| I think you're missing some nuance in your understanding of trademarks with all due respect. The core use of trademark protection isn't a commercial use, necessarily. Rather, it's the act of infringing on the trademark holder's commercial use. So, if Waffle House is selling Waffle House t-shirts, and a business next door is giving away free Waffle House t-shirts that they printed - then yes, Waffle House would very likely win a lawsuit against someone giving away waffle house t-shirts. Basically if someone is giving away or, especially, selling something that causes a confusion against the original trademark, then yes, the trademark "must" be protected. By "must" I don't mean it's legally required. I just mean you're going to have a harder time in court if you need to pursue legal action against a company or person if there's a precedent you have not actively protected the trademark in other instances. edit: and in this case, the site was causing confusion, so they sent a C&D. Also as the other commentor mentioned, the logo is trademarked. |
There is a difference when treating well-known trademarks (say Coca-Cola, Sony, Google), however I doubt Waffle House gets over the threshold set for that for being too local (I counted at least 20 states that do not have one) and not sufficiently known by all demographics (if you want to know more read up on the Lanham Act).
Full disclosure: I am a TM lawyer, but not in the US. YMMV and what I write here is no legal advice ;-) since only gathered from US colleagues' explanations regarding cases clients had in the US.
The notorious/well-know concept is part of an international treaty (Art. 6bis of the Paris Convention) and its interpretation is similar in most western countries, so I'd expect the US interpretation to not be that far off.
