Crosswalk
How Space Domain Awareness & 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, 5 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 |
|---|---|---|---|---|---|
| B64G3/00 | Observing or tracking cosmonautic vehicles | Observing and tracking spacecraft | 1 | 1 | 2,895 |
| B64G1/68 | Arrangements or adaptations of apparatus or instruments, not otherwise provided for of meteoroid or space debris detectors | Detectors of space debris and meteoroids on spacecraft | 1 | 1 | 409 |
| B64G1/56 | Protection against meteoroids or space debris | Protecting spacecraft against debris and meteoroids | 1 | 1 | 586 |
| B64G1/1078 | Maintenance satellites | Servicing, inspection and debris-removal satellites | 2 | none | 1,716 |
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 Space Domain Awareness & Control: 5 codes on 5,255 documents. The full crosswalk is in the cpc-to-capability.csv download.
| Code | Title | Under entry | How placed | Documents |
|---|---|---|---|---|
| B64G3/00 | Observing or tracking cosmonautic vehicles | B64G3/00 | In the scheme | 2,544 |
| B64G1/1078 | Maintenance satellites | B64G1/1078 | In the scheme | 976 |
| B64G1/1081 | Maintenance satellites for debris removal | B64G1/1078 | In the scheme | 740 |
| B64G1/56 | Protection against meteoroids or space debris | B64G1/56 | In the scheme | 586 |
| B64G1/68 | Arrangements or adaptations of apparatus or instruments, not otherwise provided for of meteoroid or space debris detectors | B64G1/68 | In the scheme | 409 |
