Won a “record-setting” $293M verdict for Monster Energy Company against rival beverage company Vital Pharmaceuticals, Inc. in a false advertising, tortious interference, and trade secret case after a monthlong trial. The jury found Vital Pharmaceuticals Inc. and its CEO falsely advertised the “super creatine” ingredient of its billion-dollar Bang energy drink. The verdict is believed to be one of the largest, if not the largest, Lanham Act awards ever. (See “Monster Energy wins $293 mln false-advertising verdict against rival Bang,” Reuters; “Monster Wins $293M Verdict Against VPX In False Ad Trial,” Law360; “Monster Energy Wins $293 Million False Ad Award Over Bang,” Bloomberg Law).

Won one of “the largest-ever U.S. trademark awards” (Reuters) for Monster Energy Company against rival beverage company Vital Pharmaceuticals, Inc. Following a two-week trial, the arbitrator held that VPX’s Bang Energy does not contain advertised muscle-building creatine and infringed on “Bang” trademark. In the significant ruling, the arbitrator awarded Monster and Orange Bang $175 million in damages, nearly $10 million in attorney’s fees and costs, and a 5% royalty on all future sales of Bang Energy (with over $1.5 billion in annual sales). (See “Monster asks court to enforce $175 mln award against Bang Energy maker,” Reuters; “Monster, Orange Bang Win $175M Against Rival In Arbitration,” Law360).
