Smartphone Litigation
Member of the team that successfully tried a high-profile smartphone case leading to a jury verdict of over $1 billion.
Confidential Life Sciences Arbitration
In 2011, Morrison and Foerster scored a complete victory for our client in high-stakes arbitration. Our client, a multi-national corporation in the medical field, was accused of infringing a number of its competitor's patents. In addition to the direct product competition at the heart of the dispute, the potential damages were well into the nine-figure range. The dispute was subject to an arbitration clause, and a three arbitrator panel was selected. After the parties conducted fact and expert discovery, they proceeded to a two-week evidentiary hearing. Our client prevailed on either non-infringement or invalidity on every patent, an unusually complete victory for one side in the arbitration context.
Nazomi v. Sling Media, Inc.
(Northern District of California). Represented Sling Media in a patent infringement action involving Java hardware acceleration. The firm handled claim construction and summary judgment briefing and arguments, and obtained summary judgment of non-infringement in favor of Sling Media.
Northpoint Technology v. DISH Network/EchoStar
(Western District of Texas and U.S. Court of Appeals for the Federal Circuit). Northpoint Technology filed a lawsuit against DISH and DIRECTV claiming that the defendants infringed a patent directed to processing signals from the satellite dish. Working in conjunction with counsel for DIRECTV, we developed claim construction positions on which we could argue invalidity and filed separate motions for summary judgment based on those arguments. The District Court adopted our key proposed constructions and granted summary judgment of invalidity.
