Angela C. Whitesell

Angela C. Whitesell is an Of Counsel attorney at DLA Piper US, specializing in intellectual property litigation. Her practice encompasses both life science and technology matters. Whitesell's background includes significant experience with Hatch-Waxman (ANDA) and BPCIA litigation, gained during her tenure as a law clerk for the U.S. District Court, District of Delaware, where she drafted relevant opinions and orders for multiple judges, including Hon. Judge Colm F. Connolly and Hon. Judge Richard G. Andrews.

Whitesell primarily represents operating companies, often in defensive postures against patent assertions. While her tracked appearances include one on the defendant side, she also represented Hewlett Packard Enterprise Company as the plaintiff in a declaratory judgment action against Intellectual Ventures I LLC and Xenogenic Development Limited Liability Company in the District of Delaware in December 2022. In that case, the court denied the defendants' motion to dismiss for lack of subject matter jurisdiction, allowing Hewlett Packard Enterprise's action concerning patent infringement allegations to proceed.

Her professional profile does not specifically detail regular appearances in PTAB or IPR proceedings. Whitesell is admitted to the Delaware bar and is also admitted to practice before the U.S. Court of Appeals for the Federal Circuit and the U.S. District Court for the District of Delaware. She earned her J.D., magna cum laude, from Widener University School of Law and holds a B.A. from Sarah Lawrence College.
