Sony Part Of Blu-Ray Patent Investigation

The U.S. International Trade Commission is reportedly looking into patent infringement allegations related to Blu-ray disc players and other products, and has included Sony in its investigation.

According to Reuters, the Commission has said its investigation encompasses "short-wavelength light-emitting diodes and laser diodes used in such electronics as handheld mobile devices, traffic lights and high-definition DVD players."

The investigation was reportedly precipitated by a complaint filed in February by Gertrude Neumark Rothschild, a Columbia University Professor Emeritus, who says that a variety of U.S. imports infringe on her patent and should be blocked.

Patent laws really need to be changed so that you need a working sample of your patent in order for it to be valid.

If she's got the blue prints written up and dated with the patent certificate

she's got every right to do what she wants

im sure sony would be all up anyone elses ass for using a little of there technology

so its all fair game if you ask me
