How Batteries & Energy Storage is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 822 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 |
|---|---|---|---|---|---|
| H01M | Processes or means, e.g. batteries, for the direct conversion of chemical energy into electrical energy | Batteries: cells, electrodes, electrolytes, casings and manufacture | 994 | 458 | 9,566,481 |
| H01G11/00 | Hybrid capacitors, i.e. capacitors having different positive and negative electrodes; Electric double-layer [EDL] capacitors; Processes for the manufacture thereof or of parts thereof | Supercapacitors and hybrid capacitors | 44 | 44 | 301,626 |
| H01M8/00 | Fuel cells; Manufacture thereof | Left out | |||
| H01M2250/00 | Fuel cells for particular applications; Specific features of fuel cell system | 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 Batteries & Energy Storage: 1,038 codes on 9,868,107 documents. The 150 most used are listed; the full list is in the cpc-to-capability.csv download.
