A two-year-old lawsuit accusing Metaswitch of infringing on seven patents owned by Genband recently came to an end with an East Texas jury awarding the plaintiff more than $8 million in damages.

Marshall federal court records show that a verdict form submitted on Jan. 15 during a weeklong trial confirmed Genband was successful in proving Metaswitch committed infringement of United States Patent Numbers 6,791,971; 6,885,658; 6,934,279; 7,995,589; 7,047,561; 7,184,427; and 7,990,984.

Metaswitch, in turn, failed to prove that Genband’s claims were invalid, per the four-page document.

Genband filed the patent infringement suit against Metaswitch on Jan. 21, 2014.
