Graphics company Nvidia said that 3Dfx's action on alleged patent infringement is "nuisance litigation". The company said it will vigorously defend itself against the action and had not yet received a formal complaint but only a copy of a 3Dfx press release. Jen-Hsun Hang, CEO and president of Nvidia, said: "In light of recent admissions by 3Dfx, we can only speculate that they are turning to legal remedies in an attempt to stay profitable." He said that 3Dfx should instead be addressing their core market issues of channel saturation for older products and uncertain demand for their latest product. He continued: "While we have not yet been served with the complaint, Nvidia has examined the patent and believes there is no infringement by the Riva TNT [graphics processor]. Nvidia intends to defend itself against this nuisance litigation." ® Click for more stories
