[1] says "When licences are acquired as part of an asset transaction, the contracts are taken over. In that case, the selling and buying parties need the cooperation of the licensor. This cooperation can take place before or possibly after the takeover. If the licence is not transferable, there will in principle not be a legally valid transfer unless the IP right holder in question gives his consent to the transfer of the licence."
Do you have a link to suggest that these definitely-are-lawyers are wrong in this interpretation?
