Full titles differ between systems:
IPC:
Preparation of hydrocarbons from one or more compounds, none of them being a hydrocarbon > from oxides of carbon > from carbon monoxide with hydrogen
CPC:
Preparation of hydrocarbons from one or more compounds, none of them being a hydrocarbon > from oxides of a carbon (preparation of liquid hydrocarbon mixtures of undefined composition C10G2/00; of synthetic natural gas C10L3/06) > from carbon monoxide with hydrogen
CPC subdivides this area 4x more granularly than IPC with 5 additional codes.
5 codes are CPC-only extensions.
