The U.S. Supreme Court put sharp new limits on where patent-infringement lawsuits can be filed, undercutting patent owners’ ability to channel cases to favorable courts.

The justices on Monday unanimously ruled in favor of TC Heartland LLC, an Indiana-based maker of water flavorings that said a Kraft Heinz Co. unit shouldn’t be allowed to sue it in Delaware. The high court said patent suits should be filed in the state where the defendant is incorporated.
