United States Federal Circuit

In a patent dispute involving the invalidity of multiple patent claims relating to certain types of computer modems and methods of identifying modems, judgment by district court is affirmed in part and reversed in part where: 1) court properly held that right to enforce relevant patents was extinguished by patent exhaustion as such patents had been duly licensed; and 2) court correctly granted summary judgment on the invalidity of some claims while improperly granting summary judgment on others.
