And don't forget that US patents and EU patents differ. Most of the US trash patents in electronics can't be patented in the EU, as the patent law is not as permissible. Even the US is coming to terms with this (i.e. the summer rejection of Apples pinch-to-zoom patent in the US).

Since Jolla is not selling directly in the US, I assume patents can't be infringed on in that market anyway.
