The U.S. International Trade Commission is reversing an administrative law judge's findings that Apple's iPhones infringed on technology owned by Qualcomm.

The decision invalidating Qualcomm's patent claim handed Apple a victory late Tuesday in Washington. It came a few hours after Apple suffered a setback in another ITC case brought by Qualcomm that could still result in a U.S. import ban on some iPhones.

It's all part of a messy battle between Apple and Qualcomm over which company owns the rights to some of the technology underlying key features in the iPhone.

In the latest development, the trade commission tossed aside a decision reached last September on one of Qualcomm's patent claims.

The commission must still review Tuesday's earlier decision, which found that an iPhone feature violated a different Qualcomm patent.

A trade court judge will recommend banning some iPhones from being imported into the U.S. after concluding Apple's best-selling device infringed on technology owned by mobile chip maker Qualcomm.

The U.S. International Trade Commission decision is the latest twist in a bitter legal dispute between Qualcomm and Apple over the rights to some of the technology that connects iPhones to the internet.

It's unclear if the recommended ban will be imposed or even which iPhone models would be affected. McNamara's recommendation still must be weighed by the full trade commission.

Qualcomm applauded McNamara's findings. Apple didn't immediately respond to a request for comment.

A similar decision was reached by a trade commission judge last September in another patent infringement case that Qualcomm filed against Apple. The full commission is expected issue its ruling on that judge's initial findings later Tuesday.

The legal battle between Qualcomm and Apple broke out more than two years ago after the U.S. Federal Trade Commission sued Qualcomm for allegedly using its portfolio of mobile technology patents to gouge smartphone makers and stifle competition in the chip market. A federal court judge in San Jose, California, is still mulling a decision in that case, two months after presiding over a trial.

Shortly after the FTC filed its case in 2017, Apple pounced with its own lawsuit accusing Qualcomm of trying to wring licensing fees for technology that it didn't really invent.

Apple subsequently stopped paying royalties to Qualcomm, further poisoning the two companies' relationship.

Qualcomm prevailed in another round of skirmishing when a federal court jury in San Diego decided Apple should pay $31 million in damages for making several different types of iPhones that violated Qualcomm patents. The bout is scheduled to resume April 15 at yet another federal court trial in San Diego.
