The following IPC groups are not used in the CPC system. Subject matter covered by these groups is classified in the following CPC groups:
F21K5/04 covered by G03B 15/0457 F21K5/06 " " G03B 15/0442 F21K5/08 " " F21K 5/02 , G03B 15/0442 F21K5/10 " " G03B 15/0442 F21K5/12 " " F21K 5/023 F21K5/14 " " F21K 5/026 , G03B 15/0489 F21K5/16 " " G03B 15/0452 F21K5/18 " " G03B 15/0452 F21K5/20 " " G03B 15/0447 F21K5/22 " " G03B 15/0442

Groups F21K 9/00 to F21K 9/90 do not correspond to former or current IPC groups.
Concordance CPC : IPC for these groups is as follows:
- F21K 9/00 to F21K 9/90 : F21K 99/00
