Default Nvidia and AMD Sued Over Power Management - 04-09-2012, 20:48 | posts: 3,107

More lulz from the US patent system:

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 in question describes the idea to control electricity flow via on and off switches "between the co-resident functional circuit I/O nets and the integrated circuit I/O pads" as well as between internal and external ICs. The basic idea covers power being routed "from an external power supply through the power gating means to the internal functional circuit" using switches and a second electrical signal is being employed to control "the coupling action in the power gating means."
