Sony faces Blu-ray patent probe
9:30AM, Friday 21st March 2008
The US International Trade Commission is launching an investigation into 30 companies - including Sony - on possible patent infringements related to Blu-ray disc players and other products.
The commission says that the products involved are short-wavelength light-emitting diodes and laser diodes used in such electronics as handheld mobile devices, traffic lights and high-definition DVD players.
The move is based on a complaint filed in February by Columbia University Professor Emeritus Gertrude Neumark Rothschild, who is seeking to block imports into the US of a range of products that she said were infringing her patent.
Besides Sony, companies cited in the ITC announcement include Nokia, Motorola, LG Electronics and Matsushita.
A Sony spokesman says the company could not comment as the investigation is ongoing.
