Variety has USPTO trademark registration for Backyard in the category of the lawn and gardening supplies. Variety has been using the trademark Background in the sale of grills and grilling supplies since 1983.
Before the Court is a case in which a larger company with deeper pockets for litigation selected a product name with the same dominant word as a smaller company by which to sell the same and similar items as that smaller company. The larger company knew of the smaller company’s use — and trademark — when it decided to use the name, but the larger company used it anyway
