Rambus fails at ITC
The US International Trade Commission (ITC) has decided against Rambus in a patent infringement case brought by Rambus against LSI Logic, ST Microelectronics, Nvidia, Broadcom, Freescale and MediaTek.
“We are evaluating our next steps in this matter, which may include a possible appeal to the Federal Circuit,’ says Thomas Lavelle, general counsel at Rambus.
Rambus had asked for an exclusion order barring the importation, sale for importation and sale after importation of products that infringe certain Rambus patents from the Dally and Barth patent families.
The Dally patents affected products which include PCI Express, certain Serial ATA, certain Serial Attached SCSI (SAS) and DisplayPort interfaces.
The Barth patents include products that use DDR, DDR2, DDR3, mobile DDR, LPDDR, LPDDR2, and GDDR3 memory controllers. Affected semiconductor products include graphics processors, media processors, communications processors, chip sets and other logic integrated circuits (ICs).
The ITC has upheld a court ruling that the patents are unenforceable because of prior art.
Since the investigation was instituted, Rambus has signed settlement and patent license agreements with Broadcom, Freescale, MediaTek and Nvidia.
