Action in the early part of the week saw a jury seated and opening arguments begin in the trial, taking place in Virginia.
Rambus accuses Infineon of infringing on its SDRAM (synchronous dynamic RAM) patents. Legal action was sparked after Infineon refused to pay Rambus licensing fees for the technology. Rambus' patents were previously available in the DRAM patent pool and were freely available until the company decided to start charging licensing fees. After demanding licensing fees, Toshiba, Mitsubishi Electric, Hitachi, NEC and Samsung Electronics all signed deals with Rambus. Three chipmakers -- Infineon, Micron Technology and Hynix Semiconductor -- refused and are now facing suits.
The trial is expected to last about four weeks and could bring Rambus a substantial amount of money if the company is victorious.
