Netlist Prevails in Reexamination of LRDIMM Patent at USPTO

IRVINE, CA, Aug 25, 2014 (Marketwired via COMTEX) -- Netlist, Inc. NLST, +14.29% a leading provider of high performance memory solutions for the cloud computing and storage markets, announced today that the Patent Trial and Appeal Board ("PTAB") of the United States Patent and Trademark Office ("USPTO") issued a final decision in the reexamination of U.S. Pat. No. 7,532,537 ("'537 Patent") denying Inphi Corporation's request for a rehearing. The '537 reexamination appeal in the USPTO is now closed.

With this action, the PTAB reaffirmed its earlier decision upholding the validity of all 60 claims in the '537 patent reexamination, dismissing every single validity challenge raised by Inphi. These claims are directed to fundamental concepts of load reduction and rank multiplication which are integral to the design of LRDIMMs at DDR3 and DDR4. Inphi's only opportunity to challenge the PTAB's final decision is an appeal to the U.S. Court of Appeals for the Federal Circuit, which it must file by mid-October 2014. The '537 Patent is also the subject of litigation between Netlist and Inphi in the Central District of California, which has been stayed pending the outcome of the reexamination, including any subsequent appeals.

"This significant victory in the USPTO represents a culmination of over four years of focused effort and validates our position as the innovation leader in high performance server memory," said C.K.

We are confident of prevailing at the Federal Circuit should Inphi decide to challenge the PTAB's ruling. We expect to achieve similar success in our other ongoing reexaminations and continue to aggressively pursue monetization...
