Crosswalk
How R&D & Testing Facilities 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 |
|---|---|---|---|---|---|
| G01M9/00 | Aerodynamic testing; Arrangements in or on wind tunnels | Wind tunnels and aerodynamic testing | 8 | 5 | 36,711 |
| G01M15/14 | Testing gas-turbine engines or jet-propulsion engines | Testing gas-turbine and jet engines | 1 | 1 | 12,809 |
| F02K9/96 | Rocket-engine plants, i.e. plants carrying both fuel and oxidant therefor; Control thereof characterised by specially adapted arrangements for testing or measuring | Testing and measuring of rocket engines | 1 | 1 | 2,868 |
| B64F5/60 | Testing or inspecting aircraft components or systems | Testing and inspecting aircraft and components | 1 | 1 | 20,709 |
| B64G7/00 | Simulating cosmonautic conditions, e.g. for conditioning crews | Simulating space conditions on the ground | 2 | 1 | 4,690 |
| F42B35/00 | Testing or checking of ammunition | Testing of ammunition | 2 | 2 | 5,049 |
| F41A31/00 | Testing arrangements | Testing arrangements for weapons | 2 | 2 | 2,549 |
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 R&D & Testing Facilities: 17 codes on 69,394 documents. The full crosswalk is in the cpc-to-capability.csv download.
