IP company sues AMD over patents

Filed under

Opti, a chip-oriented intellectual property company, said it has filed a lawsuit alleging that Advanced Micro Devices violated three patents with its Opteron processors and other products.

Opti, which is based in Mountain View, California, alleges in its patent infringement suit that the chipmaker infringed on patents related to "predictive snooping" technology.

Opti alleges that AMD infringed on its patents 5,710,906, 5,813,036 and 6,405,291. The technology is designed to shorten the delay of an inquire cycle when a PCI bus controller receives a data transfer request from a PCI bus master.
