> I meant trademarked I guess
What I mentioned earlier is the gist of whether or not you can use a name.
Trademarked, pattented. meaning some company payed 80k/120k for a concept/name.
If you simply place a copyright sign, or notice, or a trademark emblem ... and its not in fact pattented or copyrighted at all, it doesnt really make any difference.
A disclaimer or use policies definition about content does.
Copyright, and trademarks, are different things, and a patent is separate again.
* If I produce a long gash of dribbling words for a product, a book, newspaper, etc, that's copyright. Technically, you don't need to register a copyright [in most countries], but damages claims are less rewarding.
* If I invent a new product, even unique features, I can register those parts which are unique as a patent. Normally, I have to prove that I was the inventor [although corrupt & bias US patent office does cheat].
* If I make up a unique name, or logo, that's a trademark. You're supposed to only be able to register trademarks which aren't in common use, but again, the corrupt US patent office cheats [example UGG boots, US company in the 1990s got a trademark on the name, and then hit the lawyers on every small business in Australia which made them - some having sold UGG boots for over 50 years].
But, discounting the corruption, a trademark also only applies for the industry in which the trademark is used for. For instance, Brothers is trademarked for electronics. But you can have Brothers clubs, and probably Brothers Clothing [if somebody else doesn't have one on that].
Further on this, a trademark only applies where there can be competition for similar buying demographics. For instance, a franchise selling ice creams from a van will probably lose if they tried to take a 5 star restaurant to court over a trademark violation.
Finally, trademarks can be eroded by common use. Polo Shirts used to be a trademark, but common use means the trademark became worthless.
So, there's a lot of things in relation to names and trademarks.
