Meanwhile, sugar shortages during World War I hurt sales of Archibald Query's Marshmallow Creme. Query sold his recipe in 1920 to H. Allen Durkee and Fred L. Mower from Swampscott, Massachusetts. The two men began selling the product through their company, Durkee-Mower Inc. They renamed the product Toot Sweet Marshmallow Fluff. Durkee-Mower continues to sell the product under the name Marshmallow Fluff. The sandwich was not called a Fluffernutter until 1960. "Fluffernutter" is a registered trademark of Durkee-Mower. The company's U.S. trademark registrations for the term cover only ice cream and printed recipes. In 2006, Durkee-Mower sued Williams-Sonoma Inc. in the United States District Court for the District of Massachusetts, alleging that Williams-Sonoma infringed on its trademark by selling a marshmallow and peanut butter chocolate-covered candy under the "Fluffernutter" name.
