DEFINITION

Classification: 264/297.1

Forming plural articles:

(under subclass 239) Processes which include forming a plurality of separate and distinct articles either simultaneously or sequentially.

(1) Note. To be placed in this subclass, the articles formed must not be particulate in nature, that is, of such a size that the formed particles can be handled in bulk only. For formation of particulate material from a liquid or molten mass, see the search note below.

(2) Note. The fact that the apparatus used in the process may be capable of continuous operation thus forming plural articles, for example, injection molding devices, is not sufficient to place a patent in this and the indented subclasses. To be placed in this array the patent must claim the process of forming plural articles.
