An International Trade Commission judge recommended an import ban on some iPhones, after finding Apple Inc. violated one of Qualcomm's patents.

Administrative Law Judge MaryJoan McNamara ruled on March 26 that Apple had violated one of Qualcomm's hardware patents, according to Bloomberg. She is recommending a limited exclusion order and a cease and desist order, according to a notice released Tuesday afternoon.

Qualcomm is expecting another key decision from the ITC later today. The full commission is expected to decide this afternoon whether Apple violated Qualcomm’s intellectual property for power-saving technology, with the potential to enforce an import ban on infringing products

In September, Administrative Law Judge Thomas Pender ruled that Apple had violated one of Qualcomm’s patents, but recommended against an import ban due to public interest.

Apple and Qualcomm have been locked in an ongoing legal battle for the last two years. Qualcomm has accused Apple with violating its patents and breach of contract. Apple, for its part, has accused Qualcomm of using its market power to overcharge phone makers for licensing fees.

An import ban would put much more pressure on Apple than the $31 million in damages Qualcomm was awarded after a San Diego jury ruled in its favor on March 15. But it’s not the final case in the ongoing legal battle between the two technology giants.

Apple is bringing an antitrust case to trial against Qualcomm in April in the U.S. District Court for the Southern District of California. The companies are also awaiting a final decision from District Judge Lucy Koh after the Federal Trade Commission concluded its antitrust trial against Qualcomm last month.
