Juniper Networks v. Toshiba America Information Systems. Mr. Kagan has represented Juniper Networks in a number of intellectual property matters, including this protracted patent infringement dispute with Toshiba. In response to a motion filed by Juniper Networks shortly before trial, the Court issued a sanctions order against Toshiba that, among other things, barred Toshiba from calling its expert witness on non-infringement and severely limited Toshiba’s time for its opening statement and closing argument. The case settled in late 2007, shortly after the Court issued the sanctions order.
Ultratech Stepper v. ASML. Mr. Kagan served as trial counsel for ASML, one of the world’s leading suppliers of semiconductor manufacturing equipment, in this patent infringement case. While both of ASML’s competitors (who were initially co-defendants in this action) entered into substantial settlements with the plaintiff, ASML elected to litigate. After a four-week trial – and with less than one day of deliberation – the jury found the plaintiff’s patent invalid on multiple grounds. The Federal Circuit affirmed the jury’s verdict in its entirety. The Los Angeles and San Francisco Daily Journal's recognized this victory as one of the top ten defense verdicts of 2005.
Aviza Technology v. ASML. Mr. Kagan served as lead counsel for ASML in this arbitration, in which the claimant accused ASML of fraud and negligence. After a one-week hearing, the Arbitrator found in favor of ASML on all causes of action, and determined that ASML was entitled to recover its litigation expenses, including attorneys’ fees.
Sharper Image v. Ionic Pro. Mr. Kagan defended a patent and trademark case brought by Sharper Image against retailers and manufacturers of air purifiers that competed against its flagship "Ionic Breeze." This case settled after Sharper Image’s claims of trade dress and design patent infringement were dismissed on summary judgment.
Stac Electronics v. Microsoft. Mr. Kagan represented Stac Electronics, a small software company, in a patent infringement suit it brought against industry giant Microsoft. After an extensive trial, the jury awarded Stac Electronics $120 million in patent damages. Stac also obtained a worldwide injunction against the sale of Microsoft’s operating system.
Novellus Systems v. Applied Materials. Mr. Kagan represented Novellus Systems, a manufacturer of semiconductor manufacturing equipment, in a patent infringement lawsuit filed against it by industry-leader Applied Materials. Over a period of seven years, each of the patents Applied Materials had asserted against Novellus was declared invalid, held not to be infringed, or withdrawn from the case. The parties then reached a settlement of the case, which involved a payment from Applied Materials to Novellus.
