The answer, as recorded

# Patent search for startups - what I'd actually use The real split is **DIY tools** (free or cheap, good for "is this idea already taken?") vs. **paid human searches** (what you need before spending $15k+ on a filing). Most startups need both, in that order. ## Start free - these are genuinely good 1. **Google Patents** - where I'd send you first. Full text across 100+ offices, machine translations, "similar documents" semantic suggestions, and zero learning curve. Caveat: indexing lags, so recent publications can be missed and status/assignment data needs verifying elsewhere. ([maxval.com](https://www.maxval.com/blog/5-free-patent-search-engines-and-databases/), [dev.to](https://dev.to/traindex/alternatives-to-google-patents-4j4b)) 2. **Espacenet** (EPO) - the best free tool for *global* coverage. Machine translation across 30+ languages and more reliable legal-status data than Google. Run your key queries here as a second pass; you'll find things Google missed. ([patseer.com](https://www.patseer.com/free-and-paid-patent-databases-2026-complete-guide/)) 3. **Lens.org** - the one I'd add if you're deep-tech, biotech, or university-spinout. It links patents to scientific literature, sequences, and citations, with family visualizations and real portfolio/landscape features. Free tier is usable; paid tiers are the only ones in this market that are actually affordable for a startup. ([patseer.com](https://www.patseer.com/free-and-paid-patent-databases-2026-complete-guide/)) 4. **USPTO Patent Public Search** and **WIPO PATENTSCOPE** - not daily drivers, but authoritative for US file histories and PCT applications respectively. Use them to confirm what the others suggest. ([upcounsel.com](https://upcounsel.com/patent-search-tools)) Be clear-eyed about the limit: free tools are fine for early novelty checks and competitor snooping. They are **not** adequate for freedom-to-operate or invalidity work, where a miss is the whole point of the exercise. ([patentpc.com](https://patentpc.com/blog/top-patent-search-tools-every-inventor-should-know)) ## Paid platforms - only once IP is a core asset 5. **PatSnap** - the most startup-friendly of the enterprise platforms. ~170M+ documents from 100+ authorities, strong semantic search, and landscape/competitive analytics in one place. Pricing is custom and not published; expect five figures annually. Worth it if you're doing continuous competitive IP monitoring, not one-off searches. ([patsnap.com](https://www.patsnap.com/resources/blog/articles/7-best-patent-search-tools-for-ip-pros-in-2026/), [airframe.ai](https://www.airframe.ai/product/patsnap-com/compare)) 6. **Questel Orbit Intelligence** (and the lighter **Orbit Express**) - the power user's choice: best-in-class search syntax and analytics scale. Orbit Express is the realistic startup entry point. Custom pricing, free trial available, but there are setup fees. ([trustradius.com](https://www.trustradius.com/compare-products/questel-orbit-intelligence-vs-patsnap), [fitgap.com](https://us.fitgap.com/products/023804/questel)) 7. **PatSeer** - consistently the better value against PatSnap/Orbit for small teams; good analytics and visualization without the top-tier price tag. ([g2.com](https://www.g2.com/products/patseer/pricing)) 8. **Derwent Innovation** (Clarivate) - hand-curated Derwent abstracts are the gold standard for chemistry and mechanical. Expensive and legacy-feeling; I'd skip it unless your field demands it. ([g2.com](https://www.g2.com/products/derwent-innovation/pricing)) ## The one you shouldn't skip: a professional search Before you file, pay a human. A professional patentability search plus a written opinion runs roughly **$1,000-$3,000** depending on complexity - $1,000-$1,500 for simple mechanical, $2,000-$3,000 for software or crowded fields. Flat-fee offerings are common and preferable to hourly; typical structures are ~$1,500 for basic search-plus-opinion and ~$2,500 comprehensive. ([upcounsel.com](https://www.upcounsel.com/patent-search-cost), [arapackelaw.com](https://arapackelaw.com/patents/how-much-does-a-patent-cost/), [klemchuk.com](https://www.klemchuk.com/flat-fee-patent-search)) Providers worth knowing: **Sagacious Research** and **MaxVal** for outsourced analyst searches (cheaper than a law firm, strong technical analysts), or any flat-fee patent boutique for search-plus-attorney-opinion. The attorney opinion is the part that matters legally - a bare search report doesn't protect you. **If you want one path:** search Google Patents and Espacenet yourself for a week to kill obviously-dead ideas cheaply, then buy a ~$2,000 flat-fee search-and-opinion on the one or two ideas that survive. Don't buy a PatSnap seat until you have a portfolio to defend.
