Lowenstein & Weatherwax successfully defended its complete IPR trial victory on behalf of its client VLSI Technology LLC before the United States Court of Appeals for the Federal Circuit. On April 6, 2021, the Federal Circuit affirmed the Patent Trial & Appeals Board’s Final Written Decision finding that claims 1-5, 9 and 12 of U.S. Patent No. 8,268,672 were not proven by the petitioner, Intel Corporation, to be unpatentable. Every single claim at issue in the IPR trial was successfully defended in the trial and the Federal Circuit’s affirmance issued less than 24 hours after oral argument was heard in the Court on April 5.

L&W founding partner Nathan Lowenstein presented the argument for VLSI both at trial before the Board and before the Federal Circuit. Lowenstein said, “We are thrilled to secure this victory on behalf of our client and are grateful for the opportunity to defend VLSI both before the PTAB and the Federal Circuit.” This win was Lowenstein’s second Federal Circuit win on behalf of VLSI affirming a complete IPR trial win below.  These Federal Circuit victories build upon Lowenstein’s prior success as Lowenstein also was able to obtain 13 denials of institution in 13 other IPRs brought by Intel and successfully defended VLSI in four of five trials.  “I am very thankful for the invaluable contributions from my colleagues, including Ken Weatherwax, Bridget Smith, Greg Smith, Flavio Rose, Edward Hsieh, and Jason Linger,” Lowenstein added.
