US Trade Commission investigates Blu-ray patent

While we hear Sony has kept the party going non-stop since HD DVD's demise, the US International Trade Commission has stepped in as the role of the party pooper. Gertrude Neumark Rothschild, a former Columbia University professor, has filed a complaint with the ITC over what she says is infringement for patent she owns on certain light-emitting and laser diodes contained in Blu-ray players and other electronics.

The commission has voted to investigate the claim, though they have "not yet made any decision on the merits of the case." Rothschild's complaint lists over 30 companies, including Sony, Samsung, Toshiba and Nokia.
