C09K - Definition
This subclass covers:
The use of materials for applications not provided for elsewhere, e.g. sealing materials, drilling fluids.
The use of materials in general having specific properties, not provided for elsewhere, e.g. anti-static properties, anti-oxidation properties.
Materials selected for uses or applications not provided for elsewhere.
All entries in this subclass relate to specific properties (e.g. C09K 3/16 relates to materials with anti-static properties) or specific applications of materials (e.g. C09K 17/00 relates to soil-conditioning or soil-stabilizing materials), except for main group C09K 3/00 itself, which is the residual place for classifying materials with properties or applications for which no entries exist in C09K itself nor elsewhere in IPC.
