B41P INDEXING SCHEME RELATING TO PRINTING, LINING MACHINES, TYPEWRITERS, AND TO STAMPS
Description
B41P serves as an indexing or residual classification for technologies related to printing, lining machines, typewriters, and stamps that do not fit neatly into the more specific subclasses within the B41 group. This class captures miscellaneous mechanical and electromechanical devices used in printing production, document preparation, and stamping applications. It functions as a catch-all category for innovations or prior art that fall outside the defined scope of established B41 subdivisions, ensuring comprehensive coverage of the broader printing and typing technology domain.
Of 11 combined children, 0 exist in both systems.
11 codes are CPC-only extensions.
Note: 11 CPC extensions are marked as secondary classification only.
