United States Federal Circuit

Where a single chip contained both a graphics controller and dynamic random access memory (DRAM), summary judgment of noninfringement as to the patent directed towards the redesigned logic gate that decouples the voltage source from that of the substrate, affirmed; however, the judgment of noninfringement of the patent directed towards the reverse-biased n-well invention, vacated and remanded for further proceedings on the proper construction of "power supply" and whether the accused devices infringe under the proper interpretation of the claims.
