Apple has perpetual rights to LQMT's technology (which includes patents and trademarks) held by CIP in the field of Consumer Electronics.
I don't see why LQMT couldn't sell rights to Eontec, and what Apple would do about it if they did.
You and only legally sell what you legally control. LQMT doesn't have the legal right to sell/license the brand "LIQUIDMETAL" to Eontec in the field of consumer electronics.
