You didn't do digging, he listed that in the original blog post earlier today.Just did some digging around on the LA Secretary of State website.
For what it's worth, in addition to "The New Orleans Louisiana Angles, LLC" there is also a listing for "The Angels of New Orleans, Louisiana & Logo." Both are registered in Metairie. Neither have "details" available yet, which leads me to believe that both are very recent reserved names.
Also, I couldn't find an entry for "The New Orleans Louisiana Spirit, LLC," but did find one for "The Spirit of New Orleans, Louisiana & Logo." As with the Angels entry, it was registered in Metairie and lacks available "details."
I'll keep digging to see if other names pop up.
EDIT: I fiddled with the search terms and was able to find "New Orleans Louisiana Spirit, LLC." I'm not sure why it only showed up when I searched "New Orleans Louisiana, LLC." It too is registered in Metry and appears new.
Other fun facts I've learned:
Benson's trademark on the Pelicans expires on May 18, 2012.
Someone named Roy J Rodney, Jr., re-registered what seems to be the old New Orleans Brass logo in April 2012. From the description it looks like he is just going to be making shirts/hats with it.
