Sterne Kessler, Thomson Reuters Launch AI Patent Tool

Sterne Kessler and Thomson Reuters launched the Patent Claim Eligibility Analyzer on May 13, 2026, a new AI tool built for Section 101 patent litigation analysis.

The tool addresses one of the most resource-intensive tasks in patent law. Section 101 governs patent eligibility in the United States, and its analysis is time-consuming because key legal concepts lack clear definitions, courts apply the same test differently across similar inventions, and the process is heavily dependent on case precedent.

The Problem It Solves

Patent litigators on both sides of a case need fast, reliable eligibility assessments. Patent owners must understand a patent's vulnerability before filing a lawsuit. Defendants need a quick path to an early case dismissal.

Until now, this analysis took days to complete. The new tool aims to deliver results in minutes.

Daniel Block, director in Sterne Kessler's Electronics Practice Group and leader of Sterne Kessler Labs, stated: "For patent owners seeking to assert a patent, understanding its vulnerability under Section 101 is essential before litigation begins. For defendants, a fast, reliable eligibility assessment can reveal a path to an early win. Both sides want information fast."
