I'm interested in seeing how the patent issues turn out around reiterated drugs in the future. I predict that they will be and remain patentable. I'm no lawyer, but deuteration does not seem obvious. Yes the idea that you can swap out hydrogen for deuterium is obvious, but the idea that deuteration will have a meaningful effect on a specific drug is not. For some drugs it may do nothing while in others it will.
