Represented VMware and EMC in a suit, initially filed in the Eastern District of Texas, relating to cloud computing. The plaintiff, a non-practicing entity, alleged infringement of a portfolio of patents by most of the major cloud computing companies.

We ultimately convinced the Eastern District of Texas to transfer the case to California, and convinced the Northern District of California to stay the case pending the proceedings. The Patent Trial and Appeal Board subsequently invalidated all challenged claims, and the Federal Circuit affirmed.
