to take care of "ensemble".

Please note that "proprietary" does not need the word sole:=)

The term proprietary can more adequately reflect the sense of the conditions: indeed, owner seems to be of less importance for copyright and other questions...

in my opinion owner is enough but if a need for emphasizing "sole" owner exclusive may be correct word.

When describing ownership of this sort, it is common to refer to "title". You might think I am nit-picking here. My suggestion probably changes little in actual fact but I would stick with the idea of the original which puts the accent on the whole of the rights rather than exclusivity of title. By referring to "sole owner" or something similar, the emphasis is changed.
