It does not necessarily follow that a mere copyright license has no
implications for some relevant subbundle of the copyright licensor's
patent rights, unless perhaps, as with [my reading of] CC0 4a, the
license (or waiver+fallback license) is quite explicit in removing the
possibility of its grant of permissions as extending in any way to the
patent domain.

Again, there is not necessarily any conflict between those two ideas.
