Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 patentpulse-patent-trends-7299fee5
```

Example prompt: Can you pull the global patent filing trends for solid-state battery technology — something like CPC code H01M — so I can see how innovation activity is moving across USPTO, EPO, and other major patent offices?

## When to prefer this

Use this endpoint when you need time-series or trend analysis of patent filing activity rather than individual patent lookup or search. Ideal for competitive intelligence, R&D strategy, investment due diligence, or technology benchmarking where the question is 'how is this technology area growing?' rather than 'find me this specific patent.'

## Known failure modes

- Invalid or unrecognized CPC code returns empty or error response
- Overly broad technology area string yields low-confidence or generic results
- Unsupported language parameter may fall back to English or return an error
- Empty response object if no trend data exists for the queried area
- Rate limiting or payment failure returns 402 with x402 payment required header

## How this service works

Patent trends / technology filing-trend analysis for a tech field or CPC class. Returns USPTO filing-volume trend by year, top filers/assignees, notable recent patents, global filing context (China/EU/Japan), and the academic research frontier (OpenAlex). For R&D-strategy and competitive-intelligence agents. Worldwide.

## Output

A JSON object containing patent filing trend data for the specified CPC classification or technology area, aggregated across major patent offices including USPTO, EPO, WIPO, JPO, and CNIPA. May include trend lines, filing volumes over time, and technology area breakdowns.
