SAN FRANCISCO — As a Northern District patent battle heats up, Radware is trying to disqualify IP litigator Morgan Chu and others at Irell & Manella from representing rival networking firm A10 Networks.

In a motion filed Friday, Radware argued that the Irell team has an ethical conflict because Chu and others have previously advised the company. Representing Radware in at least two matters, Irell gained confidential information about Radware’s products, financing and decisionmaking, the Israeli company claimed in the motion for disqualification.
