DEFINITION

Classification: 508/202

Organic compound containing silicon (e.g., silicon esters):

(under subclass 110) Compositions which contain silicon in an organic compound component.

(1) Note. An example of a component provided for herein is [figure]

(2) Note. This subclass and its indents provide for organic compound components containing silicon, regardless of the type bonding between silicon and the remainder of the compound.
