The U.S. Patent Trial and Appeal Board (PTAB) this week ruled in favor of Intel and invalidated one of VLSI's patents that is central to the $2.18 billion patent infringement verdict from 2021, reports Reuters. The significant ruling comes on the heels of the invalidation of another VLSI patent that was a part of the same verdict back in May.
Back in 2021, a District Judge in Waco, Texas, sided with VLSI and awarded a $2.18 billion patent infringement payment: $1.5 billion for a SigmaTel-developed frequency management patent ('759'), and $675 million for a Freescale-originated memory voltage reduction method patent ('373'). Intel appealed the decision, but failed to overturn it in August, 2021, so Intel turned to the PTAB to invalidate both patents.
