Over the past 19 years of practice, Tom Selby has concentrated his practice in two (usually) distinct areas: patent litigation and professional liability defense.  He serves as Co-Head of the firm’s Patent Litigation practice group working on patent and licensing litigation, and at the same time represents accounting firms in major regulatory and trial matters.

Tom has represented clients in intellectual property disputes over software, biotech, pharmaceutical, medical device, and communications technologies. He served as lead counsel to Pfizer at a bench trial over the major cancer treatment Sutent®, in which Pfizer prevailed on all issues.  In 2014, in addition to ongoing matters for Pfizer, he represented Intel in trade secrets litigation, and Novartis subsidiary Alcon in Hatch-Waxman litigation.  Tom was lead counsel for ACell, Inc. in successful inter partes interference proceedings, that followed successful federal court litigation.  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 2015-2018 editions of LMG Life Sciences.

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 35 litigation and regulatory matters.  Tom served as co-lead defending accountants in litigation over the Madoff fraud, and in the collapse of the Sentinel investment firm, in which the principal was convicted in what prosecutors called one of the largest criminal fraud cases ever to come out of Chicago.  Although the vast bulk of these accounting matters involved GAAP and GAAS disputes, Tom has also handled litigation involving tax services, securities, non-competition, and employment/whistleblower issues.  Tom has represented accountants and auditors in investigations by the Securities and Exchange Commission, Department of Justice, the federal Office of Inspector General, the Commodity Futures Trading Commission, and the United States Congress.

In his pro bono practice, in 2014 Tom was lead defense counsel in a felony criminal trial in the District of Columbia in which the jury returned a not guilty verdict on all counts.  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.  He has also handled matters through the firm’s partnership with the Montgomery County Public Defender’s office, including an additional criminal jury trial.

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, and their son.  Their daughter attends the University of Virginia.
