Summary
Background
An ink manufacturer called Thaddeus Davids Company used the name "DAVIDS'" on its ink labels for many decades and registered that mark on January 22, 1907 under the 1905 trade-mark law’s ten-year clause. Two men, trading as Davids Manufacturing Company, put inks on the market using labels that included "C. I. DAVIDS" and "DAVIDS MFG. CO." The manufacturer sued for infringement and unfair competition. A trial court entered a decree for the manufacturer, a court of appeals reversed, and the Supreme Court then reviewed the case.
Reasoning
The Court examined the statute’s fourth proviso, the ten-year clause, and held that a surname used exclusively as a mark for ten years before the law can be registered and treated as a trade-mark. Registration makes the registrant the “owner” entitled to statutory protection. The Court said protection includes stopping not only exact copies but also near copies that are likely to mislead customers about origin. It also recognized that others with the same surname may still use their own name in trade so long as their use is not misleading. Applying these principles, the Court found the rival’s label use a confusing imitation and therefore infringing.
Real world impact
The Court affirmed the trial court’s injunction preventing the rivals from using "Davids Manufacturing Company" and from placing "Davids" at the top of their ink labels. The ruling confirms that long, exclusive use of a surname can be registered and defended, and that registrants can stop imitators whose labels are likely to confuse buyers.
