DEFINITION

Classification: 106/136.1

Cellulosic material:

(under subclass 135.1) Compositions wherein the carbohydrate or derivative is cellulose, a derivative of cellulose, or a naturally occurring material which has cellulose as one of its ingredients.

(1) Note. See this class, subclass 126.2, (3) Note for the

definition of a cellulose.

(2) Note. The term "cellulose derivative" herein is intended to include chemically modified cellulose wherein the carbon skeleton of the cellulose is unchanged or is indeterminate.

(3) Note. This subclass and indented subclasses provide for lignocellulosic material (e.g., wood, bark, etc.), relatively pure cellulose (e.g., cotton linters, etc.), regenerated cellulose (e.g., cellophane and rayon), or chemically modified forms of cellulose (e.g., pyroxylin, viscose, etc.) for which there is no provision elsewhere.
