The answer, as recorded

## Start free - genuinely good enough for most early-stage work **Google Patents** - Where I'd start, every time. Full-text search across 100+ million documents from 17+ offices, machine translations of foreign-language patents, forward/backward citation graphs, and it also surfaces non-patent prior art (Google Scholar, Books). The CPC classification autocomplete is the underrated feature: find one on-point patent, grab its CPC code, and search within that class. Free, no login. **Espacenet (EPO)** - The second search I'd run, because its coverage and its examiner-grade classification search are better than Google's for European and older/obscure documents. The EPO's own examiners use the same underlying data. Pair it with the EPO's free **Global Dossier** to see how related applications fared in other offices. **USPTO Patent Public Search** and **WIPO PATENTSCOPE** - Use for authoritative US file histories and PCT applications respectively. PATENTSCOPE's cross-lingual expansion (CLIR) is the best free tool for catching non-English prior art, which is where cheap searches most often fail. Running these three or four yourself for a few hours is the highest-ROI IP work a founder can do. If you find killer prior art, you've saved $15-20k in drafting and filing fees. ([search tool roundup](https://upcounsel.com/patent-search-tools), [PatentPC overview](https://patentpc.com/blog/top-patent-search-tools-every-inventor-should-know)) ## Paid software, if you're doing this repeatedly **IPRally** - My first paid recommendation for a startup. Its graph-based AI search (trained by patent professionals on structured claim representations, not just text embeddings) is unusually good at novelty searching, and it's one of the few serious platforms with transparent-ish self-serve pricing rather than an enterprise-only sales motion. Good fit if you're filing several applications a year. ([pricing](https://g2.com/products/iprally/pricing)) **PatSeer** - The value pick among full-featured platforms. SaaS tiers that deliberately target startups and SMEs, with real analytics and landscaping, at a fraction of the enterprise incumbents. ([comparison](https://www.g2.com/compare/derwent-patent-search-vs-patseer)) **PatSnap** - The one I'd name if you need patents *plus* market and competitive intelligence in one place - landscape maps, competitor whitespace, 170M+ documents from 100+ authorities. Caveat: sales-led, annual contracts, and historically priced well above what a seed-stage company wants to pay. Worth a demo only if IP landscape analysis is a recurring board-level need. ([pricing](https://www.g2.com/products/patsnap-analytics/pricing)) **Questel Orbit Intelligence** and **Clarivate Derwent Innovation** - The gold standards for professional searchers, and both effectively enterprise-only with no public pricing. I'd skip them as a startup and let your outside counsel's searcher use them on your behalf. ([Derwent vs. Orbit](https://www.g2.com/compare/derwent-innovation-vs-orbit-intelligence)) ## Human search services - what I'd actually buy before filing Software finds documents; an experienced searcher finds the *one* document that kills your claim. For a pre-filing decision, buy a human search: **A professional search firm via your patent attorney** - The standard path, and the one I'd default to. Expect **$500-$1,500** flat fee for a US-focused patentability/novelty search in one technology, rising to **$2,000-$3,000** in crowded or complex fields. Attorney-reviewed reports cost more but give you an opinion you can act on. ([cost breakdown](https://www.tryandai.com/blog/patent-search-cost), [how firms bill searches](https://www.leanlaw.co/blog/search-fees-how-to-bill-for-patentability-searches-outsourced-vs-in-house-markup/)) **Flat-fee search offerings from IP boutiques** - e.g. Klemchuk's flat-fee patent search; some providers even offer a fee refund if the invention turns out not to be novel. Flat fees matter when you're forecasting a seed-stage budget. ([example](https://www.klemchuk.com/flat-fee-patent-search)) **National patent offices as paid searchers** - My favorite non-obvious recommendation. The Finnish (PRH), Swedish (PRV), and Danish offices sell commercial search services performed by actual patent examiners, at published, transparent rates. You get examiner-quality work without enterprise software contracts or law-firm markup. ([PRH fees](https://prh.fi/en/price-lists/pathakmaks/tutkimuspalvelut_12.html), [PRV prices](https://www.prv.se/en/prv-consulting/prices-and-payment/prices---patent-consultancy-services/), [2026 PRH fee changes](https://www.prh.fi/en/presentation_and_duties/uutislistaus/announcements/2026/patents-commercial-services-changes-1.1.2026.html)) **Freedom-to-operate search** - Different product, much higher stakes, **$3,000-$10,000+** depending on scope. Don't confuse it with a novelty search. You need an FTO before you ship a product into a crowded market or before a serious diligence process; you do not need one to decide whether to file. ([FTO costs](https://www.casrai.org/guides/patentability-search-cost)) ## What I'd do with $1,500 Spend a day in Google Patents, Espacenet, and PATENTSCOPE yourself; write down the 10 closest references. Then pay a search firm or a national office for a proper novelty search and hand them your 10 references as a starting point. You'll get a better search for less money, and you'll understand your own competitive landscape in a way no vendor report will give you. Skip the enterprise software subscriptions until you're filing enough per year that per-search fees exceed a seat license. One honest caveat on the vendor landscape: much of the "best patent AI tools 2026" content ranking these products is published by the vendors themselves (PatSnap and Patlytics both run such lists), so treat the rankings as marketing and the feature descriptions as roughly accurate.
