Incorrect, "Bioamber" does very much exist but that new private company has nothing to do with company #4612067 - State of Delaware. As a matter of fact, it has nothing to do with the USA/Canada or shareholders.
Just like there are many "Betty's Cakes" named businesses in the world, there are other Bioamber's. Unfortunately the name that was previously attached to Delaware 4612067 was sold several years past.
So ya, "they" very much do know "Bioamber" exists, just not in it's previous composition.
