> I don't know EU law, but I don't buy this argument. Some very common words are trademarkable (e.g. Apple) in certain trade contexts. You seem to be arguing only a neologism can be trademarkable.
Apple is not a great example[1]
>And that doesn't touch on the "not used for chicken sandwiches" part, which seems to be a key part of the actual argument.
From what I can tell, they are using that to prove that Mac can't be used to enforce a blanket ban - which is what McD's wanted.
> In the context of anything, or in the context of the fast food market? Because I think it would be legitimate to block a new fast food restaurant called "Kentucky Chicken" on trademark grounds.
Even if you sold chicken in Kentucky? I think it is not trademarkable IMO, because it is obvious that it will conflict with something in the past , preset or future. It is very antagonistic. Having said that, we locally have this restaurant "Ken's Fried Chicken"[2] and they have managed to ape KFC for 20+ years. We also had a video chain called "Blockbusters" and "Blockbuster" sued them out of business, despite the former existing in the UK for many years before the latter made it here. I guess it is down to the angle they court is pitched.
