A Colorado federal judge on Thursday threw out a 2012 lawsuit brought by Teashot LLC against Starbucks Corp, Green Mountain Coffee Roasters Inc. and Green Mountain unit Keurig Inc. over its patented system for producting single-serving tea extracts with coffee makers.

U.S. District Judge William J. Martinez sided with the defendants in a ruling granting summary judgment. He zeroed in on the material of the lid used on the defendants’ single-serve drink packs and how such material interacted with water.
