I was in the Haunted House business a few years ago. I worked for one in Indianapolis (FRIGHT MANOR). I wanted to see if anyone knew that answer to my question.
I one time, attended a class at Hauntcon. While at this class, I remember someone said that they had the name SCAR-E-OKEE trademarked. I believe his name was Tim. If anyone has this name trademarked, or know who does, please post back on here, or shoot me an email at firstname.lastname@example.org.
