Court records show that the 60-year-old Patton was stopped on the Isle of Palms on Tuesday night.
He was charged with first offense driving under the influence with a blood alcohol content of less than 0.10. The legal limit for driving is 0.08.
Court documents show he was released Wednesday on a $997 personal recognizance bond. Patton is a native of nearby Charleston.
Isle of Palms police said an incident report would be available later Thursday.
The Associated Press left a message with Patton's agent seeking comment.
