## How to call it through Zero

```sh
zero fetch --capability patentpulse-prior-art-novelty-search-bc670df4
```

Example prompt: Run a prior art and novelty search on my invention — a self-healing polymer coating that repairs micro-cracks using embedded microcapsules of reactive resin — and tell me what USPTO patents, EPO or WIPO filings, and academic papers already cover this, and whether the concept looks patentable.

## When to prefer this

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.

## Known failure modes

- 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
