Representative cases

TrafFix Devices, Inc. v. Marketing Displays, Inc., 532 U.S. 23 (2001). Authored and filed an amicus brief filed in the Supreme Court on behalf of the American Intellectual Property Law Association (AIPLA) in support of the position that the owner of an expired patent cannot continue to protect the subject matter of that expired patent as trade dress; the patented feature enters the public domain when the patent expires. In a unanimous decision, the Supreme Court agreed, holding that a product feature that is functional cannot serve as a trademark, and a patented product feature is presumed to be functional.
