British semiconductor company Arm Ltd. announced on Wednesday that it is suing U.S. tech company Qualcomm Inc. for the breaching of licensing agreements and for trademark infringement.

Arm, which designs processors, claimed that the contract was breached after Qualcomm acquired Nuvia Inc., a deal completed in May 2021 for $1.4 billion. Arm creates and sells its chip designs to clients and Nuvia has some past designs.

Arm, which is owned by SoftBank Group Corp., wants Qualcomm to "destroy any Arm-based technology developed under the licenses" — but that Nuvia and Qualcomm continued to leverage the Arm tech."

"Further, Qualcomm's conduct indicates that it has already and further intends to use Arm's trademarks to advertise and sell the resulting products in the United States, even though those products are unlicensed," according to court documents.

Qualcomm denied that it breached the contract.

"Arm's complaint ignores the fact that Qualcomm has broad, well-established license rights covering its custom-designed CPU's, and we are confident those rights will be affirmed," Ann Chaplin, Qualcomm's general counsel, said in a statement.
