As part of the celebration of St. Patrick's Day (even though this is being written the day after), I want to note something I found out when I visited my hometown of El Paso a couple of weeks ago.
Growing up in this border city, I attended Cathedral High School, an all-boys school run by the Christian Brothers. This year the small (400 students) school in central El Paso celebrates its 85th anniversary.
However, just recently and unfortunately, the University of Notre Dame notified the school that it could no longer call itself the "Fighting Irish" or use the logo of the leprechaun figure due to copyright infringement. Notre Dame claims it alone holds the copyright to this nickname and logo.
Apparently there are other Catholic schools like Cathedral in the country that also use the Notre Dame nickname and logo and the university notes that when it finds this out it notifies them to cease.
