The answer, as recorded

## Free - start here, this covers most startup needs **Google Patents** - fastest path to a usable answer. Full-text across 100+ offices, machine translations, and the "Similar Documents" panel does a decent semantic job. Known weaknesses: a lag on very recent publications, and you should verify legal status elsewhere. For a founder doing a first sanity check before spending money, this is the right first stop. **Espacenet (EPO)** - the one I'd use as the serious free follow-up. Its Citation View shows cited patent families in one place and *separates inventor citations from examiner citations*, which is genuinely rare and tells you what an examiner thought was close. Also the best CPC classification browsing, which is how you actually find prior art you weren't searching for. **Lens.org** (Cambia, non-profit) - free, and the one that combines patents + scholarly literature + biological sequences + citation analytics. Best choice if your prior art is likely academic papers rather than patents (common in biotech, ML, materials) or if you want basic portfolio/landscape visualizations without paying. **WIPO PATENTSCOPE** - worth a pass for its cross-lingual expansion (search in English, hit Chinese/Japanese/Korean filings) and for PCT applications at their earliest publication. ## Paid tools, if you're searching repeatedly **IPRally** - my default paid recommendation for a startup. Graph-based AI search built by patent professionals, and it's materially better than keyword search at finding conceptually similar art. Reasonable for small teams rather than enterprise-only. **PatSeer** - the one explicitly priced for startups and SMEs with tiered SaaS plans, versus the enterprise incumbents. Good analytics-per-dollar if you need landscaping, not just search. **PatSnap** - broadest global coverage (US/EP/JP/KR/CN) plus analytics and competitive intelligence. Capable, but priced in tiers with modular add-ons that get expensive, and it's more than most seed-stage companies need. Consider it if IP is a core part of your fundraising story. **Questel Orbit Intelligence** and **Clarivate Derwent Innovation** - the professional standards (Derwent's human-written abstracts are legitimately valuable; Orbit's search syntax is the most powerful). I'd skip both as a startup: enterprise-only, quote-based pricing, no public pricing. You'll touch them indirectly through your attorney. ## The thing I'd actually spend money on **A flat-fee novelty/patentability search from a patent firm or a dedicated search shop** - before you file, and before an FTO decision. Published flat fees generally run **~$500-$1,500** for a US-only single-technology search, and **~$2,000-$3,000** for a crowded or technically complex field; firms billing hourly are commonly $150-$400/hr. Examples of published flat-fee offerings sit around $1,500-$2,500 per invention with roughly a one-week turnaround. Search specialists like **MaxVal** and **Sagacious Research** serve this market directly if you'd rather not go through a law firm's markup. **My honest recommendation:** do your own sweep in Google Patents + Espacenet first to kill obviously-dead ideas cheaply, then pay for one professional flat-fee search on the invention you're actually filing. Free tools are fine for discovery but are not adequate when you need a systematic, defensible prior-art review - and a $1,500 search that prevents a $15k-$20k doomed application is the best-value spend in startup IP.
