Representative Matters

  • Successfully represented Asahi Glass Company, Ltd., a Japanese glass manufacturer, and its subsidiary AFG Industries, Inc., a U.S. glass manufacturer, claiming patent infringement by Cardinal IG Co. of Asahi and AFG’s jointly owned patent relating to thin film low-emissivity coatings typically used in double-pane windows. After a four-day trial, the Federal District Court Judge granted judgment to Asahi and AFG on the issue of infringement. Thereafter, the jury returned a verdict of more than $25.1 million to which the court awarded prejudgment interest of more than $18.5 million, for a total of more than $43.7 million in damages. AFG and Asahi Glass v. Cardinal IG, No. 2:96-cv-244 (E.D. Tenn. 2005).
  • Successfully represented Toshiba at trial, obtaining a holding that competitor Loral Fairchild’s early Charge-Coupled Device (CCD) patent was invalid and not infringed. Loral Fairchild, Corp. v. Matsushita Elec. Indus. Co., Ltd., No. 91-5056(S.D.N.Y. 2001).
  • Representing client Buffalo Inc. and its subsidiary Buffalo Technology (USA) Inc., successfully appealed grant of summary judgment and permanent injunction in favor of CSIRO in a high-profile patent infringement case involving Wi-Fi technology relating to the transmission of wireless signals.
