Apple sued over iPhone keyboard

SP Technologies has sued Apple claiming that it came up with the idea of a touch-screen keyboard long ago.

The first iPhone lawsuit might have been somewhat laughable, but the second one may be a little more serious.

An outfit called SP Technologies has sued Apple over the touch-screen keyboard at the heart of the iPhone, claiming Apple is infringing on a patent held by SP Technologies for a similar keyboard. AppleInsider dug up the SP patent filing from 2000, which claims the company developed a "method of providing a user interface for receiving information from a user using a user immutable graphical keyboard linked to an input area."

Patent suits, of course, are a dime a dozen, and Apple's not exactly the first company to ever use a touch-screen style input method. But this one will probably require more effort to defend than the iPhone battery suit filed a few weeks ago. The suit was filed Thursday in Tyler, Texas, which has become the destination of choice for patent suits these days.

An Apple representative did not immediately return a call seeking comment, but it's unlikely Apple would have much to say at this stage.
