I should add that the abandoned patent application is a continuation-in-part of two issued patents, if folks are curious: 8,433,617 and 8,346,624, both of which issued before the bar for software patents was raised (and blurred, to mix metaphors) in 2014 by the Supreme Court in Alice v. CLS Bank. Software patents issued before that case tend to not fare well under the current case law and are often thrown out in the first months of a suit (with a few exceptions in certain fora).
