NEWS: Consumer electronics firms investigated for patent infringement

Reuters has reported that virtually every major player in the home entertainment market is under investigation for patent infringement.

A Columbia university professor has claimed that she was responsible for the tech breakthrough that allows the production of blue and ultraviolet LEDs.

Emeritus professor Gertrude Neumark Rothschild filed the complaint last month and the US based International Trade Commission has recently picked up the case for investigation.

Many products from Blu-ray players to mobile phones use the technology and, along with Sony, Toshiba, Samsung, LG and Panasonic are all being investigated.

While the investigation isn't of immediate concern to consumers, the outcome could see manufacturers paying royalties to use blue and ultraviolet LEDs and, possibly, a decline in their use within future products.
