Netlist Adds Two Patents to ULLtraDIMM Litigation

Netlist, Inc. has filed motions to add two additional patents to the lawsuits against the recently announced ULLtraDIMM memory module from Diablo Technologies, Inc., and Smart Storage Systems, Inc.

The lawsuits are pending before Judge Gonzalez Rogers in the United States District Court for the Northern District of California in Oakland, CA.

The two newly added patents (U.S. Patent Nos. 7,881,150 and 8,081,536) are generally related to load reduction, a critical feature in low latency memory modules. These patents are part of the same family as U.S. Patent No. 7,532,537, which has been upheld by the Patent Trial and Appeal Board (PTAB) following a three-year reexamination. The ‘150 and ‘536 patents were examined and issued in view of prior art cited in the reexamination.

Netlist has now asserted a total of seven patents against the ULLtraDIMM, in addition to trade secret theft, trademark infringement and other claims.

“We have spent years developing our industry-leading technology, and are encouraged by the progress we’ve made defending our intellectual property in these lawsuits,” said Netlist president and CEO, C.K. Hong.

As reported in its 8-K last December, the company received a whistleblower letter describing in detail how Diablo “stole Netlist’s detailed architecture and design” of its flagship product, HyperCloud, to create the ULLtraDIMM.

“We will continue to vigorously defend our IP, uncovering any and all theft of our technology and infringement of our patents, and will not allow others to profit from this unlawful activity.”

Netlist has invested in and grown its IP portfolio, which now includes 41 issued patents and more than 29 US and foreign pending patent applications in the areas of high performance memory and hybrid memory technologies.
