"Furthermore there is no such exemption for trademark or patent infringement in any legal system that I'm familiar with, but I'm happy to be proven wrong on that" UK Patents Act 1977, Sec. 60 (5) (a): "An act which, apart from this subsection, would constitute an infringement of a patent for an invention shall not do so if - (a) it is done privately and for purposes which are not commercial;" As to trademark infringement I agree that there is no explicit exemption for private use. But on the other hand I think it is not necessary - trademark infringement is putting trademarked goods on the market so it's not private by definition.
