## Run it

From code, with a Fous API key in `FOUS_API_KEY`; the answer's `data` holds the output:

```bash
curl https://api.fous.com/v1/runs \

  -d '{"method":"patents.google.com/list_company_patents","input":{"topic":"battery","company":"Siemens","max_recent":5,"filed_after":"2024-01-01","filed_before":"2024-01-31"}}'
```

From an AI agent connected to the Fous MCP server: its `run` with the same method and input. To connect one, give it `set up https://fous.com/SKILL.md`.

## Ask your agent

- Give me an overview of Tesla's patent filings on battery cooling since 2019: how many there are, the yearly trend, the main technology areas, and the most prolific inventors.
- Use Google Patents to break down Siemens' patent portfolio from 2015-01-01 to 2023-12-31. I want filings per year and the 10 most recent patents with their grant status.
- Who are the top inventors at Medtronic working on insulin pumps, and what has the company filed recently? Limit it to the last 5 recent filings.
- I'm doing competitive research on Samsung's foldable display IP filed between March 2018 and June 2024. Can you check Google for the total count, the dominant CPC areas, and links to the 30 latest patents?
- How active has Moderna been in patenting mRNA lipid nanoparticle tech over the past decade? Show the year-by-year filing counts and the latest patents with filing and grant dates.
