Looking at this from the above link it makes it look like he trademarked the single word Maniac. Maybe I'm just not understanding how it works.
"On Wednesday, February 21, 2007, a U.S. federal trademark registration was filed for MANIAC by MANIAC CUSTOM LURES, LLC, BRIGHAM CITY, UT 84302. The USPTO has given the MANIAC trademark serial number of 77112175."
