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.
