How System Control & Dispatch is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 109 Cooperative entries in all. A patent family counts when any of its codes, in either scheme and at any office, falls under one of them. Codes since retired are placed under the entries that replaced them.
