DEFINITION

Classification: 428/332

(under subclass 221) Product in which the size of an element, constituent, or component of a web or sheet is claimed.

(1) Note. The difference between 212+ and this subclass and indents (332+) is that in the former the thickness of two components* are recited, while in the latter the thickness of only the base or layer is specified. Where the dimensions of two components* are specified so that one can be compared to another, classification in 212+ is indicated.

(2) Note. In this and the indented subclasses a size in units of length must be specified in the claim. A recitation of weight per unit area is excluded from this group of subclasses and will be found in subclasses 340+ below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

212+, for a composite web or sheet in which the thickness of two components is claimed either in terms of their relative thickness or in absolute dimensions.

220, for a product in which the absolute dimension of a web* or sheet* is claimed. 340+, for a recitation of a weight per unit area which can be calculated to yield a physical dimension, if another parameter, such as density, is known.
