Almost two months after Apple filed a patent complaint against HTC, the Taiwanese handset maker says it has a patent beef with Apple too.
On Wednesday, HTC accused Apple of infringing on five patents related to its mobile technology, and it has asked the International Trade Commission to stop the import and sale of Apple's iPad, iPod, and iPhone.
The complaint, which can be viewed below, states Apple that is infringing on five patents related to general hardware and software used to implement directories in mobile phones and power management in mobile devices. It's notable that at least one of the patents was just granted Tuesday, a day before the ITC complaint was filed.
"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," Jason Mackenzie, vice president of HTC North America said in a statement. "We are taking this action against Apple to protect our intellectual property, our industry partners, and most importantly, our customers that use HTC phones."
HTC's filing is a follow-up to Apple's accusation in early March that HTC phones infringe on 20 Apple patents. CEO Steve Jobs accused HTC of stealing Apple's technology for the iPhone.
"We can sit by and watch competitors steal our patented inventions, or we can do something about it," he said at the time.
HTC accusing Apple of infringing on some of its patents is a fairly standard defense in these types of cases. Apple and Nokia are engaged in a similar legal squabble right now. After Nokia accused Apple of illegally using 10 of its patents in the iPhone technology in October, Apple came back in December, complaining of Nokia "stealing" 10 of its patents. Last week, Nokia broadened the scope of its accusations against Apple to include the iPad 3G.
