DEFINITION

Classification: 72/362

PROCESS:

(under the class definition) Method, of deformation metal which is not classifiable in any of the subclasses

hereinabove.

(1) Note. Metal-deforming processes claimed in combination with other metal treatments not particularly provided for in this class are generally excluded from this class. However, combinations which comprise a nonsignificant heat treatment and deforming of metal are placed here. See Lines With Other Classes, Relationship to Combination Classes, With HEat Treatment, paragraph 2 of Class 72 definition and Lines With Other Classes, Metal Casting, Metal Fusion Bonding, etc., the first paragraph, of the Class 148 definition to determine what constitutes significant heat treatment for Class 148.

SEE OR SEARCH CLASS

29, Metal Working,

592+, for a process for making a miscellaneous article, that is, one whose manufacture is not the subject of a specific subclass. Except for subclasses 421.1+, these subclasses have not yet been screened and those which do not involve assembly (which are excluded from this Class 72) may contain subject matter similar to that found in this class.

76, Metal Tools and Implements, Making,

101.1+, for a process of making a tool or implement which may include a step of metal deformation, but which also includes another treatment, such as welding or assembly, which latter treatment (or which inclusion of extraneous subject matter) operates to exclude the combination from this class (72). 428, Stock Material or Miscellaneous Articles,

544+, for metallic stock, e.g., of indefinite length, which may be the product of metal deforming operation; and especially subclass 600 of such stock having a variation in thickness.
