The indexing codes under E05Y 2201/20 are used to classify further details not available in the main trunk. In particular, the indexing codes as foreseen under E05Y 2201/21 and E05Y 2201/224 are used to classify braking devices, stops or buffers combined with motors associated with wings.
The indexing codes under E05Y 2201/21 and E05Y 2201/224 are however not applied when classification symbols in E05F 5/00 or subgroups are being allocated for inventive information.
Looping references between E05F 5/00 and E05F 3/00 have been identified. Until this inconsistency is resolved in IPC, the current classification practice in CPC is as follows: Reference E05F 3/00 is limiting in the subgroup E05F 5/00. CPC will be corrected once this inconsistency is resolved in IPC.
