Mr. Zelley has experience representing both sides in patent infringement cases and has specifically represented patent owners in Abbreviated New Drug Application (ANDA) litigations. While the single tracked case indicates a defendant-side role, his professional profile confirms a balanced practice.

Notable among his case work, Mr. Zelley was part of a Drinker Biddle team that secured a dismissal without prejudice for Vital Pharmaceuticals, Inc., in a three-year-long patent infringement suit in the U.S. District Court, Southern District of Florida. The case involved a patent related to a dietary supplement product. He has been recognized as a top patent professional in the IAM Patent 1000 in multiple years.

He is admitted to the Delaware bar, the U.S. Patent and Trademark Office, the U.S. Court of Appeals for the Federal Circuit, and the U.S. District Court for the District of Delaware. Mr. Zelley earned his law degree from George Washington University Law School.
