How Emergency Services & Civil Protection is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 335 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 Emergency Services & Civil Protection: 335 codes on 672,414 documents. The 150 most used are listed; the full list is in the cpc-to-capability.csv download.

Match: Through its tools

The classification names the equipment or technology the capability draws on, not the capability. The count says how much is being invented for it, not how well it is done. A62C includes building sprinklers and extinguishers; policing equipment is not covered. The crosswalk is a first pass that nobody has reviewed.
