how much right do I have on my project, if there are patches by others?

I don't believe they do, because the original work was not written with 
the specific intention of integrating with that particular patch.
I believe that the second paragraph of the legislative commentary applies.

However, if you were right, that would fundamentally undermine copyleft 
licences, as, a contributor could contribute a small but non-trivial 
patch and then relicence the whole product under their proprietary licence.
