(under subclass 402) Product in which at least a portion of a web or sheet, or in which a constituent strand* or sewing thread incorporated in a web or sheet, possesses a relatively high degree of extensibility or deformability longitudinally and/or transversely of the web or sheet and the ability to resile from such extension or deformation with substantially no permanent deformation.
(1) Note. Patents including a layer which is elastically compressible in the direction of web thickness only are excluded from this subclass, as indicated by the term "longitudinally and/or transversely" in the definition.
