Qualcomm says it has scored an important victory in its long-running global patent battle with Apple over patent rights. According to Qualcomm, a Chinese court ruled that several recent iPhone models infringe multiple Qualcomm software patents and has ordered a nationwide ban on iPhone sales. Apple says it has already appealed the ruling.

The ruling occurred on November 30, but Qualcomm announced the ruling today.

Apple has downplayed the ruling’s significance, telling media outlets that the ban has not yet taken effect and that it only applies to older versions of iOS software, not to the current version, iOS 12. The ruling also only applies to older iPhone models—including the iPhone 8 and iPhone X—but not to the iPhone XS and XR.
