Don't buy an enterprise subscription - those are five-figure annual contracts aimed at corporate IP departments. > > ## Start free (do this yourself, first week) > > 1. **Google Patents** - where I'd start, every time. 120M+ publications from 100+ offices, fast interface, good machine translation, and it's the only one that also pulls non-patent literature via Google Scholar and Books (important, because a journal paper or old product manual can kill your patent just as dead as a patent can).

Backed by AT&T and the Georgia IP Alliance, covers USPTO/EPO/WIPO plus ~11.5M scholarly articles. This is the single most useful tool for a non-specialist, because the usual failure mode of DIY searching is not knowing the vocabulary patent attorneys use for your own invention. > 3. **Espacenet** (Euro ## Brands named, in the order the engine gave | Position | Brand | How it was named | |---|---|---| | 1 | Google | mentioned | | 2 | Google Patents | mentioned | | 3 | PQAI | mentioned | | 4 | WIPO PatentScope | mentioned | | 5 | Espacenet | mentioned | | 6 | Lens.org | mentioned | | 7 | ProBoPat | mentioned | | 8 | flat-fee | mentioned | | 9 | Klemchuk | mentioned | | 10 | PatSnap | mentioned | | 11 | Questel | mentioned | | 12 | Questel Orbit | mentioned | | 13 | Orbit | mentioned | | 14 | Derwent | mentioned | | 15 | Derwent Innovation | mentioned | | 16 | PatSeer | mentioned | | 17 | MaxVal | mentioned | | 18 | UpCounsel | mentioned | ## Sources the engine cited - https://www.casrai.org/compare/espacenet-vs-google-patents-vs-uspto-patent-public-search (other) - https://www.maxval.com/blog/5-free-patent-search-engines-and-databases/ (vendor) - https://hackernoon.com/8-reasons-why-inventors-should-try-this-free-and-open-source-patent-search-engine (other) - https://www.g2.com/products/pqai/reviews (review) - https://arapackelaw.com/patents/artificial-intelligence-patent-search/ (other) - https://libguides.uta.edu/ptrc/about_ptrc (reference) - https://www.krwg.org/regional/2018-06-14/original-idea-patent-and-trademark-resource-center-at-nmsu-assists-innovators (other) - https://www.upcounsel.com/patent-search-cost (vendor) - https://www.casrai.org/guides/patentability-search-cost (other) - https://www.klemchuk.com/flat-fee-patent-search (vendor) - https://www.foxnews.com/us/low-cost-patent-search-options-for-inventors-on-a-budget (other) - https://www.g2.com/products/patseer/pricing (review) - https://dev.to/patentscanai/questel-patent-search-orbit-alternatives-guide-5go7 (other) - https://www.epo.org/learning/materials/inventors-handbook/novelty/professional.html (other) Permanent address of this answer: https://bikoosh.com/answers/s/patent-search-services-small-businesses-2026-10-23 ## Sources cited across the 20 recorded answers to this question Alphabetical;

Bikoosh is monitoring assistance, not complete protection. Answer Watch records what one AI answer engine said on one date, nothing more. Each page names the engine and the model, carries the date the question was asked, and lists the brands that appeared in the answer in the order the engine gave them, with the sources it cited. It is a measurement, not a ranking, not a recommendation and not a claim about the world. Brands that did not appear in an answer are not named on any public page.
