Oh sure, she looks friendly enough. But don't let her matronly, argyle looks fool you. Retired Columbia University Professor, Gertrude Neumark Rothschild, is looking to extract some cold, hard cash from a who's who of Consumer Electronics giants. Otherwise, they can forget about importing their goods into the US. Rothschild's complaint filed with the US International Trade Commission (ITC) on February 20th claims that some 30 companies are violating a patent she owns for light-emitting and laser diodes. Today, the ITC has agreed to investigate the matter. It's worth noting that Rothschild has already successfully tested the judicial waters with lawsuits against Philips and others -- the Philips matter was settled out of court earlier this month. In other words, her case has legs. Still, we have very little confidence in the ITC's grasp of the matter when they name "HD DVD players (e.g., Blu-ray disc players)" as products to be probed. Full list of companies named in the complaint after the break.
