If there is any doubt on whether the essential features of an invention should be classified in this subclass or in the subclasses of class Fulltext... Hierarchy... Expanded...D06, with respect to inventions dealing with processes involving both weaving and finishing steps or with respect to inventions dealing with the finished fabrics, the inventions are classified in class Fulltext... Hierarchy... Expanded...D06 rather than in this subclass.
A method of weaving is classified in the group designating the fabric woven unless the method is characterised by the operation of a particular loom rather than by the production of a particular fabric. In this case, the method is classified in the group for the loom.
In this subclass, for the purpose of classification of inventions, if there is any doubt as to which of the essential features of an invention is the most important (this is usually the most restrictive feature), the groups of this subclass designating woven fabrics should be considered in the order in which they appear at each level of indentation, except that groups designating woven pile fabrics are to be considered as taking precedence over groups designating other woven fabrics.
