Court documents filed in a Las Vegas trademark case indicate the truTV reality series "Rehab: Party at the Hard Rock Hotel" has been canceled.

Attorneys for the Las Vegas hotel and casino said in documents that the series was not coming back despite being a hit.

"Defendants believe the show was an enormous net benefit to the Hard Rock brand," the documents filed last week said.

The Las Vegas Sun Saturday reported the cancellation announcement contained in the documents came amid a court battle between the hotel and Hard Rock Cafe International, which controls the worldwide Hard Rock brand.

Hard Rock Cafe International went to court in September claiming that the raucous partying displayed in the series was tarnishing the company's good name. The hotel countered the series had actually improved business.
