Margaritaville — both a name and a laidback feel at tourist venues from New York to Costa Rica derived from Jimmy Buffett’s 1977 hit song — is accused of breaching an agreement for the exclusive use of the trademark in the Bahamas.

Boss Investments Ltd. claims it has the exclusive rights to develop and run venues under the Margaritaville trademark, which includes the name, Buffett images and song lyrics, and associated merchandise under a 2014 agreement.
