Crosswalk
How Sea Control is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 17 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 |
|---|---|---|---|---|---|
| B63G1/00 | Arrangements of guns or missile launchers; Vessels characterised thereby | Guns and missile launchers on warships | 1 | 1 | 900 |
| B63G3/00 | Arrangements of ammunition stores or handlers; Vessels characterised thereby | Ammunition stores and handling on warships | 4 | 4 | 486 |
| B63G5/00 | Vessels characterised by adaptation to torpedo launching | Vessels adapted for launching torpedoes | 1 | 1 | 148 |
| B63G9/00 | Other offensive or defensive arrangements on vessels against submarines, torpedoes, or mines | Ship defences against submarines, torpedoes and mines | 5 | 4 | 2,180 |
| B63G11/00 | Aircraft carriers | Aircraft carriers | 1 | 1 | 563 |
| B63G13/00 | Other offensive or defensive arrangements on vessels; Vessels characterised thereby | Other warship defences, including camouflage and stealth | 5 | 2 | 3,175 |
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 Sea Control: 17 codes on 7,261 documents. The full crosswalk is in the cpc-to-capability.csv download.
