Short answer

How can I check if a patent is still valid using AI?

Your agent uses the EPO Open Patent Services tool to pull real-time administrative data for specific patent filings. This lets you confirm if a patent is active, lapsed, or expired. You'll get a clear breakdown of the current legal standing for any patent number you provide.

The outcomes.

Where the data lands.

The AI processes the raw EPO data into these specific results.

VALIDITY

Current legal standing

The agent identifies if a patent is active, lapsed, or expired. You get the exact administrative status for the filing.

TIMELINE

Key administrative dates

Your AI extracts critical dates like expiration or renewal deadlines. This helps you track when a patent loses its protection.

DATA

Direct EPO records

The agent pulls official data straight from the EPO Open Patent Services. You receive the raw facts without any interpretation errors.

HUMAN

Legal review required

The AI provides the data, but you must verify the findings. It cannot provide legal advice or interpret how status affects your specific business strategy.

The workflow

What your AI does when the patent number arrives.

The agent handles the data retrieval so you don't have to navigate the EPO database manually.

  1. Identify the filing

    Your agent parses the patent number or identifier you provide in the chat to prepare the query.

    get_patent_legal_status

  2. Fetch status data

    The agent calls the EPO service to pull the most recent administrative records for that specific filing.

    get_patent_legal_status

  3. Verify validity

    The AI checks the retrieved data against known legal states like active or expired.

    get_patent_legal_status

  4. Summarize findings

    The agent presents the current legal standing and relevant dates in a clean, readable format.

    get_patent_legal_status
