Hewlett-Packard Co. was cleared by a jury of claims it illegally monopolized the market for inkjet printer cartridges, and the No. 2 computer manufacturer won a $2-million verdict against a rival in a related intellectual property dispute. An eight-member federal jury in San Jose unanimously agreed with Hewlett-Packard's claims that Nu-Kote International Inc., the largest independent producer of aftermarket printer supplies, engaged in patent and trademark infringement and false advertising. Capping a six-week trial, the jury also rejected antitrust claims that Nu-Kote had brought against Hewlett-Packard. "It has taken 4 1/2 years to resolve our issues with Nu-Kote satisfactorily, but we are pleased with the outcome," said Hewlett spokesman Antonio M. Perez. "Our ability to compete is directly threatened by the misuse or misappropriation of our intellectual property." Shares of Hewlett closed down $7.31 at $105.25 on the New York Stock Exchange.
