Canada’s Club Coffee said it was suing K-cup coffee pod maker Keurig Green Mountain Inc for engaging in anti-competitive measures to maintain a near monopoly and keep single-serve coffee prices artificially high. Club Coffee is seeking $600 million in damages and said Keurig was spreading “baseless and disparaging lies” about competitors’ coffee pods to mislead consumers and coerce third parties into exclusive agreements. Club Coffee said it made coffee pods for Keurig brewers and sold them at lower prices than Keurig’s own K-Cup packs.
