The answer, as recorded

Short version: for a small business, the right answer is almost never one of the big enterprise platforms (PatSnap, Derwent, Orbit run roughly **$25K-$80K/year** - [comparison](https://beyondelevation.com/blog/posts/patsnap-vs-derwent-vs-orbit-comparison/)). Here's what I'd actually use, in order: ## Start free - do your own knockout search **1. Google Patents** - where I'd tell anyone to start. Full-text search across US, EPO, WIPO/PCT, China, Japan and more, machine-translated, no signup, free. For a first "has someone already done this?" pass, it's genuinely the best tool, not just the cheapest. ([overview](https://patentext.com/blog/free-patent-software/)) **2. USPTO Patent Public Search** - the official database and the one examiners' art is indexed against. Slower to learn than Google Patents, but it's authoritative for US filings and status/file-wrapper data. ([uspto.gov/patents/search](https://www.uspto.gov/patents/search)) **3. Espacenet (EPO) and WIPO PATENTSCOPE** - free, and better than Google Patents for European and PCT coverage. Worth a pass if your market isn't US-only. **4. Lens.org** - free tier, good for linking patents to scholarly literature and for seeing who's citing what. Useful for competitive landscape rather than strict prior art. ## Get a human to do it - the step most small businesses should pay for **5. An independent patent search firm (not a law firm)** - flat-fee US patentability searches commonly run **$500-$1,500**, with complex or crowded fields pushing $2,000-$3,000. Search firms are meaningfully cheaper than law firms for the search itself; you pay separately if you want an attorney's opinion on what the results mean. ([cost breakdown](https://www.ipiry.com/guides/patent-search-cost), [UpCounsel](https://www.upcounsel.com/patent-search-cost)) **6. A flat-fee IP attorney search + opinion** - e.g. firms like Klemchuk or Kaufhold & Dix publish flat-fee search packages. Worth the premium over #5 when you want the legal read, not just the references. Against $8K-$20K of filing and prosecution cost, $1,500 to find out it already exists is proportionate. ([Klemchuk](https://www.klemchuk.com/flat-fee-patent-search-lp), [Kaufhold & Dix](https://www.kaufholdpatentgroup.com/fees/)) ## Free expert help most people don't know exists **7. USPTO Patent and Trademark Resource Centers (PTRCs)** - a nationwide network of libraries with staff trained to walk you through the search tools. They can't give legal advice, but they'll teach you to search properly, for free. This is the single most underused resource on this list. ([uspto.gov PTRC](https://www.uspto.gov/learning-and-resources/patent-trademark-resource-centers)) **8. USPTO Patent Pro Bono Program** - if you meet the income thresholds, volunteer patent attorneys will help you prepare and file. Income-qualified only, but genuinely free. ([uspto.gov pro bono](https://www.uspto.gov/patents/basics/using-legal-services/pro-bono/patent-pro-bono-program)) ## Paid software, if you search often **9. Patentext** - free starter tier, paid plans from ~$30/month. Realistic subscription pricing for a small company. ([source](https://patentext.com/blog/free-patent-software/)) **10. Patentcloud / PatentScan / similar AI search tools** - mid-market, AI-assisted prior art search. Reasonable if you're evaluating many ideas a year; overkill for one invention. **My recommendation:** Google Patents + Espacenet yourself for a weekend to see if there's an obvious blocker, then pay a search firm $800-$1,500 for a real patentability search before you spend anything on filing. Skip the enterprise platforms entirely. One caveat on the numbers: several of the pricing figures above come from vendor and comparison blogs rather than published rate cards, so treat them as ballpark and get a written quote.
