Hewlett-Packard has filed a patent suit against Gateway, the suit alleges that Gateway infringed certain HP patents and has refused to properly compensate. Although monetary figures have not been specified yet, HP seeks compensation for past patent infringements and a structure for compensation going forward. The suit centers on six patents related to PCs, including a patent on 1-inch notebook computers and power management. But the lawsuit could be expanded to cover more, because HP has about 6,000 patents related to PCs, according to an HP representative. The company has about 21,000 patents worldwide.
