  • (Northern District of California). Represented EchoStar, the owner of the DISH Network, in a closely watched patent infringement case involving a number of patents purportedly relating to digital media transmission. EchoStar was one of multiple defendants in this multi-district patent infringement action involving distributed audio/video information and whether major U.S. satellite and cable television providers infringe Acacia patents related to video-on-demand (streaming video) technology. We assumed a leadership position in developing the defenses against these patents, which, if afforded the broad construction assigned to them by the patentees, could have far-reaching effects on numerous forms of digital transmission used in many different industries. After multiple rounds of claim construction proceedings, defendants prevailed on summary judgment of noninfringement and invalidity of all patents, which was affirmed by the Federal Circuit in 2010.
