This past week, Delaware Chief Judge Colm F. Connolly heard oral argument related to motions for a preliminary injunction against Bell Semiconductor, LLC (Bell Semic), which has been filing multiple cases in various districts targeting the provision of semiconductor devices that are manufactured using certain design tools provided by Cadence, Synopsys, and/or Siemens. Cadence and Synopsys together filed a declaratory judgment (DJ) action in Delaware, as Siemens separately has, asking Judge Connolly to stop Bell Semic from pursuing its customer suits, filed both in district court and before the International Trade Commission (ITC). The ITC responded to those motions by intervening to oppose any interference with the conduct of its investigations, and Bell Semic responded to the DJ complaints themselves with motions to dismiss for lack of subject matter jurisdiction. Entries on the case docket provide clues as to how the hearing went.
