AMD and NVIDIA sued for possible Power Management technology patent infringement

[caveman-jim]

Tom's Hardware Guide reports on a lawsuit brought against AMD and NVIDIA for their innovative new power management technologies, that might not be that new:

Power Management Solutions, a Frisco- Texas-based company with no traceable corporate history, claims that it is entitled to damages relating to patent number 5,504,909, which the company says is infringed by AMD and Nvidia.

The patent, titled "Power management apparatus collocated on the same integrated circuit (IC) as the functional unit that it manages" was filed by Electronics Products Company in January 1994 and approved by the USPTO in April 1996. Power Management Solutions claims it has the rights to the patent, even if the USPTO did not list Power Management Solutions as the rightful owner at the time of this writing. Intel and Freescale were sued by Power Management Solutions over the same patent back in August of last year.
