CALIFORNIAN company Acacia Research Corp., said its subsidiary, Computer Cache Coherency Corporation, has added chip-makers Intel and AMD to the list of companies it wants to sue for infringing its patents.

The company announced a suit against VIA back in December 2004 and has now ratcheted up is legal maneuverings to include the big two.

It says this trio used its technology in their core-logic chipsets, in a market it says that was worth $3billion in 2003.

In a statement it said memory cache coherency technology allows peripheral devices to communicate with system memory. It claims the technology was used by Intel, AMD and VIA in desktop notebook and server systems so now it is seeking recompense. µ
