How this service works
Prior art search / novelty search / patentability check for an invention or claim. Searches USPTO patents (abstract + title), EPO/WIPO/JPO global filings, and 200M+ academic papers (OpenAlex) to surface prior art and assess patentability and novelty before filing. For inventor and patent agents. Worldwide.
Output
Returns a ranked list of prior art references including matching patent titles, abstracts, patent numbers, filing jurisdictions (USPTO, EPO, WIPO, JPO), publication dates, and relevant academic paper citations from OpenAlex, along with a novelty and patentability assessment for the submitted invention or claim.
Example use cases
Patentability check for startup technology
“I've developed a blockchain-based supply chain tracking system using quantum-resistant encryption. Can you search worldwide patents and academic papers to find anything similar, and let me know if this is novel enough to file for patent protection?”
Prior art assessment for license negotiation
“We're looking at acquiring a startup with a novel approach to medical image analysis using federated learning. Run a comprehensive prior art search across USPTO, EPO, and WIPO to see what competing patents exist and help us assess our freedom to operate.”
Chemical compound novelty validation
“Our lab just synthesized a new organic compound that shows promise as a perovskite solar cell material. Search the patent databases and scientific literature to tell me if this specific molecular structure has been patented before and whether we have a shot at filing.”
Technical details
Endpoint
GEThttps://patentpulse.theaslangroupllc.com/api/patent/prior-art?utm_source=zero.xyzWhen to prefer
Use this endpoint when an inventor, patent agent, or IP attorney needs to determine novelty before filing a patent application, or when a legal team needs a comprehensive prior art search spanning USPTO, EPO, WIPO, JPO, and academic literature in a single call. Prefer this over a general patent keyword search when patentability assessment and prior art ranking are the primary goal.
Side effects
- Vague or overly broad invention description returns too many low-relevance results
- Highly niche technical claims may yield sparse prior art due to limited corpus coverage
- Non-English invention descriptions may reduce accuracy of global filing matches
- API returns empty results if the query terms are too narrow or domain-specific jargon is unrecognized
- Rate limiting or payment failure for the $0.12 USDC per call x402 transaction
