Intellectual Property Litigation

We have experience in a variety of matters involving issues of patent law, copyright, trademarks and trade dress.  For example, we have been extensively involved in defending the Lemelson Foundation, which controls the world’s largest privately held portfolio of patents, as well as the heirs of the famous inventor Jerome Lemelson.  The Foundation and Mr. Lemelson’s heirs have been repeatedly sued for hundreds of millions of dollars on various legal theories.  All claims have been successfully defended and dismissed.  See, e.g., United States Metals v. Lemelson Medical 106 P.3d 1265 (Nev. 2002); Syndia Corp., et al. v. Lemelson Medical, Education, and Research Foundation, Limited Partnership, 165 F.Supp.2d 728 (N.D.Ill. 2001).  In other matters we have, for example, prosecuted cases to protect trade secrets; defended against claims of trade dress infringement; and responded to patent infringement claims with substantial antitrust counterclaims on which our clients ultimately prevailed.
