That first link isn't quite right.

Thanks. Fixed it.

But, wouldn't that be the same as trying to trademark, Irish or English? Which, correct me if I'm wrong would not be possible.

Is this because Ulster-Scots or Ullans is not an official language?

Strange one.

I doubt that this trademark would be enforceable - all one would have to do is show prior usage in the particular area that the trade mark applies to - something which would not be hard to do in the case of Ullans.
I don't think that the trademark was allowed because of the status of Ullans or anything like that but rather because who ever dealt with the application didn't understand what Ullans is and how widely used it is. I'm sure that had the Paten Office done a bit of research they would have disallowed this application.
