Drexler Technology v. Dolby Laboratories, Inc., et al.

This case, filed in the Northern District of California, involved patent infringement claims asserting that Dolby Digital sound-on-film technology infringed patents held by the plaintiff, Drexler Technology Corporation.  In addition to defending Dolby Laboratories, also represented a number of major entertainment companies (including Walt Disney Pictures, Fox, MGM, Universal Studios and Columbia Pictures) in this action.  After obtaining a claim construction (“Markman”) order supporting virtually every claim construction position advocated on behalf of our clients, the Court entered summary judgment in the defendant's favor on grounds of non-infringement and patent invalidity.
