Burlesque Hall of Fame sues over use of SASSY LASSY. Neither side has any connection to LASSIE, the famous collie and registered trademark of Classic Media.
Complaint Sassy Lassy
A search at http://tess2.uspto.gov/ turns up a SASSY LASSY mark, serial number 85017127, registered to Cosgrove Presents. LLC. They appear to be using it as the name of a trivia contest in bars. I suppose the question is whether the classification “Arranging, organizing, conducting, and hosting social entertainment events.” would also cover burlesque shows?
