NVIDIA patented switchable graphics
Recently the U.S. patent and Trademark Office (USPTO) has granted a patent for Nvidia exchange between integrated graphics and dedicated graphics on a single computer, ie a technology called switchable graphics (switchable graphics) technology used in the Optimus/Synergy Nvidia released in their late igp/ION GPUs (do not confuse with the ION chipset).
Nvidia requested that patent in November 2007 and his application was finally approved, which is great news for Nvidia, but could be very bad news for companies like LucidLogix and AMD, which have similar technologies as VIRTU MVP , and Dynamic SG/Switchable Graphics PowerXpress respectively, which could be sued by Nvidia, claiming patent infringement.
interchangeable graphics technology is widely used in industry, so it remains unknown how it will affect the newly obtained patent from Nvidia.
