CPC:

Cleaning or keeping clear the surface of open water; Apparatus therefor (construction of ships or other waterborne vessels B63B, e.g. vessels specially adapted for collecting pollution from open water B63B35/32; in swimming or splash baths or pools E04H4/16) > Devices for cleaning or keeping clear the surface of open water from oil or like floating materials by separating or removing these materials (; other treatment of water, waste water or sewage C02F; materials for treating liquid pollutants, e.g. oil, gasoline, fat, C09K3/32 )

CPC subdivides this area 3x more granularly than IPC with 6 additional codes.

6 codes are CPC-only extensions.
