Overview
Whether it’s enforcing patents or defending against infringement allegations, clients benefit from a nationwide practice that spans market sectors, a broad range of technologies, and a growing range of industries.
Enforcement and Defense
Unlike many law firms that focus primarily on defense work, we have successfully asserted numerous patents on behalf of our clients and effectively defended against patent infringement claims. Because of our deep experience helping clients secure patents through our renowned patent prosecution practice, clients gain an advantage from our ability to pursue both patent enforcement and defense.
In nearly every type of technology, our professionals who are engineers, computer scientists, Ph.D.’s, former patent office examiners, and judicial law clerks at both the district court and appellate level, bolster our litigation teams.
Tailored Litigation Strategy
From all-out war to leveraging results for an efficient resolution, we tailor our litigation strategy to your business objectives. We have offices in key geographic areas for patent litigation, including the San Francisco Bay area, Southern California, Seattle, New York, and Washington, DC.
ITC and Global Cases
We have extensive experience advocating for clients before the U.S. International Trade Commission (ITC), which enforces import bans against infringing products in fast-paced Section 337 investigations.
We also handle multi-forum litigation, for example enforcement cases in the U.S., UK, and Germany, through a coordinated litigation strategy.
