Kenny Chesney is all fun and games onstage, but when it comes to his business, he gets serious. That's why the singer filed a copyright lawsuit in federal court this week.

Chesney owns the trademark for a logo which features a guitar leaning against a palm tree -- a clear tribute to his love of island living. The star contracted with licensing company Latitude to use his name and logo to sell merchandise, and was supposed to have final approval of any agreements between Latitude and other companies, but that's not how it panned out.

A company called T&M Enterprises began producing merchandise and gear with Chesney's logo, but without permission, according to the lawsuit, the Tennessean reports.

Chesney told the company to put an end to the production of merchandise, and the two reached a settlement agreement in January 2013 that would allow T&M to sell the remainder of its items. However, instead of abiding by the agreement, the company has continued to sell the merchandise.

“Under the terms of the settlement agreement, defendant T&M agreed to stop using the Chesney (intellectual property) in connection with the manufacture, sale, advertising and promotion of its goods worldwide,” the lawsuit states.

As a result of the infringement, the 'Pirate Flag' hitmaker and his team needed to take action. “We believed we had an equitable settlement in place,” a statement from a Chesney spokesman says. “As time has passed, we realized that, in fact, the defendant had no intention of honoring the agreement. Regrettably, we were forced into taking further legal action. The details of our complaint are provided in the lawsuit filed in Nashville.”

It goes to show that even in paradise, there can be trouble.
