Karl Mullen’s practice focuses on patent infringement litigation in the electronics and life sciences industries (including ANDA litigation). He has experience in all phases of patent litigation up through trial preparations, including motion practice, taking depositions, and working with and preparing expert witnesses. Mr. Mullen has also assisted in proceedings before the Patent Trial and Appeal Board (PTAB), including assisting with drafting inter partes review petitions.
Mr. Mullen has represented multiple leading technology and life sciences companies. For example, Mr. Mullen was a part of a team that took over a patent infringement case against Cisco Systems, Inc. days before the close of discovery and months before trial. Within months of taking over the case, the team obtained a pre-trial finding of non-infringement as to all asserted claims. That finding of non-infringement was upheld on appeal to the Federal Circuit.

During his time at the lab bench, Mr. Mullen’s work was published five times across four separate labs.
