HTC is fighting back against Apple's patent suit, saying it intends to defend itself.
Two weeks ago, Apple accused HTC of infringing 20 patents relating to the iPhone's user interface, underlying architecture and hardware.
"We can sit by and watch competitors steal our patented inventions, or we can do something about it. We've decided to do something about it," said Apple chief executive Steve Jobs at the time.
But, says HTC, the technology used in its smartphones is all its own.
"HTC disagrees with Apple’s actions and will fully defend itself," said Peter Chou, chief executive officer of HTC Corporation in a statement.
"HTC strongly advocates intellectual property protection and will continue to respect other innovators and their technologies as we have always done, but we will continue to embrace competition through our own innovation as a healthy way for consumers to get the best mobile experience possible."
The suit has been seen as a disguised attack on Google, for which HTC makes Android phones including the Nexus One. HTC is likely to issue a formal reponse to the suit in the next few weeks.
