A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 4 of these applications claim priority to application 15/475,487, filed Mar 31, 2017. 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.
