Apple Inc. and Qualcomm Inc. each notched victories from a U.S. trade body in their yearslong feud over patent licensing, hardening the divide between them ahead of a federal trial slated to begin next month.

Apple netted the more significant victory Tuesday, with a ruling by members of the U.S. International Trade Commission that the iPhone maker didn’t violate a patent held by its former chip supplier. That ruling effectively overturned an ITC administrative judge’s finding in September that Apple had violated a Qualcomm patent related to power efficiency in mobile phones.

A less-definitive decision came just hours earlier from another ITC administrative judge in a separate patent claim by Qualcomm. In that case, the judge issued an initial finding against Apple and recommended a limited ban on iPhone imports. That recommendation is still subject to review by the ITC—a six-member group that currently has one open slot—and potentially by the Trump administration.

Qualcomm said it would ask the ITC to reconsider the commissioners’ ruling because it was inconsistent with a recent jury finding that Apple infringed on the same patent at issue in that case. Qualcomm said the ITC judge’s interim finding affirmed the value of Qualcomm’s technologies.

An Apple spokesman said the ITC’s finding that Qualcomm’s patent claim was invalid was an important step to preserving fair competition. He added, “We look forward to detailing the many ways they’re harming consumers and stifling innovation when we present our case in San Diego next month.”
