The Taiwan developer of integrated microcircuits richtek technology gave action to the USA commission on the international trade (ITC) about the disturbance of patent rights from the side of AMD and still four well-known companies: Sapphire technology, Diamond multimedia, XFX and uPI semiconductor. Plaintiff also asserts that the accused companies used its commercial secret in an unbecoming manner.
Concrete subject of debate was not communicated, but in the sphere of richtek technology activity it is possible to assume that we deal with certain technologies of voltage control , used in video card. Sapphire, Diamond and XFX sympathize with overclock in one or another manner; therefore, on their production are provided mechanisms of voltages increase on the core and memory. Possibly, some of these solutions were patented by Richtek .
ITC already accepted action and began its own investigation.
