Tony Sheh litigates primarily on behalf of technology companies with complex patent disputes in the pharmaceutical and biotech areas.  Tony has represented clients before federal and state courts, before arbitral panels, and in the U.S. Patent Trademark Office, where he is a registered patent attorney. 

Several of Tony’s cases have focused on Hatch-Waxman district court litigation with co-pending inter partes review proceedings before the Patent Trial & Appeal Board.  In addition to his experience in patent disputes, Tony has represented clients in antitrust disputes, as well as individual clients in local and federal courts in the District of Columbia.

As a former patent examiner, Tony received his law degree from Georgetown Law where he served as an editor of the Georgetown Law Journal and an Executive Editor of the Annual Review of Criminal Procedure while working as a patent agent.  Prior to law school, Tony received engineering degrees from the Johns Hopkins University and the University of Michigan, and was a research assistant in the areas of cellular and carbohydrate engineering and computational soft-matter simulation.  After law school, Tony clerked for the Honorable Thomas M. Hardiman on the U.S. Court of Appeals for the Third Circuit, and the Honorable Timothy B. Dyk on the U.S. Court of Appeals for the Federal Circuit.  Tony joined Williams and Connolly in 2017 and is a member of the W&C Families Committee.

Representative Experience

Though all cases vary and none is predictive, Tony's experience includes:

  • Counsel for Merck in Hatch-Waxman patent litigation involving Januvia® (sitagliptin), in both the district court and in co-pending IPR proceedings, in which the PTAB upheld all claims of the patent-at-issue.  
  • Lead counsel in a pro bono matter representing six families left homeless in the aftermath of an apartment fire in Northwest DC.  The Washington Council of Lawyers featured the work of W&C and the Children’s Law Center in resolving this matter as part of their Pro Bono Week 2020 presentation.
