Kotabs v. Kotex

United States Court of Appeals for the Third Circuit
50 F.2d 810 (1931)

Facts

Kotex Co. (plaintiff) manufactured and sold sanitary pads sold under the brand name Kotex. Leading newspapers and periodicals would not permit Kotex Co. to advertise its product by plainly explaining how and why to use it, so Kotex Co. developed and implemented advertising campaigns based solely on its brand name. Its ads would include the name Kotex in some prominent way, such as on a box tucked under a nurse’s arm, and rely on the curiosity of consumers to ask their medical professionals about the product to learn how it was used. The campaign was very successful. A new company called Kotabs Inc. created a product called Kotabs, named by combining the words Kotex and tablet. Kotabs were pills developed to reduce menstrual pain. Kotex Co. sued Kotabs Inc. for trademark infringement, and Kotabs Inc. defended itself by arguing that Kotabs were in a different class of product than Kotex and therefore did not infringe on the Kotex mark. The trial court found that Kotex Co. had a valid trademark and that Kotabs Inc. had infringed the trademark. The court enjoined Kotabs Inc. from using the Kotex mark and the word Kotabs in marketing its products. Kotabs Inc. appealed.
