My experience is in basis the same as above, indeed if it comes down to it there is still a judge who will also apply some level of, let's say, common sense.
Though my experience is on business cases, luckily no private needs or issues, I trust that if a Private person is affected such will count even more. From a company you may expect a certain level of knowledge and expertise, for a private person that is far less applicable.
The issue with these kind of cases is mainly the threat the (big) company is to a single Private person. To make it to court you'll need to spend some serious money first and above all you'll need a long breath, as such cases can take years before a (first) judgement is spoken. You'll meanwhile be unsure if and to what extend your spendings will be refunded.
Hence in most cases the companies expect a private person to simply retreat and revert or correct their actions. Often such cases are initiated from eager lawyers or legal employees.I mean the owner of the restaurant at the end of the street would never complain, instead he would be honoured if I made his place as a mod.
So it's a risk when using large brand labels, though I think with the above as noted also by DH-106 we will stand strong if needed. Might one receive a legal note just be cautious in the wording of your reply.
