Intel claims that the described technology will not work with its CPU.
Intel will have pay nearly $1 billion to stop patent infringement. We are also talking about a patent trolling company.
Texas’s court ruled in favor VLSI. This dormant company is owned by Fortress Investment Group, a private equity firm. Intel was ordered by a Texas court to pay $949 Million in fines for infringing an almost 20-year-old patent.
VLSI acquired the patent from NXP Semiconductors. According to the plaintiff, it causes “millions and million violations per second” in Intel processors.
US7247552B2 describes how to troubleshoot defects caused by voltage applied on the pads. The patent technology adds dummy metal lines between interconnect layers, increasing the metal’s density.
VLSI asserts that Intel used the technology for years, right up to the Cascade Lake generation of 2019. Intel claims it did not use the development and that the Cascade Lake and Skylake generations mentioned in the lawsuit are made using Intel’s proprietary technology. Intel also claims that the patent technology will not work in modern CPUs.
It is important to note that this is not VLSI’s first or last trial. VLSI won an almost $2.2 billion case in March. Intel has however filed an appeal. VLSI lost a patent case against Intel in April. There are two additional lawsuits pending.
