TreeHouse Foods issued a complaint against Green Mountain in the United States District Court for the Southern District of New York asserting that the Keurig owner used its dominance in the brewer market to bar rivals from competing with its "K-Cup" packages of coffee and other hot beverages. With its new Keurig 2.0 machine and anti competitive lock-out technology, which prevents use of K-cups not designed by Green Mountain, the company is trying to drive out other players from the market. TreeHouse also claimed post patent expiration, Green Mountain is pursuing exclusive deals with suppliers and distributors in an attempt to crowd out competition and amount to an exertion of monopoly power in the K-cup market.
