Crosswalk
How Maritime Security & Constabulary is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 3 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.
| Entry | Title in the scheme | Why it is chosen | CPC codes | IPC codes | Documents |
|---|---|---|---|---|---|
| G08G3/00 | Traffic control systems for marine craft | Monitoring and control of vessel traffic | 1 | 1 | 6,101 |
| G01S13/917 | Radar or analogous systems specially adapted for specific applications for traffic control for marine craft or other waterborne vessels | Radar for controlling marine vessel traffic | 1 | none | 434 |
| F41H11/05 | Net barriers for harbour defence | Net barriers for harbour defence | 1 | 1 | 416 |
| G08G3/02 | Anti-collision systems | Left out |
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 Maritime Security & Constabulary: 3 codes on 5,691 documents. The full crosswalk is in the cpc-to-capability.csv download.
