Improved Immunoglobulin Variable Domains

Sanofi

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 9 of these applications claim priority to application PCT/EP2015/060643, filed May 13, 2015. 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.
