Appealed from: United States District Court for the Western District of Missouri Judge Dean Whipple

Opinion for the court filed by Senior Circuit Judge PLAGER. Additional remarks filed by Circuit Judge LOURIE.

In this patent case, Group One Ltd. (“Group One”) sued Hallmark Cards, Inc. (“Hallmark”) for infringement of two patents, U.S. Patent No. 5,518,492 (the “’492 patent”), directed to a machine for producing curled and shredded ribbon for decorative packaging, and U.S. Patent No. 5,711,752 (the “’752 patent”), directed to a method for producing the curled and shredded ribbon. Group One also claimed that Hallmark had earlier misappropriated its trade secrets regarding the curling and shredding machine and method. Hallmark counterclaimed for a declaratory judgment that Group One’s ’492 patent was invalid and unenforceable.
