Efficient Optical Analysis of Polymers Using Arrays of Nanostructures

Switchback Systems, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 2 of these applications claim priority to application 62/068,599, filed Oct 24, 2014. 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.
