Taiwanese smartphone manufacturer HTC Corp. said Wednesday it has filed a new lawsuit against Apple Inc., accusing the iPhone maker of infringing on three of its patents. 

In the complaint filed Tuesday with the U.S. International Trade Commission (ITC) and the U.S. District Court of Delaware, the Taoyuan, Taiwan-based company claimed Apple's Mac computers and iPhone, iPad and iPod product lines had all violated HTC patents. 

HTC General Counsel Grace Lei said the action was taken to protect HTC's intellectual property, commercial partners and consumers who use HTC phones. 

"Apple needs to stop its infringement of our patented inventions in its products," Lei said in a statement. 

The patents cover a range of functionality on mobile devices, including the Wi-Fi capability that allows users to connect multiple devices through a wireless network, and the processor communication technology that integrates a PDA and a cellular phone into a single device.
