DEFINITION

Classification: 75/231

Molybdenum sulfide or functional constituent, (e.g., lubricant, abrasive, etc.):

(under subclass 230) Composition in which the nonmetal is a molybdenum sulfide or in which a solid, nonmetal component is claimed in functional terms, such as a lubricant, an abrasive, a frictional component, etc.

(1) Note. Where the functional component is restricted to a specific material other than MoSx, the patent is classified in the "nonfunctional" subclass below, appropriate to the material, e.g., diamond as the sole permissible abrasive or graphite as the sole permissible lubricant, are provided for in subclass 243, etc., and is cross-referenced here (subclass 231) if appropriate.

(2) Note. Where the description of the functional component is of hybrid character, the patent is classified in this subclass only when the component is not specifically provided for below, e.g., an "abrasive oxide" is provided for in subclasses 232+, but a "lubricating sulfide" indicates classification in this subclass (231).
