Netlist prevails in patent reexamination appeal Netlist announced that the Patent Trial and Appeal Board of the United States Patent and Trademark Office issued a decision upholding the validity of all 60 claims in the reexamination of U.S. Pat. No. 7,532,537 brought by Inphi Corporation. In its decision on January 16, the PTAB dismissed every single validity challenge raised by Inphi and affirmed the Examiner's decision to allow the claims. These claims are directed to fundamental concepts of load reduction and rank multiplication which are integral to the design of LRDIMMs. 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. Netlist has steadily invested in and grown its IP portfolio, which now includes 41 issued patents and more than 29 U.S. and foreign pending patent applications in the areas of high performance memory and hybrid memory technologies.
