Thomson Reuters, Sterne Kessler partner for patent litigation AI tool

Sterne, Kessler, Goldstein & Fox and Thomson Reuters (TRI) announced a co-development partnership that has produced the first attorney-built AI workflow within CoCounsel Legal. The Patent Claim Eligibility Analyzer is a new AI tool designed to assist patent litigators with Section 101 patent eligibility analysis. Section 101 is often a decisive factor in patent litigation, and one of the quickest ways to win or lose a case, yet it is also one of the most difficult to navigate. Key concepts lack clear definitions, courts apply the same test differently across similar inventions, and the analysis is precedent heavy. It is an area of law that is time-consuming and costly. The new Patent Claim Eligibility Analyzer aligns with how courts approach Section 101. The tool quickly analyzes patent claims, surfaces highly relevant precedents, and explains why those cases matter. It provides a faster, more consistent, precedent-backed starting point to support attorney judgment.
