DEFINITION

Classification: 507/104

Organic component is cellular or fibrous material derived from plant or animal source (e.g., wood, nutshell, paper, leather, cotton, etc.):

(under subclass 103) Composition which contains a cellular or fibrous material derived from a plant or animal source, such as wood, nutshell, seed, cotton, paper, leather, hair, etc.

(1) Note. Cellular material includes naturally occurring material which still retains a certain amount of the original tissue structure of the plant or animal.

(2) Note. Grinding, pulverizing, and comminuting does not result in the loss of original tissue structure of such material, whereas extracting generally results in the loss of original tissue structure in at least one of the products (i.e., the product being extracted). In an extraction, however, some original tissue structure may not be destroyed,

i.e., the material from which a product is being extracted may retain structure.

(3) Note. Fossilized materials are not included in this subclass.
