Full Title

Full titles differ between systems:

IPC:

Semiconductor lasers > Arrangement of two or more semiconductor lasers, not provided for in groups

CPC:

Semiconductor lasers (superluminescent diodes H10H20/00) > Arrangement of two or more semiconductor lasers, not provided for in groups H01S5/02 - H01S5/30 (H01S5/50 takes precedence)

CPC subdivides this area 5x more granularly than IPC with 4 additional codes.

4 codes are CPC-only extensions.

IPC defines codes here since 2000.
