HTC has just announced that they're counter-suing Apple for infringement, claiming Apple treads on 5 specific HTC patents.
“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,” said Jason Mackenzie, vice president of North America, HTC Corporation. “We are taking this action against Apple to protect our intellectual property, our industry partners, and most importantly our customers that use HTC phones.”
Apple originally sued HTC for patent infringement on April 2, citing 20 patents in a move widely speculated to be directed towards Google's Android platform in general. HTC had since agreed to license patents from Microsoft -- counter-intuitively -- for Android, again speculated to me a move directed towards Google.
Just like the Nokia vs. Apple suit and counter-suit, these types of suits can take months if not years to resolve, especially in the still forming smartphone space.
