ITC says ST Micro, others didn't violate Rambus patents

ITC judge rules in favor of Rambus accused

Rambus has hit a wall in its patent infringement case against ST Micro and other respondents. Following its success in forcing licensing deals with Broadcom, Freescale and NVIDIA, an Administrative Law Judge at the ITC has ruled that ST Micro has not infringed on patents owned by Rambus and is free to continue importing memory modules into the US. Rambus is currently considering options, which includes requesting a full Commission review of the ALJs Initial Determination.

'We have yet to receive the decision, but are disappointed with the initial determination of no violation, said Thomas Lavelle, senior vice president and general counsel at Rambus. 'We believe in the strength of our portfolio and remain committed to protecting our patented inventions from unlicensed use,' he added.

The patent claims Rambus leveled at ST Micro included technologies used in PCI Express, Serial ATA, Serial Attached SCSI and DisplayPort. Additional patent claims were for DDR, DDR2, DDR3 and mobile DDR, LPDDR, LPDDR2 and GDDR3 memory controllers. This is the second major setback Rambus has suffered in recent times. In January the USPTO ruled three core Rambus patents invalid. However, the same ALJ that ruled against Rambus in its case against ST Micro has previously found that NVIDIA had violated certain Rambus' patents resulting in NVIDIA agreeing to a licensing deal.
