This would have significance if the licensor is also the patent
holder. The licensee potentially could argue the right to copy/modify
hence implied the required rights to the patent (for this programme
anyway) - But i've no idea how patent and copyright law can interact
and whether such argument would be allowed.
It's definitely not interesting if the patent holder is a 3rd party
(which is the case for most patent disputes, no?).

This just clarifies that one can not distribute under the GPL if
there are other factors that would restrict distribution (eg lack of
(this reinforces above argument, that licensor must grant rights to a
required patent to distribute under GPL, that lack of a licence might
be a implied patent licence - but that'd be a very strange case..
like IBM shipping linux and suing a customer for violating RCU
patents - and not applicable to case where patent holder is not a
party to the licence.).

So the GPL can be used with geographical restrictions, if needs be,
due to copyright/patent restrictions.
I dont quite see how GPL helps with 3rd party patent infringement
