DEFINITION

Classification: 264/340

(under the class definition) Processes in which preformed, shaped, or solid articles are subjected to a treatment.

(1) Note. Treatment, for the purpose of this and indented subclasses, included all procedures in which the chemical or physical properties or characteristics of a work piece are modified or controlled by other than mechanically shaping by contacting the work with a solid shaping member.

(2) Note. Subsequent treatment, per se, of an article, which involves a chemical reaction with said article, in the

absence of a particular manipulative or handling step, or specific shape retaining or supporting step not otherwise classifiable above, is not sufficient to bring a patent herein. See the line between the composition classes and this class as set out in the definitions above.

(3) Note. To complete the search for processes of treating the appropriate subclasses set out above which include combinations of shaping and treating should be searched.
