A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 5 of these applications claim priority to application 12/131,267, filed Jun 2, 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.
