If the patent covers code/functionality in the prior releases, and the
patent holder does not grant a license of the patent under
GPL-compatible terms, then I would think that the prior releases would
be in a difficult position, GPL-wise. It could probably be argued in a
court of law, however, that the license holder's prior distribution of
the patented code/functionality with no encumbrances constituted a de
facto license.
