U.S. top court tightens patent suit rules in blow to 'patent trolls'

The U.S. Supreme Court on Monday tightened rules for where patent lawsuits can be filed in a decision that may make it harder for so-called patent "trolls" to launch sometimes dodgy patent cases in friendly courts, a major irritant for high-tech giants like Apple and Alphabet Inc's Google.

The justices sided 8-0 with beverage flavoring company TC Heartland LLC in its legal battle with food and beverage company Kraft Heinz Co, ruling that patent infringement suits can be filed only in courts located in the jurisdiction where the targeted company is incorporated. Justice Neil Gorsuch did not participate in the decision.
