277 F. 951 | 4th Cir. | 1921
In this suit for infringement of a copy-_ right, plaintiffs had a decree and defendant appeals.
Both parties manufacture and sell piston rings for replacement purposes; they are active competitors, in that business. Beginning in 1913, and each year since down to 1919, the plaintiffs, or their predecessors-in title, have published and distributed a printed pamphlet entitled “Dimensions of Piston Rings.” This pamphlet lists the various makes of motor vehicles in alphabetical order, and gives for each the year, model, bore, groove, size, and number of rings, and the like. It appears to be an excellent advertisement, and also a valuable reference book for repairmen to use in ordering piston rings for their customers. Indeed, without the data furnished by such a compilation, it would be practically impossible for dealers to keep a supply of rings in stock. Each yearly issue of this pamphlet has been copyrighted, and it is the issue of 1919 which defendant is charged with infringing. For the purpose' of detecting infringers, plaintiffs have, for some years past, included in their annual lists a number of fictitious or “trap” models; that is, nonexistent cars, and -rings that are never used. In the edition of 1919' there were 12 of these decoys.
Defendant’s pamphlet, styled “Piston Ring Size Directory,” was issued about the 1st of June, 1920. In December of the previous year, the Motor World, a trade journal, had published a catalogue of piston ring dimensions. Except that models prior to 1916 were omitted and. passenger cars separated from trucks, this catalogue was a reproduction of plaintiffs’ compilation, including 10 of the 12 fictitious models-
The decree appealed from will be affirmed.
