Nomadix, Inc. v. Guest-Tek Interactive Entertainment Ltd., (C.D. Cal.; 9th Cir.; PTAB)
In a first case, obtained a multimillion dollar jury award for client Nomadix for Guest-Tek’s breach of its royalty obligations under a patent license agreement.

Obtained permanent injunction requiring Guest-Tek to withdraw inter partes review (IPR) challenges to Nomadix’s patents and prohibiting Guest-Tek from filing more IPR challenges. Argued the appeal to the Ninth Circuit and successfully defended the district court’s finding of breach and permanent injunction.
