This lawsuit was filed back in 2009. The original complaint was made by Spring Design, and they claimed that Borders had copied some of SD's intellectual property.
The settlement doesn't really make much sense, if you ask me. The only part of the settlement that has been released is that B&N get to use all of Spring Design's patents. Also, the lawsuit was dismissed with prejudice, which means it can't be retried.
