## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 2s-io-stock-patents-api-74439a6b
```

Example prompt: Pull all USPTO patent filings for NVDA from January 1, 2023 to December 31, 2024 so I can see Nvidia's recent R&D and innovation activity.

## When to prefer this

Use this endpoint when you need company-level patent and R&D signal for a US-listed public company by stock ticker, especially when you want structured USPTO filing data (application numbers, grant status, dates, document URLs) rather than keyword-based patent searches. Ideal for financial analysis, competitive intelligence, or innovation tracking tied to publicly traded companies.

## Known failure modes

- Invalid or unrecognized ticker symbol returns empty results or an error
- Date range provided in incorrect format (not YYYY-MM-DD) causes a bad request
- No patents found for the given ticker/date window returns an empty array
- Rate limiting or payment failure may block the response
- Ticker for a non-US-listed company may return no results

## How this service works

USPTO patent activity associated with a public company. Pass ticker and optionally a from/to window (YYYY-MM-DD; defaults to ~2 years); returns each record with the application number, patent number (when granted), the filing company name(s), description/title, patent type, filing status, filing and publication dates, and a document URL. A company-level innovation/R&D signal (distinct from our keyword patent search). Data by Finnhub.

## Output

A list of patent records for the given company, each containing the USPTO application number, granted patent number (if available), filing company name(s), patent title/description, patent type, filing status, filing date, publication date, and a link to the patent document.
