The International Trade Commission’s ban on imports of cell phones made with chips by Qualcomm (NSDQ: QCOM), a court ruled Tuesday. AP reported that the ITC imposed the ban in June 2007 because it said some of the Qualcomm chips infringed on patent owned by Broadcom, but the court found that the ITC lacked the authority to ban Motorola (NYSE: MOT) and Samsung phones because their phones included Qualcomm chips. It sent the case back to the commission. The findings is just the latest step in a long-standing battle between Qualcomm and Broadcom. Both companies issued statements. Qualcomm’s Don Rosenberg said: “Qualcomm is very pleased with the Court’s opinion. In effect, the Court has disapproved Broadcom’s tactic of attacking the wireless industry, including handset manufacturers and wireless operators, without providing them with the opportunity to defend themselves in the action.” Broadcom spokesman Bill Blanning said: “We look forward to addressing this issue upon remand to the ITC. We will continue to pursue other avenues for enforcement against infringement of our intellectual property by Qualcomm.”
