Des Moines-based Kemin Industries Inc. announced today it has filed a complaint with the International Trade Commission requesting an investigation into alleged unlawful and unauthorized importation of supplement products by a competitor that infringe on Kemin’s patent rights. Kemin is seeking an exclusion order by the ITC to preclude continued importation of lutein and zeaxanthin products by OmniActive Health Technologies. Kemin submitted its request in response to OmniActive’s marketing campaigns for the products, which actively induce OmniActive’s customers to infringe Kemin’s patent rights. Kemin said its FloraGLO product is the only lutein brand supported by a patent that shows how ocular antioxidants, such as lutein and zeaxanthin, filter blue light to help protect individual’s eyes. OmniActive, which is based in India with U.S. headquarters in New Jersey, in September sued Kemin seeking a judicial determination that it does not infringe on Kemin’s patents, after Kemin demanded that OmniActive cease and desist from its blue light marketing campaign.
