The US International Trade Commission (ITC) has voted to investigate a patent complaint against select short-wavelength light emitting diodes, such as the ones used by Blu-ray players. The complaint was filed by Gertrude Neumark Rothschild of Hartsdale, NY, on February 20, 2008, and alleges that some aspects of Blu-ray technology infringes on patents.

Thirty companies, including Sony and other Blu-ray player manufacturers, are listed as respondents. The ITC investigation doesn't necessarily mean any foul play has been committed -- the ITC states they have "not yet made any decision on the merits of the case." This could be over quickly, or Sony can expect yet another long-haul legal battle over its technologies.
