The runaway train wreck of memory lawsuits started by Rambus may finally be coming to an end . In a U.S. District Court, Judge Sue L. Robinson has ruled that Rambus’s patent suit against Micron Technologies is “unenforceable”. In her ruling she specifically cites “spoliation”, which is defined as the “destruction or alteration of evidence”. Essentially Rambus has been accused of failing to preserve documents that could be admitted as evidence. This news comes as an incredible relief to Micron Technologies, the single largest U.S. manufacturer of memory chips. Though this ruling is specific to the Micron case, if it holds up in the inevitable appeal, several other companies facing Rambus lawsuits such as Nvidia , Samsung, Hitachi, and Hynix may also be spared.
Judge Robinson also voiced her disapproval for Rambus’s aggressive tactics by using lawsuits against competitors. In her ruling she quotes a specific email from September 29 th 1999 whereby the author declares the “need to sue a dram company to set an example”. The email also specifically states that they should attempt to publicize the patents and lawsuits to “put all dram/controller companies that use sdram/ddr….on notice.”
Rambus has publically denounced the ruling and according to senior vice president Tom Lavelle, “"We respectfully, but strongly, disagree with this opinion, and at the appropriate juncture plan to appeal." "This opinion is highly inconsistent with the findings of the Court in the Northern District of California which looked at the same conduct and found there was nothing improper with our document retention practices. We are confident in the strength of our position and will continue to vigorously pursue fair compensation for the use of our patented inventions."
Is Rambus just a patent trolling?
