AT&T Mobility LLC must pay $166.3 million in damages for infringing Finesse Wireless LLC's patent rights with its 4G/LTE and 5G wireless networks, a jury in East Texas federal court said Friday.

The jury found that AT&T's networks, which use Nokia-made equipment in cell towers, infringe two patents owned by Finesse on reducing interference to wireless signals.

Nokia and AT&T said in a joint statement that they disagree with the ruling and are considering an appeal.

Finesse's senior attorney, Joe Grinstein of Susman Godfrey, said in a statement that the company is satisfied with the verdict.

Finesse, the patent-holding company of Francis Smith's inventor in Park City, Utah, sued AT&T in 2021 for patent infringement. Nokia, which designed and built the base stations used for AT&T's networks, intervened in the case later that year.

According to Finesse's lawsuit, AT&T's wireless networks incorporate its proprietary technology to reduce interference from other signals that can lead to dropped calls, poorer voice quality and slower data transmission.

AT&T and Nokia have denied the allegations. The jury on Friday rejected their argument that the patents were invalid.
