Multi-Channel Multi-Access Voice Over IP Intercommunication Systems and Methods
A patent family: one line of work, grouped by real continuity rather than by a technology label
inferred from titles. 3 of these applications claim priority to application 60/879,101, filed Jan 8, 2007. 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.
