How this service works
A company's US patents from the USPTO Open Data Portal, newest filings first. Pass `?company=Tesla` (required, matches APPLICANT name — subsidiaries/variants need separate queries) plus `?limit=` (max 100). Each carries patent & application numbers, title, filing & grant dates, status, applicant, inventors, and a link. From x402stock, a market & economic data API (x402, USDC).
Output
A JSON object containing the company name, data source (USPTO), as-of timestamp, total number of matched patents, a count of returned records (up to the requested limit), and an array of patent objects each with patent number, application number, title, filing date, grant date, status, applicant name, inventors list, and a Google Patents URL. Also includes an attribution string crediting the USPTO Open Data Portal.
Example use cases
Example prompt
“Pull the top 20 USPTO patents for Tesla from x402stock — I want the patent numbers, titles, inventors, filing dates, and grant dates.”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/patents?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured patent data directly from the USPTO for a named company, including patent numbers, inventors, and filing/grant dates. Prefer this over web scraping or general search when you need machine-readable patent records with provenance attribution, and when you're already operating in an x402 pay-per-call context without API key management overhead.
Side effects
- Company name not found or too short (minLength 2) — returns empty results or validation error
- Limit exceeds 100 or is 0 or negative — schema validation error
- USPTO data source temporarily unavailable — upstream API error
- Payment failure via x402/USDC — 402 Payment Required response
- Company name matches multiple entities ambiguously — may return mixed results
