Pure Encapsulations, a Sudbury company that makes and sells non-allergenic dietary supplements, sued lean Living and Tsalevich, as well as their principals, for Lanham Act and common law unfair competition, unfair and deceptive trade practices, and tortious interference with Pure Encapsulations’ agreements with its authorized resellers. Pure Encapsulations sells solely through authorized resellers and implements strict quality control requirements on their resellers. According to the complaint, the defendants operate Amazon storefronts, through which they sell Pure Encapsulation products that were purchased from authorized resellers. Pure Encapsulations asserts that the defendants mishandle these products, resulting in numerous complaints and poor on-line reviews, to the detriment of Pure Encapsulations. For example, customers complain if having received products whose safety seals had been tampered with; products with the incorrect number of pills or incorrect dosages; counterfeit products; and products that should have been, but were not, refrigerated. Pure Encapsulations seeks monetary and injunctive relief, as well as an order that the defendants take all action to remove references to Pure Encapsulation products from all sites on which defendants had listed them for sale.
