Patent Bear Expands Research With Forward Art, Search by Meaning, and European Case Law

CALIFORNIA, October 27, 2026: Patent Bear today released a set of new research tools on the web and in its Claude and ChatGPT connectors.

• Forward Art finds the art that came after a patent, from its priority date to its estimated expiry, and charts it against the claims.
• Search by meaning finds patents that claim the same thing in different words, grouped by family and owner, across tens of millions of claims.
• Proceedings research covers district court, Federal Circuit, PTAB, and USPTO proceedings in one place, searchable by patent, judge, court, and issue.
• European coverage adds EPO Boards of Appeal decisions and the European Patent Register, alongside EP patents and applications.
• Worldwide families and status show a patent's family members across offices and where each one stands.

Every result links back to the source document, with a citation on every passage.

Availability

The new tools are available today at patentbear.com and through the Patent Bear connector in Claude and ChatGPT.
