Dry eye is an interest of mine. I saw this in the news on Friday I think, and the resulting statements from Allergan and the Native American Tribe (Saint Regis Mohawk Tribe). It's really a brilliant move by their patent lawyer. Native American tribes have sovereign immunity to IP challenges. This helps extend the monopoly on a drug that makes up a very large part of Allergan's profit (besides Botox).
