Ouch! Seems that a company does need a goodwill explicit contract between partners so that in the case of a split or disagreement, the company can use the assets already created, even if copyright is still owned by the parties themselves. Or else all that work can be killed by one spiteful party (or one aggrieved one). Yet... in this case, would that be a good thing? Conundrum.
