characterised by their crystalline properties, e.g. semi-crystalline (catalysts comprising carbon B01J21/18; molecular sieves B01J29/00)

Introduced: January 2024

Title

Titles differ between systems:

IPC: characterised by their crystalline properties, e.g. semi-crystalline

CPC: characterised by their crystalline properties, e.g. semi-crystalline (catalysts comprising carbon B01J21/18; molecular sieves B01J29/00)

Full Title

Full titles differ between systems:

IPC:

Catalysts, in general, characterised by their form or physical properties > characterised by their crystalline properties, e.g. semi-crystalline

CPC:

Catalysts, in general, characterised by their form or physical properties > characterised by their crystalline properties, e.g. semi-crystalline (catalysts comprising carbon B01J21/18; molecular sieves B01J29/00)

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

3 codes are CPC-only extensions.

IPC defines codes here since 2024.
