The recent release and success of the iPad has sent Apple’s profits soaring. However, it appears that Apple may not be all smiles as it enters into a patent infringement suit leveled against it by the U.S. International Trade Commission and Elan Microelectronics. The Taiwanese company, represented by Paul Brinkman of Alston & Bird, is suing for patent infringement on “technology that is fundamental to multitouch user interfaces found in many computers and portable devices.” The suit targets both the iPhone and iPod Touch for their touch screen technology, which responds to input from multiple fingers, rather than one finger and the use of an additional button or cursor. Apple has yet to comment on the alleged infringement; however, as this is the third ITC case it has been involved in since January, it has a reason to remain mum.

In another matter filed today, Nokia filed suit against Apple in the Western District of Wisconsin. In this suit, Nokia is claiming that Apple’s iPhones and iPad violate patents it holds relating to antenna design. Interestingly enough, the ITC was mentioned in the complaint when Nokia made the claim that Apple is aware of at least one of these particular patents because it raised the patent in discovery requests served on Nokia in ITC Investigation No. 337-TA-701.
