A U.S. district court jury ruled that mobile VPN software vendor NetMotion Wireless infringed on two patents held by competitor Padcom.

The patents at issue cover the core technology for Padcom's TotalRoam solution, which lets users continue to use a wireless data application while roaming across multiple, dissimilar active networks, said Richard Reed, Padcom's general counsel.

Padcom was granted the primary patent at issue in the case in July 2002, Reed said. The company filed the lawsuit against NetMotion in October 2003 and subsequently amended the plea to reflect the award of another patent. The court will decide damages associated with the verdict at an undetermined date, Reed said.
