DEFINITION

Classification: 428/577

(under subclass 544) Subject matter comprising an

intermediate-article*.

(1) Note. If opposite surfaces of an article are defined as converging toward each other at one end, the length of the article is considered definite, for placement in this subclass.

(2) Note. "Recited end structure" means that a structural feature must be pointed out for at least two intersecting thickness surfaces of the article. Where "end" structure is recited without a recitation of "side" structure, the defined "ends" are considered "sides".

(3) Note. See the main definitions of this class (428), section VI, A, 2, for a listing of classes of subject matter which provide for their own blanks.
