A jury in a U.S. District Court in Delaware yesterday handed down a split verdict in Intellectual Ventures patent infringement lawsuit against Motorola Mobility, finding that the mobile phone company infringed one patent and not another.

The case Intellectual Ventures I LLC et al v. Motorola Mobility LLC was filed October 6, 2011 and originally involved six patents. The patents at issue in yesterday’s verdict were the U.S. Patent No. 7,810,144 patent for file transfer system for direct transfer between computers and the 7,409,450 patent for allocating wireless bandwith.

The jury found that Motorola Mobility infringed the ‘144 patent but not the ‘450 patent.

Bellevue, Washington-based Intellectual Ventures has a portfolio of some 35,000 patents, 3,000 of which were developed in house. The privately held firm founded by former Microsoft chief technology officer Nathan Myhrvold, Edward Jung, Peter Detkin and Greg Gorder, has spent some $400 million on patents and earned some $2 billion in licensing.

Intellectual Ventures said the two patents at issue in the verdict were software patents. Damages related to multimedia text messaging will be determined in a later trial.

The remaining patent in Intellectual Ventures case, related to Motorola hardware, will go to trial today, before another jury in the U.S. District Court for the District of Delaware.

“We are encouraged by today’s verdict and thank the jury for their hard work and careful considerations of these important issues,” said Melissa Finocchio, Intellectual Venture's chief litigation counsel. “As we look ahead to the next trial, we remain committed to defending inventor rights and protecting the interests of our investors and customers.”

In 2013, Intellectual Ventures filed a second action for infringement against Motorola in the U.S. District Court for the Southern District of Florida. The date of this trial has not yet been scheduled, due to a stay in the proceedings.
