Qualcomm has launched another lawsuit against Apple, accusing the iPhone maker of sharing proprietary code with Intel, according to a report from Bloomberg.

The lawsuit claims that Apple breached contract with Qualcomm in regard to software that’s required to allow mobile chips to interact with the rest of a phone. It’s the latest in a series of lawsuits between the two companies, which kicked off back in January when Apple sued Qualcomm and accused the chip maker of overcharging for use of patents.

Currently, Apple manufactures its phones with chips from both Qualcomm and Intel, although a recent report from The Wall Street Journal indicated that the company could be dropping Qualcomm entirely as a result of the ongoing squabbles between the two companies.
