DEFINITION

Classification: 428/456

(under subclass 455) Product in which the cork is admixed with (natural oil, natural gum or rosin*).

(1) Note. Linoleum usually is a composition comprising cork and linseed oil. Unless it is clear than the term is distorted in a patent, the word linoleum, in the description of a laminate or layer thereof, will be sufficient to place a patent to such laminate in this subclass. An obvious distortion would be the use of the word linoleum for vinyl floor covering.

SEE OR SEARCH THIS CLASS, SUBCLASS:

500+, for a vinyl containing laminate which is similar to linoleum; and see (1) Note above.
