US court clears Qualcomm on Broadcom charges

A federal appeals court ruled that Qualcomm did not infringe a patent held by rival Broadcom involving technology that allows mobile phones to save power, a Dow Jones report said.

The US court also ruled that seven Qualcomm chips did not infringe a similar Broadcom patent, the Dow Jones report added.

The court, however, ordered further investigation on whether one Qualcomm chip infringed on Broadcom's technology.

The ruling did not address a related, highly publicised and crucial appeal by Qualcomm that is pending at the same court.

In that case, Qualcomm is appealing a ruling by the US International Trade Commission that could bar certain mobile phones from being imported into the US, the Dow Jones report further said.
