How Additive & Precision Manufacturing is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 366 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.

The capability is itself a technology or a kind of physical system, and the classification names it. General machine-tool subclasses (B23Q, B23B, B23C, B24B) are left out as too broad, so the precision side is represented only by control and non-conventional machining. The crosswalk is a first pass that nobody has reviewed.
