The jury awarded Broadcom $19.64 million in damages adter finding that Qualcomm's had infringed the patents.

The patents cover simultaneous use of a single transceiver on two networks, a chip architecture for performing video processing and technology that allows phones to use either fixed or variable bandwidth networks.

Broadcom said it would next seek a permanent injunction barring Qualcomm from using the three patents.

The verdict follows a 13-day trial in the long-running patent battle between the wireless chip rivals. The U.S. International Trade Commission is expected to announce a remedy by June 7 on its earlier finding that Qualcomm's 3G baseband chips infringed a Broadcom patent on power-saving technology.
