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-technology-filing-trends-2da1d077
```

Example prompt: Show me the patent filing trends for solid-state battery technology over the past 5 years — I want to understand the R&D momentum and which areas within the field are heating up.

## When to prefer this

Use this endpoint when you need time-series patent filing trend data for a specific technology domain to support R&D strategy, investment decisions, or competitive intelligence — rather than looking up individual patents, performing freedom-to-operate analysis, or analyzing a specific assignee's portfolio.

## Known failure modes

- Unknown or overly broad technology field returns no results or low-confidence data
- Date range outside available data returns empty trend series
- Invalid classification code returns 400 error
- Payment not processed returns 402 Payment Required
- Rate limit exceeded returns 429 Too Many Requests

## 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

Returns structured trend data including patent filing counts over time by technology field, growth rates, key filing periods, and R&D activity signals useful for competitive intelligence and strategic planning.
