ADC Technology launched a lawsuit against several technology companies claiming they infringed on its patents. Filed in the District Court for the Northern District of Illinois, ADC claims that Apple, LG, U.S. Cellular, Mobilecomm, Nokia, and Exedea are all infringing on three of its patents. According to the lawsuit documents, the patents in question are “the ‘136 Patent,” “the ‘605 Patent,” and the “the ‘361 Patent.”

All three patents describe a “Portable Communicator.” The abstract for the patents reads:

This communicator makes it possible for the user to do telephone, facsimile, and data communication at any location. On a pen input device, a space eye 2, a telephone control system, a facsimile control system, and a data transmission system are mounted. All of them are operated by an input pen 55 or the space eye 2. The pen input device is connected to a wireless telephone equipment 7, and can be connected to a desired party through the public communication channel. In order to make the most of the equipment of a GPS user, the GPS user device 8 is connected to the pen input device 3. The current location of the GPS user is found through the GPS user device 8, and the data on the current location is transmitted to the party. Further, to make this communicator usable in any country, it is provided with means to connect it to a wireless telephone network of an individual service area of the country.

ADC is claiming that devices that infringe on its patents include:

• LG: Incite, enV Touch, Chocolate Touch, Dare, Xenon, Tritan, and Bliss
• HTC: TouchPro2, DroidEris, Hero, and TouchDiamond2
• Apple: iPhone
• Nokia: N97, N900, 5530, 5800, 3606, 6350, 6205, and 2705.

A hearing has been set for April 23, 2010.
