A new set of legal filings from telecommunications equipment maker Qualcomm in its ongoing court battle with Apple will seek to ban the sale of iPhone X offered by multiple carriers in the United States.
According to the three new lawsuits filed by the company this week, Qualcomm has accused Apple of infringing on 16 separate patents. The lawsuit alleges Apple used the technology in the iPhone 7, 8 and X, as well as multiple iPhone Plus models.
The patents in question primarily relate to technology used to improve battery life, but spans across multiple areas of smartphone technology that is allegedly utilized within the iPhone line. Qualcomm also claims that Apple is using patented technology in the iPhone’s Portrait Mode photo effect.
Qualcomm also alleges the multitasking interface introduced with the iPhone X shares many similarities with the interface that WebOS used to use. The operating system is effectively defunct for smartphones but is still used in smart devices. While the technology was originally developed by Palm, Qualcomm purchased the company’s patent portfolio in 2014.
“All of these Palm inventions — owned by Qualcomm — have vastly improved the functionality of mobile devices and the user experience, and all of them are widely found in Apple products without license or permission,” Qualcomm argued in its lawsuit.
Qualcomm, a California-based manufacturer perhaps best known for its line of processors that are widely used in smartphones, is seeking unspecified payments from Apple for its alleged infringement on the patents.
Qualcomm has also filed a claim with the United States International Trade Commission in which the company asked for imports of the iPhone X that uses modems produced by Intel to be banned from sale in the U.S.
AT&T and T-Mobile sell models of the latest iPhone that use the Intel model. Carriers that sell the iPhone X with a modem provided by Qualcomm—available through Verizon, Sprint and sold as an unlocked device—would still be available.
The call for a ban on the iPhone X is the second time this year Qualcomm has pushed for Apple’s signature device to be barred from being sold in the U.S. The company asked for a similar restriction on the iPhone 7 in July and updated its request to include the iPhone X, as it was not available at the time of the original filing.
Qualcomm’s recent filing came shortly after Apple filed its own patent infringement lawsuit against Qualcomm. In a filing made Wednesday, Apple claimed Qualcomm’s Snapdragon mobile processing chips that are found in many Android devices infringe on Apple patents. In the same filing, Apple referred to Qualcomm’s behavior as that of a “common patent troll.”
The ongoing battle between Apple and Qualcomm started earlier this year after the Federal Trade Commission accused Qualcomm of anti-competitive behavior , which prompted Apple to file a lawsuitclaiming Qualcomm had been overcharging for use of its patents.
