A Marshall jury concluded Friday that Barnes & Noble Inc. didn’t infringe a patent owned by Alexsam Inc., a patent holding company that sued B&N and six other major retailers over their use of gift card technology.

After a one-week trial before U.S. District Judge Michael Schneider and five hours of deliberation, the jury returned a unanimous 7-0 verdict of non-infringement. Alexsam was seeking $72 million in damages and a running royalty from Barnes & Noble, which was represented by Alan Fisch of Fisch Hoffman Sigler.
