Intel Triumphs in London Patent Dispute Against R2 Semiconductor

Intel won a crucial patent dispute against R2 Semiconductor in London. The case, which revolves around patents for fully integrated voltage regulators in microprocessors, saw the High Court invalidate R2's patent. The decision contrasts with a previous German ruling in favor of R2.

Intel claimed victory in the London leg of a worldwide patent dispute with U.S. competitor R2 Semiconductor on Wednesday, which sought to block the sale of certain Intel chips.

R2 Semiconductor filed a lawsuit against Intel at London's High Court in 2022, alleging that Intel's chips and processors with fully integrated voltage regulators violated its patent. Intel responded by contesting the validity of R2's patent, leading to a High Court ruling in Intel's favor.

According to Judge Richard Hacon's written ruling, R2's patent lacks an 'inventive step,' rendering it invalid. He noted that Intel would have been in violation if the patent had been upheld. Neither Intel nor R2 has commented on the decision yet.
