Serpin Fusion Polypeptides and Methods of Use Thereof

Sanofi

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 8 of these applications claim priority to application 61/502,055, filed Jun 28, 2011. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
