If I'm licensing from my company, what legal mechanisms force that asset to still be owned by my company? Can I not license it to myself under some vague EULA terms in which the company gets it back upon my passing, but I'm forbidden from reselling (and thus it's not an asset for me either)? If the key to this is the "licensing" of a product forbidding resale, I'm not seeing how that isn't a financial black hole into which assets disappear.
