LG Electronics, Inc. v. Interdigital Communications, Inc., C.A. No. 9747-VCL (Del. Ch. Aug. 20, 2014).

This decision applied the familiar first-filed rule, also known as the McWane Doctrine, to a first filed arbitration claim. The court dismissed a complaint that sought injunctive relief notwithstanding that the same issue had been presented in a previously-filed arbitration between the parties.  This appears to be the first time that the first-filed rule was applied (in Delaware) to bar a suit as a result of that doctrine, when a previously-filed arbitration proceeding between the same parties involving the same dispute was already pending, as compared to a prior suit filed in court.
