The device maker is asking the International Trade Commission (ITC) to halt all sales and import of the Apple iPhone 3G/S, iPad and iPod Touch.
Says HTC in a press statement: "As the innovator of the original Windows Mobile PocketPC Phone Edition in 2002 and the first Android smartphone in 2008, HTC believes the industry should be driven by healthy competition and innovation that offer consumers the best, most accessible mobile experiences possible. We are taking this action against Apple to protect our intellectual property, our industry partners, and most importantly our customers that use HTC phones."
From their end, Apple is looking for monetary damages and an injunction that would block HTC from selling most of their smartphones in the U.S.
