Tim is a former Vice Chief Administrative Patent Judge of the Patent Trial and Appeal Board and the current chair of the PTAB practice within O’Melveny’s Intellectual Property & Technology group.

Since joining O’Melveny in 2021, Tim has been counsel in over 100 inter partes review and reexamination proceedings, ranking consistently as one of the nation’s most experienced attorneys before PTAB and USPTO. Through his government and private sector work, Tim has extensive knowledge of patent law and practice and is particularly familiar with how PTAB rules, guidance, and decision-making fit within the USPTO’s evolving policy objectives. As a result, Tim is a recognized thought leader in PTAB practice and a frequent speaker on PTAB matters.

As a former Administrative Patent Judge with seven years of government service, Tim has also adjudicated hundreds of PTAB appeals and trials. As a Vice Chief Judge, he has advised on significant recent America Invents Act rulemakings, trial practice guidance, and internal PTAB operating procedures. And as a Senior Legal Advisor to the Director of the USPTO, Tim has advised the agency at large on important legal and policy issues.

As part of his practice, Tim participates in co-pending district court and US International Trade Commission matters to advise clients on how to manage the complex interactions between these tribunals and PTAB.

Prior to his government service, Tim was a partner at a large law firm, where he represented technology, telecommunications, health care, and life sciences clients in patent cases in district court, the US Court of Federal Claims, and the ITC. Prior to his legal career, Tim spent over a decade at major technology companies in both engineering and management positions, including at General Electric (Aerospace), Micron Technology, AT&T Bell Laboratories, and Lucent Technologies Bell Labs. Tim has bachelor’s and master’s degrees in electrical engineering from Drexel University and the University of Pennsylvania and a law degree from Georgetown, where he graduated with honors.
