Professional Real Estate Investors, Inc. v. Columbia Pictures Industries, Inc.

Columbia Pictures and other studios (plaintiffs) sued PRE (defendant), a hotel operator renting movie videodiscs to guests, for copyright infringement; PRE counterclaimed that the suit itself was sham litigation intended to restrain competition and thus outside Noerr-Pennington antitrust immunity, but the courts below found the studios had probable cause for their copyright claim and granted the studios summary judgment on the antitrust counterclaim.
