A three-judge federal appeals panel is weighing whether a Missouri company violated a settlement agreement with a Kentucky-based competitor in advertisements about a dietary supplement.

Judges from the U.S. 6th Circuit Court of Appeals in Cincinnati quizzed attorneys for Lexington-based Cogent Solutions Group and Hyalogic, a Missouri company, about the specifics of an agreement meant to keep Hyalogic from directly criticizing a supplement called Baxyl.

Baxyl is the brand name for a dietary supplement advertised for use in joint function.
