| | Class 101: PRINTING / U.S. Patent Classification Definitions |
 | | 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. |
 | | 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. |
 | | See the class definition, lines with other classes and within this class for the line between this class (101) and the Cutting class. |
