C09K - Definition fr

Definition statement

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.

References relevant to classification in this subclass
