RALEIGH, N.C. -- In the world of college nicknames, there may be room for only one top dog when it comes to the Wolfpack.
North Carolina State University isn't happy that Loyola University in New Orleans calls its sports teams the Wolfpack, a name trademarked by the Raleigh-based school.
NC State sent a letter to Loyola last month raising its objections, and lawyers for both schools are in talks.
Loyola began using the name in the 1930s, but it had no athletic program between 1972 and 1991. NC State registered the Wolfpack trademark in 1983, the year its men's basketball team won the NCAA tournament.
Rutgers law school professor John Kettle says trademark owners risk losing their claim to a property if they don't enforce their ownership rights.
