A mystery plaintiff called Imperium (IP) Holdings, Inc. has hit Apple, along with a bunch of other smartphone makers, with a lawsuit over patent infringements relating to imaging technology.
The other defendants in the crosshairs with Apple are Kyocera, LG Electronics, RIM, Sony Ericsson, Nokia and Motorola.
According to Patently Apple, the five patents infringes are:
- Patent 6,271,884: Image Flicker Reduction with Fluorescent Lighting. The assignee on this patent is noted as being Conexant Systems, Inc. This patent seems to cover any and all devices incorporating image sensors, as the illustration that forms part of the patent shows:

- Patent 6,838,715: CMOS Image Sensor Arrangement with Reduced Pixel Light Shadowing.
- Patent 7,064,768: Bad Pixel Correction While Preserving Features
- Patent 7,109,535: Semiconductor Device for Isolating a Photodiode to Reduce Junction Leakage.
Little is known about the plaintiff, Imperium (IP) Holdings, Inc. other than it is a Cayman Islands corporation with a simple "place of business" in New York. The only companies mentioned as assignees on the patents are Conexant and ESS Technology. No word on how these companies are linked to Imperium (IP) Holdings.
