The battle between Apple and Qualcomm and Apple is turning downright nasty.

Hot on the heels of Apple’s counter-lawsuit, Qualcomm has filed three new patent infringement claims against the iPhone-maker. It is also seeking a ban on the import of all AT&T and T-Mobile iPhone X and iPhone 8 units in the US which could cause major headaches for Apple.

Qualcomm said today that its three new claims show that Apple is infringing on 16 more of its patents on the latest iPhones. The complaints come after Apple filed its own patent-infringement lawsuit against Qualcomm on Wednesday for using tech in its Snapdragon mobile phone chips that belong to Apple.

The two companies have been fighting throughout most of 2017. Problems between the two companies stem from Apple’s refusal to pay some patent royalties to Qualcomm because the company thinks it is not being charged fairly.

In its filing with the U.S. International Trade Commission, Qualcomm is seeking to ban the import of all Apple iPhones that use Intel’s LTE modems. All three of the new patent cases were filed in U.S. District Court for the Southern District of California in San Diego.

At this point, it’s starting to get hard to keep track of just how many lawsuits have been filed between the two companies. It’s unlikely that Qualcomm’s filing will impact the iPhone X sales in the immediate future. However, the lawsuits will keep Apple’s lawyers busy for the next few years.
