Ok. Well, Texas has been recognized by the US government since 1845. Doesnt mean the governor can stop Chevy from making the Texas Edition Silverado - even if they aren't made there. Cant stop a chain restaurant from selling big steaks and calling itself Texas Roadhouse. Texas chili anyone? Texas barbecue? Well, technically, ANY barbecue that happens in Texas is a Texas Barbecue. Any barbecue facilitated by a Texan in any other state or province could be termed a Texas barbecue. What if I learned how to do a proper Texas barbecue but did it in New England? I don't think Ted Cruz has a chance at stopping me.Well I'm no lawyer and you can't trademark generic things with no ownership rights such as races or religions, but you can trademark organizations with a formal structure and membership. A tribe such as the Cherokee has had that recognition from the US government for quite some time. Regions don't really apply here but they can also be Trademarked if they tangibly identify the item. Familiar examples are wines such as Champagne or Bordeaux which much originate from those areas to be legally recognized as such.
How many items with the word American have you found that were made in China. Or how about Swiss Army Knives with American flag scales on em. Nothing can be done about it.
Champagne, Bordeaux and even Chianti are all inanimate objects (that may assist in animating those partake too much), substances.
You cant trademark a race of people. Now, if there was a specific artifact produced by the Cherokee Nation, and they trademarked that, well that they can do.
My 4 cents, I guess.
