I think you'll probably find that the answer is 'it depends' unless you go into the specifics. Each country is different, and there is also consumer protection legislation as well as trademark and patent law to consider. I think we have some a trademark lawyer on the forum who may be along with some info.
A casual legal answer is always 'it depends', rightly so and indeed it does. Lawyers then make their money testing the 'it depends' in or out of court.
