The semiconductor industry appears to generate a specific type of legal dispute more frequently than most; these disputes are slow, costly, technically complex, and nearly impossible to settle amicably. The battle between Intel and VLSI Technology has come to represent that category in some ways. As of this week, a federal appeals court overturned a lower court’s conclusion of noninfringement and remanded the case to a jury in a California lawsuit that was filed in 2017. That’s a challenging development for Intel, a company that had every reason to believe this particular chapter was closed.
US Patent No. 8,566,836, which was first submitted by Freescale Semiconductor in 2009, is the patent at the heart of the most recent decision. The name Freescale, a Texas-based chipmaker that separated from Motorola and was eventually acquired by NXP Semiconductors, a Dutch company, is no longer in the news. However, its outdated intellectual property has proven to have a lengthy and lucrative afterlife. After acquiring a portfolio of patents from Freescale and NXP, VLSI Technology, a patent holding company under Fortress Investment Group, has spent almost ten years claiming that Intel’s contemporary processors violate the techniques covered by those patents. The ‘836 patent focuses on how a multi-core processor assigns tasks among its cores by measuring its own maximum frequency. It sounds ethereal. It doesn’t seem to be in the context of how Intel chips actually operate.

Anyone’s patience would be tested by the way the case has progressed through the legal system. A Texas jury awarded VLSI $2.18 billion in 2021, a decision that garnered media attention and momentarily appeared to be a turning point in the conflict. It was later overturned by the Federal Circuit. A different Texas jury returned a $948.8 million verdict on various patents in 2022. Intel also contested that. In the meantime, the ‘836 patent claim was being handled by Judge Beth Freeman in the Northern District of California. In 2024, she found that Intel’s chips did not violate the patent, a summary judgment that Intel naturally applauded. A three-judge Federal Circuit panel has now overturned that decision, concluding that a jury would be a better judge and that the case was not appropriate for summary judgment.
Although it might not be immediately apparent, there is a catch that is significant. Judge Freeman’s decision to exclude Dr. Ryan Sullivan, VLSI’s damages expert, on the grounds that he did not sufficiently disclose his methodology and the company’s damages claims was upheld by the appeals court. That is a significant limitation. Although Sullivan’s exclusion limits their options for damages and may limit their financial exposure, VLSI is still able to bring another expert to the retrial. Additionally, Intel was able to prove in earlier proceedings that the measurement-related aspects of the alleged infringement mostly took place outside of the United States during the testing and packaging stages rather than in American manufacturing facilities. If the jury finds infringement, that geographic argument may further restrict how damages are ultimately determined.
As this has developed over almost ten years, it seems that the case is now as much a structural and financial narrative as it is a legal one. VLSI is not a conventional technology business. It doesn’t produce anything. Its primary purpose is to hold and enforce patents, a business strategy that provokes strong reactions in the tech sector. VLSI has been referred to as a patent troll by critics, including some Intel supporters in online forums. A patent troll is a business that purchases intellectual property not to use it but to demand licensing fees or jury verdicts from businesses that actually produce goods. VLSI supporters would retort that the original inventors at Freescale and NXP produced genuine innovations that Intel purportedly profited from without payment, and that valid patents should be enforced regardless of who owns them.
Another level of complexity is introduced by VLSI’s ownership structure. SoftBank owned the majority of Fortress Investment Group, which is in charge of VLSI, until 2024, when a group headed by Mubadala Investment Company in Abu Dhabi purchased a controlling stake. This indicates that the organization pursuing a multibillion-dollar lawsuit against an American chip manufacturer is now heavily supported by sovereign wealth from the United Arab Emirates. The merits of the patent dispute may be completely unaffected by the context. However, it’s also the kind of information that frequently comes up in public debates concerning the effectiveness of patent enforcement in the semiconductor industry.
For its part, Intel is not in the best position to be engaged in costly legal disputes at this time. In 2025, the business was not profitable. Following the release of its most recent earnings, its shares fell 13%. It is placing a significant wager on artificial intelligence and its next-generation processors to end a protracted period of strategic and financial hardship, and every dollar spent on litigation is a dollar lost on that recovery. In order to circumvent appeals restrictions, the company has also attempted an uncommon procedural move in this case: joining third-party challenges to VLSI’s patents filed by other businesses, thereby attaching itself to complaints it did not originate. It’s an innovative legal strategy that demonstrates how seriously Intel takes the threat.
A jury trial on the ‘836 patent will now take place in the California district court in the case officially named VLSI Technology LLC v. Intel Corp. There are still many unanswered questions, such as how long that process will take, what damages VLSI can prove with a new expert, and whether Intel’s claims of geographic infringement will hold up. Whether this ends in a settlement, another significant verdict, or something in between is still up in the air. It is evident that a lawsuit that was started nine years ago is far from over, and Intel, which is already going through one of the most difficult periods in its corporate history, will have to deal with it for some time to come.
