Class 101

PRINTING


Class Definition:
Means not otherwise provided for adapted to produce characters or designs on surfaces by impression of types or dies or by applying coating material thereto through openings of previous portions of a pattern sheet, as in stenciling, or by impression from planos:graphic or intaglio surfaces.
(1) Note. Includes organizations using design or character dies that emboss, burn, or perforate, as well as those that are intended to apply ink.

LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
For means and methods for making type or other bodies having printing surfaces see Class 76, Metal Tools and Implements, Making; Class 156, Adhesive Bonding and Miscellaneous Chemical Manufacture; Class 164, Metal Founding; Class 178, Telegraphy; Class 199, Type Casting; Class 204, Chemistry: Electrical and Wave Energy; Class 205, Electrolysis: Processes, Compositions Used Therein and Methods of Preparing the Compositions; Class 264, Plastic and Nonmetallic Article Shaping or Treating; Processes; Class 425, Plastic Article or Earthenware Shaping or Treating: Apparatus; and Class 430, Radiation Imagery Chemistry: Process, Composition, or Product Thereof.
Patents containing product claims originally classified in Class 101, Printing, subclasses 128.21 through 129, 450.1 through 473, 211, 295, 401.1 through 401.6 involving significant claimed chemical subject matter and no significant structure or printing steps are being reclassified into the appropriate chemical product or material class. Notes under the pertinent above indicated subclasses indicate the extent and scope of this work as of August 1969.
Where a printing plate of the planos:graphic type or a stencil element, i.e., stencils and blanks, is claimed with no significant printing plate or stencil element structure or printing steps but merely in terms of the composition or material of which at least one of its layers is composed, it will be classified in the appropriate product or composition class, even though there is no claim to the composition, per se.
The line between Class 83, Cutting, and Class 101, Printing, subclasses 3.1+ is as follows:
The mere removal of portions of sheet material interposed between one or more punch and die sets, whether or not the aperture or series of apertures produced form characters or designs which convey intelligence, has been considered punching for Class 83. However, where more than the mere removal of material is involved and additional apparatus or steps add to enhance the character or design produced, (e.g., the application of ink to the punches to additionally mark or outline the apertures), such additions have been considered printing for Class 101, subclass 3.1.
Deforming of sheet material into characters or designs with or without the removal of any portion of the material has been considered printing for Class 101, subclasses 3.1+.
