.~> Wood timber product (e.g., piling, post, veneer, etc.)
(under the class definition) Product comprising a block* or other solid mass*, or a single layer*, sheet* or web* which is found in nature in substantially the same form and is saturated or permeated with an extraneous material substantially throughout.
(1) Note. If recited to specify a specific depth of penetration of the saturating material so that a definite interface can be determined, classification is above this subclass on other features such as for example 212+ or 411.1+.
(2) Note. Where no specifically recited depth of penetration is recited as for example, 1/4 inch, half-way through, etc., the product will be considered to be impregnated substantially throughout and will be placed in this subclass.
(3) Note. Where a claim includes a solid block or piece of wood, and alternatively wood pulp or wood flour or wood chips and no structure of the particles, the original classification will be in this or the indented subclass with a cross reference to the appropriate composition or other classes, e.g., 106, 162, 252, 260, etc.
(4) Note. Unless disclosed otherwise, wood and leather will be considered as in the solid-state and proper for this or the indented subclass.
(5) Note. Rubber is not a natural solid and is excluded from this group of subclasses. (6) Note. Unless otherwise described or identified (as for example as particles*, chips, etc.) cork will be considered to be a natural solid and will be classified in subclass 541 indented hereunder.
