Harmony Gold, the U.S. rights-holder for the Macross property, is sending letters to retailers and importers of Japanese Macross products, telling them to cease and desist, according to Anime News Network. The retailers involved, as far as we know, have been mail order/Internet retailers, not brick and mortar stores. The letter asked not only that the retailers cease and desist sales and marketing of the products, but also that they identify the source of the products, turn over inventory to Harmony Gold, and agree to avoid parallel imports in the future.
