SAN FRANCISCO, June 28, 2010 - Apple fired another volley against HTC, the the Taiwainese smart phone hardware makers last week when it accused the firm of infringing four of its patents covering the iPhone.
HTC makes the smartphones that use Google's Android operating system.
The suit, filed in federal district court in Delaware, accuses HTC of infringing patents that cover the way a user interacts with a device, and that cover the way the device conserves power.
Apple is asking the court to block the sale of the phones, for damages and attorneys' fees.
Apple also sued HTC at the International Trade Commission this March, charging that the company had violated 20 of its patents.
