REPRESENTATIVE MATTERS

MGA’s LOL dolls gross over $5 billion dollars annually and is MGA’s most popular product. MGA sued OMG GIRLZ for declaratory relief and a finding that it is not infringing on OMG’s mark. OMG filed a counter-claim against MGA and its founder for $100 million alleging violation of the Lanham Act. The jury returned a complete verdict in favor of MGA in less than two hours.
