Professor Chaos posted:Interestingly, Lionel filed for a trademark on the Super O name in 1997 and 2003.
The 1997 application was abandoned.
The 2003 application was granted in 2006, but subsequently cancelled, probably because Lionel did not use the mark in commerce.
Great work by you and gunrunnerjohn regarding the patent and trademark. I had some vague recollection of a filing by Lionel around the time they made the track Super "O" Bob referenced. Perhaps it was the 2003/6 Trademark you referenced.
Great detective work!
