A jury ruled Monday that T-Mobile USA, Inc. did not infringe on two patents from Prism Technologies Group that cover a method for controlling access to protected computer resources.
The decision is the third in a series of five lawsuits filed against U.S. carriers in 2012 for infringement of the database and networking technology patents.
In November 2014, AT&T began a jury trial against Prism, but settled out of court before a verdict could be reached. Sprint also went to court against Prism, but lost in June 2015 when a jury found the carrier’s Simply Everything and Everything Data plans were in violation of the patents and ordered Sprint to pay $30 million in damages.
Following the Sprint outcome, Prism President said the company appreciated the jury’s “hard work and their attention to the evidence.”
The two remaining suits are against United States Cellular Corporation and Cellco Partnership d/b/a Verizon Wireless, which are scheduled to go to trial on November 9, 2015 and April 4, 2016, respectively. In those suits, Prism said it will seek royalty damages based on the outcome of the Sprint suit.
The patents in question expire in June 2017.
