Full titles differ between systems:
IPC:
Coupling devices of the waveguide type > Coupling devices having more than two ports > Conjugate devices, i.e. devices having at least one port decoupled from one other port > of the junction type > Hybrid ring junctions
CPC:
Coupling devices of the waveguide type > Coupling devices having more than two ports (H01P5/04 takes precedence) > Conjugate devices, i.e. devices having at least one port decoupled from one other port > of the junction type > Hybrid ring junctions
Of 3 combined children, 0 exist in both systems.
