It’s the stuff lawyers’ dreams are made of—a coffee monopoly. At least that’s what a bevy of plaintiffs are accusing Keurig Green Mountain Inc. of, as they sue the coffee-maker, according to David Evans of Chadbourne & Parke.

An initial suit was filed back in February, Evans reports, but since then dozens of other companies have piled on. They allege Keurig has created an antitrust market with its cartridges, and that the company “has engaged in various exclusionary practices that have cost them access to the generic k-cup market.” The company’s modus operandi is to price the machines extremely low and then mark up the individual coffees to make its money.
