Chip firm Arm is cancelling an architectural license agreement that allows Qualcomm to use its intellectual property to design chips, a person familiar with the matter said, amid an ongoing legal battle between the two companies.

It's the former that Qualcomm has done with Snapdragon X, so the licence cancellation would apply to custom CPU designs, but not to other Qualcomm chips based on Arm CPU core designs. In other words, the cancellation wouldn't mean that Qualcomm couldn't produce any Arm chips at all, just Arm chips with its own in-house CPU core designs.

The chip technology company Arm has given Qualcomm 60 days notice, according to Bloomberg. Arm has reportedly canceled a license granted to Qualcomm to design chips based on its chip technology, according to a Bloomberg report on Tuesday.
