My focus

My litigation practice focuses on resolving patent disputes across a wide range of technologies, including printed circuits, enterprise software, light-emitting diodes, graphical user interfaces, lithium-ion batteries, and others. I have experience successfully litigating complex international disputes with parallel proceedings in multiple jurisdictions and countries. I have helped prepare successful technical arguments in numerous inter partes review (IPR), post-grant review (PGR), and covered business method (CBM) proceedings.

My practice also encompasses all aspects of patent prosecution, including technical analysis, drafting applications, office action responses, reissue and continuing applications, appeal practice, and managing local counsel for foreign office actions.
