SECTION I - CLASS DEFINITION

This class includes:

(A) Products containing tobacco or tobacco substitutes intended for personal use for smoking or chewing or for use as snuff.

(B) Processes and apparatus for manufacturing the products set forth in paragraph (1) where not elsewhere provided for.

(C) Processes and apparatus for treating tobacco preliminary or subsequent to manufacturing into products of paragraph (1) where not elsewhere provided for.

(D) Appliances peculiarly adapted to use by smokers where not elsewhere provided for.

SECTION II - NOTES TO THE CLASS DEFINITION

(1) Note. The word "tobacco", as used in this class, is considered generic to any material which may be smoked or may be substituted for real tobacco.
(2) Note. Tobacco product manufacturing apparatus may be claimed in combination with apparatus of another classified art. When such is the case, the combination will be found with the other classified art, if the tobacco product manufacturing apparatus is in name only, or no more of the apparatus is claimed than is necessary to support the operation of the other classified art device.
