SanDisk Facing Court Injunction Banning Sale of UlltraDIMMs In U.S. Market

SanDisk Corporation, a world-leading producer of flash storage devices, has been delivered a preliminary injunction against the continued sale of their current version of UlltraDIMM memory channel storage devices in the United States. These UlltraDIMMs were produced in partnership with Diablo Technologies, who provides the memory controller ICs utilized in their production. The issue at heart is the fact that Diablo is using memory interface technology that had been patented by Netlist, another producer of memory modules, without Netlist’s approval or licensing.

SD-ULLtraDIMM-SSD-front-and-backThe preliminary injunction was ordered by Judge Yvonne Gonzalez Rogers of the U.S. District Court for the Northern District of California. The judge also moved up the trial date by some four months to March 9, 2015, signaling that she felt there was a strong chance that Netlist would prevail at trial, barring a settlement prior to the court date. The judge also rejected SanDisk’s motion that it should be allowed to sell its existing inventory, finding that since SanDisk has a long-term contract with Diablo for the production of UlltraDIMMs, that it was proper that they be included under the injuction. Legal observers indicate that the issuing of such a preliminary injunction is liable to accelerate SanDisk’s desire to negotiate an out-of-court settlement.

Netlist subsequently discovered that Diablo was using the same technology in its own products, and thus had harmed Netlist’s ability to sell its own NVvault and HyperVault products. Diablo’s stated defense to date is that it was entitled to use the information that was supplied by Netlist.

The court also identified IBM’s eXFlash memory modules as infringing, and hence also banned. OEM’s such as Huawei, Supermicro and Lenovo had plans to offer ULLtraDIMM equivalents, and these plans are now on hold pending resolution of the dispute.

Hong, CEO of Netlist, “The ruling serves as a major step towards establishing the rightful ownership of the intellectual property contained in the ULLtraDIMM, and clears the path for Netlist products based on our proprietary memory interface technology. We look forward to the opportunity to present all of the evidence to a jury, particularly given the court’s assessment of our likelihood of prevailing.”
