The answer, as recorded
## What I'd actually use, in order **1. Google Patents** - Start here, always. Free, full-text search across ~87M+ patents from 17 offices, and crucially it searches non-patent literature (papers, product manuals) alongside patents, which is where a lot of startup-killing prior art actually lives. The semantic/AI search is now good enough that you can paste in a paragraph describing your invention and get useful hits. 90% of founders' early "am I novel?" questions get answered here. - [Google Patents](https://patents.google.com/), [comparison](https://casrai.org/compare/espacenet-vs-google-patents-vs-uspto-patent-public-search) **2. Espacenet (EPO)** - Free, and the best international coverage plus the strongest CPC classification search. Use it as the second database, because experienced searchers never rely on one. If you're going to file in Europe, this is the authoritative view. - [worldwide.espacenet.com](https://worldwide.espacenet.com/) **3. USPTO Patent Public Search** - Free and authoritative for US patents and applications specifically. Use it when you need a precise, reproducible, citable US-only result - e.g., checking the exact claim language or legal status of a specific patent you found elsewhere. - [USPTO](https://ppubs.uspto.gov/pubwebapp/), [overview](https://lib.guides.umd.edu/patent_tm/patent_search_tips) **4. Lens.org (The Lens)** - Free/low-cost nonprofit. ~155M+ patent records linked to ~270M scholarly works and biological sequences. This is the one I'd name for biotech/life-sciences startups and for anyone who wants citation-graph analysis and exportable data without an enterprise contract. - [lens.org](https://www.lens.org/), [review](https://patentailab.com/best-free-patent-search-engines-startups/) **5. A flat-fee professional search from a dedicated search firm** (Sagacious IP, Synoptic IP, or a boutique your patent attorney recommends) - Before you spend real money on filing, pay a human. Expect roughly **$500-$1,500** for a novelty/patentability search: ~$700-900 for software/electronics, ~$700-1,400 for chem/bio, with the overall market range running $150-$2,500 by complexity. That is the single highest-ROI IP spend a seed-stage company makes - it's cheap relative to a wasted $15-20K filing. Note these firms deliver references plus a relevance summary, *not* a legal opinion on your claims; get that from your attorney. - [Sagacious IP](https://sagaciousresearch.com/prior-art-search), [Synoptic IP](https://synopticip.com/pis/novelty-search-patentability-search/), [cost breakdown](https://casrai.org/guides/patentability-search-cost) **6. IPRally** - The paid tool I'd actually consider at Series A+, especially for deep-tech. It uses a graph neural network trained on patent examiner citations across ~125M publications, so it reasons about technical structure rather than keyword overlap. Mid-market pricing, and it now has an API/MCP connector if you want to wire it into your own workflows. - [iprally.com](https://www.iprally.com/) **7. Questel Orbit (Intelligence, or Orbit Express for smaller teams)** - Where I'd go if you need genuine freedom-to-operate work: claim-level mapping and legal-status tracking are the sharpest in the category, and coverage of EPO/WIPO beats the competition. Enterprise pricing (~$25-50K/yr for Intelligence), but **Orbit Express** is the cut-down tier built for exactly the "we're not a 20-person IP department" case. - [Orbit Intelligence](https://www.questel.com/patent/ip-intelligence-software/orbit-intelligence/), [Orbit Express](https://www.questel.com/patent/ip-intelligence-software/orbit-express/) **8. PatSnap** - Only if you're raising on an IP story or doing competitive landscaping for the board. Best-in-class visualizations, AI landscape dashboards, portfolio-vs-portfolio overlays. But it's ~$30-60K/yr and it's a *market intelligence* product more than a prior-art product. Most startups do not need this. - [Questel/PatSnap pricing comparison](https://beyondelevation.com/blog/posts/patsnap-vs-derwent-vs-orbit-comparison/) ## The honest shape of it For the large majority of startups: **Google Patents + Espacenet for free DIY searching, then one flat-fee professional search before you file.** That's it. Total cost under $1,500. Skip the enterprise platforms until someone is paying you to care about a portfolio. Two caveats on my sources: the $25-80K/yr platform pricing figures come from vendor and consultancy blogs rather than public price lists, so treat them as ballpark - all three enterprise vendors quote custom. And a fair number of "best patent tools 2026" listicles are SEO content promoting obscure products; I've deliberately only named tools with an established track record rather than repeating those rankings.
