Sony Blu-ray Under Patent Infringement Probe

Lucas123 writes "The US International Trade Commission said it will launch an investigation into possible patent infringements involving Sony's Blu-ray players and other technologies using laser and light-emitting diodes, such as Motorola's Razr phone and Hitachi camcorders. The investigation was prompted by a complaint filed in February by a Columbia University professor emerita who says she invented a method of using gallium nitride-based semiconductor material for producing wide band-gap semiconductors for LEDs and laser diodes in the blue/ultraviolet end of the light spectrum. Her complaint asks the ITC to block imports of LED and laser diode technology from Asia and Europe. The total market for all types of gallium nitride devices has been forecast at $7.2 billion for 2009 alone."

    For everyone yelling 'patent troll,' realize that she has been trying to enforce her rights since at least 1995. She also seems perfectly willing to license the technology http://www.compoundsemi.com/documents/articles/cldoc/7121.html...

    I think that is how you're supposed to do things...

    "Clearly Sony developed this on their own, so you can't even say they stole it."

    Really? Given that her patent claim is 12 YEARS OLD, I don't think the word "clearly" means what you think it means.
