Either “Entire” shouldn’t be there, as Norway isn’t in the EU, or “EU” should be “European Economic Area” (https://en.wikipedia.org/wiki/European_Economic_Area).
My Norwegian is almost nonexistent, but I think it’s the latter. It makes more sense to my understanding of law (why else would a Norwegian claim extend to EU countries?) and the Norwegian title mentions “EU/EØS”, and that matches the Norwegian name of that Wikipedia page (https://nn.wikipedia.org/wiki/EØS)
If so, it also would apply to Iceland and Liechtenstein.
