Patent law is often confusing, especially when the alleged patent infringement is from none other than Intel. In just one of many twists in a story spanning almost a decade, the US appeals court has restarted proceedings for VLSI to take Intel back to court, continuing a $3 billion feud.
As reported by Reuters, the decision was given on April 14 in California. This decision is not inherently proof of wrongdoing and is not a judgment from the courts. It simply suggests that Intel will once again be fighting its case against VLSI in the future.
Effectively, VLSI owns many patents for techniques for handling speed, power, and architecture in processors. The company has alleged since 2017 that these are infringed upon in Intel's modern processors. These patents are ones that VLSI managed to get its hands on from the likes of Dutch chipmaking company NXP Semiconductors and Freescale Semiconductors.
