Substituted Pyrazolo[1,5-a]pyrimidine Compounds as TRK Kinase Inhibitors (2011)

Array Biopharma Inc.

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 PCT/US2009/061519, filed Oct 21, 2009. 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.
