“A company by the name of SmartPhone Technologies is suing Apple, AT&T and AT&T Mobility for patent infringement,” Jack Purcher reports for Patently Apple. “So what makes this patent troll case any different from the others? Well, interestingly, Smartphone Technologies states that they’re the ‘exclusive licensee’ of the six patents in this case that just happen to be heavy hitters from Palm and 3Com dating back to between 1997 and 2000.”

The six granted patents that are listed in this patent infringement case against Apple include the following Palm Inc, PalmSource Inc and 3Com patents:

• Granted Patent 6,976,217 Titled: Method and apparatus for integrating phone and PDA user interface on a single processor. From: PalmSource Inc. 2000
