Crosswalk
How Assured Space Access is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 68 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 |
|---|---|---|---|---|---|
| B64G1/002 | Launch systems | Space launch systems, including air launch and reusable boosters | 4 | none | 4,523 |
| B64G5/00 | Ground equipment for vehicles, e.g. starting towers, fuelling arrangements | Launch-site ground equipment such as towers and fuelling | 2 | 1 | 2,636 |
| B64G1/14 | Space shuttles | Space shuttles and reusable spaceplanes | 1 | 1 | 1,546 |
| F02K9/00 | Rocket-engine plants, i.e. plants carrying both fuel and oxidant therefor; Control thereof | Rocket engines | 61 | 48 | 55,721 |
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 Assured Space Access: 68 codes on 62,233 documents. The full crosswalk is in the cpc-to-capability.csv download.
