Hi,
When you register a trademark (something that I've done many many times) you specify a product/service group(s) that you are/will be using the mark in. At least for those group(s) you get exclusive rights to sell , market etc. products with the mark. With other words you get far broader protection than just for the concrete product you are using the mark for.
For example the French hiking association has registered all it's marks in group 41 (and in a lot of other ones too): KLASSE 41 Erziehung; Ausbildung; Unterhaltung; sportliche und kulturelle Aktivitäten.
I havn't read the pdf, but I've a question. If you register a trademark, you can prohibit someone else to name your product with the name your trademarked? E.g. Mercedes can prohibit you to call their cars "Mercedes"?
