I think the legal issues start occurring even sooner than that. If the person is dead, they can't enter into contracts, and the US has a rule against perpetuities, so at some point it's not clear exactly who can keep the company from during away all their biological samples.

If the person is not dead, then at what point have they effectively been kidnapped if the company chooses not to revive them? (Maybe someone says the technology is ready, maybe someone else disagrees.)
