David: I'm confused.....if Bio was the patent applicant, then wouldn't Bio own the patent? I'll be the first to admit I don't know patent law - I'm not that kind of lawyer, which is a legal specialty with a separate bar exam to pass - but, even if Bruno joins MCCY, if he does not own the patent, then, even though he may be the inventor, if he did not retain intellectual property rights in what he developed that Bio patented, then MCCY cannot use SDS without Bio's permission.
Now, if Bruno developed something ELSE, that doesn't incorporate Bio's patent, and kept the IP 9intellectual property) rights to himself, then HE is in the driver's seat. We would then have a completely different story.
