Dominick & Haff, the silversmiths, of 860 Broadway, New York, inform the trade in this issue that design patent No. 18,614, for fire ornamentation of the handles of spoons, knives, forks and similar articles, granted to them September 18, 1888, has recently been sustained by the United States Circuit Court in a suit brought against prominent manufacturers who were infringing upon it, and an injunction has been granted. The design referred to, which has proved very salable, is illustrated in their advertisement. It is the declared intention of Dominick & Haff to continue to prosecute vigorously all who may be found infringing upon any of their patented designs.
