Substituted IMIDAZO[1,2B]PYRIDAZINE Compounds as TRK Kinase Inhibitors

Array Biopharma Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 6 of these applications claim priority to application 61/099,030, filed Sep 22, 2008. 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.
