What you refer to sounds more like copyright and right to backups and would be broadly in line with a lot of things I have seen there, though Belgium once was a place where people hopped over the border to so as to buy media and dodge levies placed upon writeable media.
Anyway I looked up trademark law in Belgium and found a law firm handling it which gives nice English writeup, I am happy enough to use it as a source here but if we have to use a gov website can we do the French version if it is not provided in English to then give me a fighting chance of translating it/arguing it.

I will also state the rest of the writeup falls in line with UK and US thinking on the matter of trademarks.
Nintendo has games called pokemon red, green, blue, gold, silver and yellow if we are just sticking with colours, and continues to release versions of them upon a variety of consoles to this day. They also make similar logos, signs and such for their works. To that end having words like pokemon, brown and official in your names and sites is not a hard sell for something that could cause confusion in the relevant audience (parents buying their kids games). It says nothing about ignoring trademarks for works that do not garner profit and all the relevant discussion of trademarks in the PDF would apply there, assuming they have registered it in Belgium or the EU (for a bit more money you have the option for an EU wide trademark that all member states get to comply with, and as such most trademark stuff is harmonised between said EU member states) and from memory and stuff I did for Pokemon Uranium the other month then they have it everywhere.
