Covington’s Patent Office Trials practice draws upon the expertise of two former Patent Trial and Appeal Board (PTAB) Administrative Patent Judges, the firm’s deep bench of patent litigators with expertise in complex, multi-forum patent disputes and appeals, and Covington’s long history of success in reexamination proceedings before the U.S. Patent and Trademark Office (PTO). No other PTAB trial team offers Covington's combination of experienced PTAB litigators and PTAB insiders.

Covington has handled nearly 200 PTAB proceedings for petitioners and patent owners, many through final decision. Covington attorneys represent clients in all fields of technology, and regularly advise clients on combined litigation and PTAB strategies.

The practice is led by Peter Chen in Palo Alto, and David Garr in Washington. Mr. Chen is a former Lead Administrative Patent Judge (APJ), as well as a first-chair patent litigator with over three decades of trial experience. He presided over more than 200 PTAB proceedings while serving as a PTAB judge from 2013 to 2017 at the West Coast Regional Office of the PTO. Mr. Garr is an experienced patent litigator who has handled over 50 PTAB proceedings, and specializes in complex patent disputes spanning U.S. District Courts, the PTO, and the ITC.

This unique combination of Patent Office and litigation talent, on both the East and West Coasts, puts Covington’s clients in position to successfully undertake Inter Partes Review (IPR), Covered Business Method (CBM), and Post Grant Review (PGR) proceedings, while efficiently managing simultaneous litigation.
