Recognized since 2013
Litigation - Intellectual Property
Mr. Angelis’ unique experience—as an intellectual property litigator who co-chaired the firm’s appellate practice and has an active appellate practice—allows him to craft and present especially persuasive and compelling arguments. He also provides clear and strategic advice to clients facing unsettled or complex legal issues, and he assists them in efficiently solving problems and minimizing risk.
Mr. Angelis has litigated patent matters before the U.S. International Trade Commission and U.S. District Courts in California, Delaware, Louisiana, Pennsylvania, Texas, and Washington. Mr. Angelis’ appellate practice focuses primarily on the Federal and Ninth Circuits, as well as the D.C. Circuit, where Mr. Angelis served as a law clerk. Mr. Angelis also regularly handles appeals in state appellate courts. Mr. Angelis’ appellate litigation experience spans a broad range of issues, including constitutional law, real property, intellectual property, Internet and cyber law, defamation, RICO, discovery sanctions, and asylum. At the trial court level, Mr. Angelis also litigates non-patent matters, but he focuses on intellectual property litigation—with a special emphasis on cyber and technology law—as well as Constitutional and real property litigation.
Mr. Angelis has received numerous awards and honors. He is listed in the Best Lawyers in America, and he recently was recognized by the King County Bar Association as Mentor of the Year. Earlier in his career, the King County Bar Association named him Outstanding Young Lawyer.
