It was recently announced that Cathedral High School of Indianapolis, Indiana, has agreed to a request made by the University of Notre Dame asking Cathedral to stop using Notre Dame’s leprechaun logo. This logo (shown here as registered with the USPTO) was used by both schools until last week, where upon receipt of the request from the general counsel for Notre Dame, officials at Cathedral decided not to oppose it. According to the South Bend Tribune news article (link below), the request to stop using the logo pertains to items for sale by Cathedral, and does not apply to the use of the logo on the floor of the school gymnasium or the practice football field. A brief USPTO search revealed two trademark registrations for the leprechaun logo (U.S. Trademark Reg. Nos. 1,229,591 and 1,905,508), the earlier one registered in 1983 and claiming a first use of July, 1966. According to Cathedral’s website, Cathedral High School was founded in 1918 by Bishop Joseph Chartrand, and “[b]y a unique arrangement, the Indianapolis Catholic Diocese owned Cathedral, but engaged the Holy Cross Brothers of Notre Dame to serve as faculty.” Priests from Holy Cross, according to the South Bend Tribune article and confirmed by Notre Dame’s website, also founded the University of Notre Dame back in 1842. Cathedral plans to discuss the use of alternative leprechaun logos with Notre Dame.
