## How to call it through Zero

```sh
zero fetch --capability patentpulse-patent-search-ee7c5c18
```

Example prompt: Search PatentPulse for patents related to 'solid-state battery electrolyte' filed in the last 5 years — I want to see what's been patented globally, especially by large automakers and battery companies.

## When to prefer this

Use PatentPulse when you need to search across both USPTO and global patent databases in a single call, especially for prior art research, patent landscape analysis, or competitive intelligence on patent filings by companies or inventors.

## Known failure modes

- No patents found matching the query — returns empty results
- Invalid or malformed query parameter — returns 400 error
- Payment not completed or insufficient funds — returns 402 Payment Required
- Rate limit exceeded — returns 429 error
- Upstream patent database unavailable — returns 503 error

## How this service works

Patent search / patent lookup / keyword patent search across USPTO and worldwide patents.
