The Danbury-based Armor All/STP Products Co. has filed a federal trademark infringement and counterfeiting lawsuit against one of its competitors, claiming intentional misuse of the “High Mileage” phrase and logo.

In a 36-page lawsuit filed July 7 in U.S. District Court in Hartford, Armor All/STP alleges that Arlington, Texas-based TSI Products Inc. began using its marks on some of its “Avalanche” products beginning in April 2016. The lawsuit, which claims violations under the Connecticut Unfair Trade Practices Act and the federal Lanham Act, says the products are commonly used for adding refrigerant to vehicle air conditioners.

The lawsuit asserts that William Quest, one of three founders in 2014 of TSI, “has actual and constructive knowledge of the existence of plaintiff's High Mileage marks and actual and constructive knowledge of the plaintiff's sale of A/C Pro and High Mileage-branded products” due to his long-standing involvement in the automotive refrigerant industry “and previous business dealings with plaintiff's direct corporate predecessor.”
