Apple, RIM, Motorola sued for patent infringement

Apple is among seven companies being charged with patent infringement, according to court documents filed last Friday. All of the products allegedly infringing the patents are phones. The product named from Apple is the iPhone.

Filed in the Eastern District of Texas, Tyler Division, the lawsuit filed by Imperium Holdings claims that the seven companies infringe on five of its patents. Other companies named in the lawsuit are Kyocera, LG, Motorola, RIM, Nokia, and Sony Ericsson.

According to the lawsuit, the companies are charged with violating the ’884 patent which describes “An imager reduces lighting induced flicker by setting its pixel integration time to an integral multiple of the periods between peak intensity of the lighting. In one implementation, flicker is reduced in a 30 Hz frame rate camera capturing an image lighted with 50 Hz lighting by setting the integration time to approximately 10 ms, the period between lighting intensity peaks.”
The ’651 patent that describes “a solid state imaging device comprising a red pixel, a blue pixel, a first green pixel, a second green pixel, two analog-to-digital converters and a color interpolation circuit.”

The plurality of pixels includes a first pixel proximate an optical center of the array, and a second pixel proximate a peripheral edge of the array.”
The ’768 pantent that describes the “pixel correction system includes a dynamic range detection system that receives test pixel data and adjacent pixel data and determines whether the test pixel data is within minimum pixel characteristic data and maximum pixel characteristic data of the adjacent pixel data.”
Finally, the last patent mentioned in the lawsuit, the ’535 patent that describes “an improved semiconductor device that reduces reverse bias junction leakage in a photodiode by using a junction isolation region to isolate the photodiode from a trench isolation region. The improved semiconductor device improves image quality for different applications such as stand-alone digital cameras and digital cameras embedded in other imaging devices such as cellular phones and personal digital assistants.”
Imperium is asking the court for damages and an injunction against the companies to stop them from infringing on the patents.
