Over the past 20 years of practice, Tom Selby has concentrated his practice in two (usually) distinct areas: patent litigation and professional liability defense. 

He is the former Co-Chair of the firm’s Patent Litigation practice group working on patent and licensing litigation. 

Over that same period Tom has represented national accounting firms in dozens of major trial, arbitration, investigatory and regulatory matters. 

Tom is a member of Williams & Connolly's Executive Committee.

On the patent side, Tom has represented clients in intellectual property disputes over software, biotech, pharmaceutical, medical device, and communications technologies. In 2019, he has served as lead counsel in patent or licensing matters for Dropbox, Pfizer, Danaher and Envista entities and others.  Tom has been recognized in the 2014-2019 editions of Washington, D.C. Super Lawyers Magazine under the category of Intellectual Property Litigation and has been listed as a “Life Science Star” in the 2015-2021 editions of LMG Life Sciences.  Since 2016, Tom has been recognized as a "Leading Patent Practitioners in Litigation (DC)" by IAM Patent 1000.  Since 2019, Managing Intellectual Property has recognized Tom as an "IP Star."

The other major focus of his practice is accountants’ liability:  for more than a decade, Tom has represented a national audit and accounting firm in over 40 litigation and regulatory matters.   Tom has handled litigation, arbitration, and regulatory matters involving GAAP and GAAS disputes, tax services, securities, non-competition, and employment/whistleblower issues.  Tom has represented accountants and auditors in investigations by the Securities and Exchange Commission, Public Company Accounting Oversight Board, Department of Justice, the federal Office of Inspector General, the Commodity Futures Trading Commission, and the United States Congress.

In his pro bono practice, Tom represents families separated at the border in asylum matters before US immigration authorities.  He has tried a felony criminal trial in the District of Columbia in which the jury returned a not guilty verdict on all counts, and handled matters through the firm’s partnership with the Montgomery County Public Defender’s office, including an additional criminal jury trial.  He represents a client on Louisiana’s death row in post-conviction proceedings, and successfully represented an inmate in habeas corpus proceedings appealed from the Louisiana Supreme Court. 

Tom was born and raised in Austin, Texas, and graduated from the University of Chicago in 1990.  Between college and law school, Tom spent six years working in Texas state and local government and politics. Tom received his J.D., with honors, from The University of Texas School of Law, where he was a member of the Texas Law Review and the American Journal of Criminal Law.  He joined Williams & Connolly in 1999.

Tom lives in Arlington, Virginia with his wife, Deirdre Doyle.  Their son is a student at the University of Virginia, and their daughter holds two degrees from UVA and is a school teacher in New York.
