United Drug Co. v. Theodore Rectanus Co.
Headline: Trademark dispute over 'Rex' — Court affirmed that a local Kentucky seller can keep using the mark, blocking a Massachusetts company’s attempt to stop local sales and limiting its territorial reach.
Holding: The Court held that a Massachusetts company cannot bar a Kentucky firm that in good faith built a local business under the 'Rex' mark from using it in Louisville, since trademark rights attach to actual local trade use.
- Allows local sellers to keep using a mark they built up in their area.
- Limits trademark reach when the owner never used the mark in that territory.
Summary
Background
A Massachusetts corporation bought a long-used medicine brand called "Rex" that began with Ellen M. Regis in New England. Separately, a Louisville druggist named Rectanus began using the same word as a mark for a different medicine around 1883 and built a local trade. The Massachusetts company sued in 1912 to stop the Kentucky company from using "Rex" in Louisville; lower courts reached different results before this Court decided the matter.
Reasoning
The Court addressed whether an earlier user who kept the business confined to a distant region can prevent a later, independent local user who in good faith built up a trade under the same mark. The Court explained that trademark rights depend on use and business good-will, not mere prior adoption or out-of-state registration. Because Rectanus and his successor had long, good-faith local use and recognition in Louisville, and Regis’s use had been limited to New England, the Massachusetts owner could not bar the Kentucky firm from continuing its established local use.
Real world impact
The decision lets a local business that in good faith created a trade under a mark continue using it in its market even if an earlier adopter used the same mark elsewhere. It limits the reach of trademarks that were not actually used in a given territory and confirms that registrations or distant use do not automatically create territorial rights.
