That appears to only apply to the grants that the Licensor owns. What
about the patent grants from contributors? That was the meat of the
question I sent here a few days ago. Few patent holders would be willing
to essentially grant the right to sublicense a patent to an open source
project (that wasn't their own). In fact most fall far short of that, and
my query was around what a group like the ASF should do.
