The answer, as recorded

Here's how I'd actually approach it, in the order I'd try them. ## Start free - these are genuinely good, not consolation prizes **1. Google Patents** - The one I'd open first. Full-text search across US, EP, WIPO, CN, JP and more, with machine translation and prior-art links built in. For a first-pass "has anyone already done this?" check, it's fast and requires no account. Weakness: search syntax is shallower than the specialist tools, and coverage of very recent filings can lag. → [patents.google.com](https://patents.google.com) **2. USPTO Patent Public Search** - Use this once Google turns something up. It's the authoritative source for US patents and published applications, and its advanced query syntax (field codes, classification searching) is what actually lets you do a defensible search. If you're filing in the US, your search isn't complete without it. → [uspto.gov/patents/search/patent-public-search](https://www.uspto.gov/patents/search/patent-public-search) **3. Espacenet (EPO)** - Best for non-US coverage and for *patent families*, which show you every jurisdiction a given invention was filed in. Instant translation across 30+ languages. If your market is international at all, run your search here too. → [worldwide.espacenet.com](https://worldwide.espacenet.com/) **4. WIPO PATENTSCOPE** - Rounds out the set for PCT/international applications. Honestly, for most small businesses the free tier is where the decision gets made. If these three turn up close prior art, you've saved yourself a few thousand dollars and you're done. ## Free human help - check eligibility before you pay anyone **5. USPTO Patent and Trademark Resource Centers (PTRCs)** - A network of public and university libraries with librarians trained by USPTO to walk you through a search. Free. Wildly underused. → [uspto.gov](https://www.uspto.gov/learning-and-resources/support-centers/patent-and-trademark-resource-centers-ptrc) **6. USPTO Patent Pro Bono Program** - If your business is under the income/revenue thresholds, this matches you with a volunteer patent attorney for free. Regional programs, apply through your state's. Also worth looking at the Law School Clinic Certification Program. → [uspto.gov/patents/basics/using-legal-services/pro-bono/patent-pro-bono-program](https://www.uspto.gov/patents/basics/using-legal-services/pro-bono/patent-pro-bono-program) ## Paid, when you're about to spend real money on filing **7. A flat-fee patentability search from a registered patent attorney or agent.** This is what I'd recommend over any software subscription. Expect roughly **$500-$1,500** for a US-only single-technology search, up to $2,000-$3,000 in a crowded field; search plus a written attorney opinion typically runs **$1,500-$3,000**. The written opinion is the part with actual value - it's a professional judgment you can rely on, not a list of hits. Get the quote in writing before you engage. ([cost ranges](https://www.michaelmeyerlaw.com/blog/how-much-does-a-patent-cost-complete-2026-fee-guide/)) **8. Specialist search platforms - PatSnap, Clarivate Derwent Innovation, Questel Orbit Intelligence, Patentcloud.** I'd name these last and with a caveat: they're excellent, but they're subscription tools built for people who search patents *regularly*. If you're clearing one or two inventions a year, a single flat-fee search from a professional costs less than a few months of subscription and gives you better output. Consider these only if patent landscaping is becoming a routine part of your work. ([overview](https://www.patsnap.com/resources/blog/articles/best-patent-search-platforms-2026/)) ## One warning Be careful with heavily-advertised "invention promotion" and "patent application service" companies that market to inventors and small businesses - this category has a long history of high-fee, low-value operations, and USPTO maintains a complaints database on them. If a service found *you* through an ad and pushes urgency, slow down. A registered patent attorney or agent (verifiable in the USPTO practitioner roster) is the safer spend. **My actual recommendation:** run Google Patents → USPTO Patent Public Search → Espacenet yourself over a weekend, take what you find to a PTRC librarian for free, and only then pay for a flat-fee professional search with a written opinion if you're still planning to file.
