Hmm. Yeah, you're right.
Only that you don't share the actual RTL perse but only use it for simulation
and generating a netlist and from that a .def file.
It's kind of a legal discussion[1] whether a DEF/Magic/GDS2 layout is actually
covered by copyright or whether one has to register a Gebrauchsmuster
for it already.
