Methods and System for Reduced Attenuation in Tracking Objects Using RF Technology
A patent family: one line of work, grouped by real continuity rather than by a technology label
inferred from titles. 17 of these applications claim priority to application 13/566,993, filed Aug 3, 2012. 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.
