Crosswalk
How Stockpile Stewardship & Sustainment is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 39 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 |
|---|---|---|---|---|---|
| B01D59/00 | Separation of different isotopes of the same chemical element | Separating isotopes, as in uranium enrichment | 24 | 26 | 17,631 |
| G21C19/42 | Reprocessing of irradiated fuel | Reprocessing of irradiated nuclear fuel | 5 | 5 | 9,264 |
| C01G56/00 | Compounds of transuranic elements | Compounds of plutonium and other transuranic elements | 10 | 1 | 3,263 |
| B01D59/44 | Separation by mass spectrography | 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 Stockpile Stewardship & Sustainment: 39 codes on 20,334 documents. The full crosswalk is in the cpc-to-capability.csv download.
