R2 Semiconductor

R2 Semiconductor is a company specializing in high-frequency semiconductor technology for power management. The company's core focus is on integrated voltage regulation technology, which is critical for various electronic devices. R2's Fast Power Technology claims to offer a tenfold improvement in switching frequency, bandwidth, and size compared to conventional power management solutions. This technology is particularly relevant for mobile phones, laptops, and server-processor chips.

R2 Semiconductor holds a European patent (EP three 376 653 B1) that covers voltage-regulation technology, specifically related to overvoltage protection for switching converters in integrated circuit units. The company asserts that its patented technology is utilized in Intel's "fully integrated voltage regulator" found in several generations of Intel processors, including Core and Xeon chips.

The company has been involved in legal disputes with Intel over patent infringement in multiple European countries. In February 2024, the Düsseldorf Regional Court in Germany ruled in favor of R2 Semiconductor, finding that certain Intel central processing units (CPUs) embedded in electronic devices infringed on R2's patent. This ruling led to an injunction against the sale of some Intel processors in Germany. The patent extends throughout Europe until 2030, potentially allowing R2 to enforce it in 39 European Patent Convention member states.
