Karen focuses on litigation that crosses the boundaries between traditional legal practices, and therefore requires inventive and strategic approaches. These solutions, tucked in the creases between law and industry, are why leading technology and Fortune 500 companies hire Karen to resolve their most complex litigation matters.
Over the past 36 years, Karen has first-chaired state and federal trials, and arbitrated more than a dozen disputes. She has managed intellectual property and commercial disputes for companies such as Oracle, NVIDIA, Netflix and VMWare.
In addition to her legal background, Karen’s relationship management skills give her clients a significant advantage. She knows how to pull together and lead the best team, from multiple disciplines within Orrick, and often involving multiple law firms. Able to unite what were, and will be, competing firms into a single powerful unit takes a special type of leadership, one which Karen has demonstrated time and again.
