Crosswalk
How Spectrum & Broadcasting is matched to the patent classifications. The entries below were chosen for it; each stands for itself and everything beneath it in the scheme, 215 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 |
|---|---|---|---|---|---|
| H04H | Broadcast communication | Broadcast communication systems | 184 | 172 | 324,390 |
| H04N21/61 | Network physical structure; Signal processing | Network structure for television distribution | 16 | 1 | 83,508 |
| H04N7/20 | Adaptations for transmission via a GHz frequency band, e.g. via satellite | Television transmission by satellite and microwave bands | 1 | 1 | 13,163 |
| H04W16/14 | Spectrum sharing arrangements between different networks | Spectrum sharing between networks | 2 | 2 | 73,671 |
| G01R29/08 | Measuring electromagnetic field characteristics | Measuring electromagnetic field strength | 16 | 2 | 41,299 |
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 Spectrum & Broadcasting: 219 codes on 510,566 documents. The 150 most used are listed; the full list is in the cpc-to-capability.csv download.
