In applying the U.S. Supreme Court’s much-discussed 2014 patent decision in Alice v. CLS Bank International, a Delaware federal judge has found patents for computer technology that helps airlines upsell seat offerings to passengers were directed at an abstract idea that could not be patented.

In Tenon & Groove v. Plusgrade, U.S. District Judge Gregory M. Sleet of the District of Delaware adopted a magistrate judge’s report and recommendation that Plusgrade’s motion for summary judgment be granted given plaintiffs Tenon & Groove and Optiontown’s patents were invalid.
