I get parsing errors in my brain when reading this. While I understand
that you do not impose any new restrictions (as per #10), I still
don't understand how you can claim that #11 (the first two quotes
above) has no relevance in your case. To me, it seems that the example
in #11 (the first quote) matches this case exactly -- assuming that
Google has a patent license that does not permit royalty-free
I also understand that the LGPL doesn't explicitly "require [anyone]
to pass along patent rights we may have obtained elsewhere". However,
it seems quite clear that the intention of #11 is to say that you
cannot redistribute the code unless you do exactly that.
What am I missing?
