Compco Corp. v. Day-Brite Lighting, Inc., 376 U.S. 234 (1964). is a 1964 United States Supreme Court decision that was a companion case to Sears v. Stiffel, which the Court decided on the same day. Like Sears, Compco held that state law that, in effect, duplicated the protections of the US patent laws was preempted by federal law.
