Crosswalk

How Spectrum & Broadcasting is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 215 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.

CPC and IPC codes are the codes in use on patent documents, at any office, that fall under the entry. Documents is the larger of the two schemes' counts of documents carrying one of them. An entry with no IPC codes can be told apart only in the Cooperative scheme.

The Cooperative codes in use that count towards Spectrum & Broadcasting: 219 codes on 510,566 documents. The 150 most used are listed; the full list is in the cpc-to-capability.csv download.

The capability is itself a technology or a kind of physical system, and the classification names it. Spectrum management is weakly covered; H04W16/14 also falls under the Mobile & Wireless rule H04W. The crosswalk is a first pass that nobody has reviewed.
