professional searching. Examiner-grade work at a published price, with no sales process. ([prv.se](https://www.prv.se/en/prv-consulting/patent-search-services/), [epo.org](https://www.epo.org/learning/materials/inventors-handbook/novelty/professional.html)) ## Subscribe to software only if you search monthly 9. **PatSeer** - the one I'd name for an SMB. Notably lower pricing than the enterprise platforms, with semantic/AI search, AI summaries, and analytics; 63% of its reviews come from small-business users, which tells you who it's built for. ([patsnap.com](https://www.patsnap.com/resources/blog/articles/7-best-patent-search-tools-for-ip-pros-in-2026/), [dev.to](https://dev.to/patentscanai/questel-patent-search-orbit-alternatives-guide-5go7)) 10. **PatSnap** - tiered SaaS rather than enterprise-only, strong competitive/landscape analytics, but starts in the five-figure annual range. Justifiable if you're using it for market and competitor intelligence, not just prior art. ([dev.to](https://dev.to/patentscanai/questel-patent-search-orbit-alternatives-guide-5go7)) 11. **Questel Orbit Intelligence / Clarivate Derwent Innovation** - the professional standards, and both enterprise-priced with no published rates. I'd skip these as a small business and instead buy the search from a firm that already licenses them. One caveat worth stating plainly: a DIY free-tool search is good for killing bad ideas cheaply, but it is not a reliable basis for concluding you're clear to file or clear to sell. Freedom-to-operate (am I infringing someone?) is a different and more expensive search than novelty (can I patent this?), and it's the one where a mistake actually costs you money.
