Optical coupling means (G02B6/36, G02B6/42 take precedence)

Introduced: January 1985

Title

Titles differ between systems:

IPC: Optical coupling means

CPC: Optical coupling means (G02B6/36, G02B6/42 take precedence)

Full Title

Full titles differ between systems:

IPC:

Light guides; Structural details of arrangements comprising light guides and other optical elements, e.g. couplings > Coupling light guides > Optical coupling means

CPC:

Light guides; Structural details of arrangements comprising light guides and other optical elements, e.g. couplings > Coupling light guides > Optical coupling means (G02B6/36, G02B6/42 take precedence)

Of 9 combined children, 6 exist in both systems.

3 codes are CPC-only extensions.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1985.
