CPC Subclass Not Allocatable
B42D BOOKS; BOOK COVERS; LOOSE LEAVES; PRINTED MATTER CHARACTERISED BY IDENTIFICATION OR SECURITY FEATURES; PRINTED MATTER OF SPECIAL FORMAT OR STYLE NOT OTHERWISE PROVIDED FOR; DEVICES FOR USE THEREWITH AND NOT OTHERWISE PROVIDED FOR; MOVABLE-STRIP WRITING OR READING APPARATUS
Description
B42D encompasses books, book covers, and loose-leaf systems with emphasis on security and identification features such as holograms, microprinting, watermarks, and anti-counterfeiting measures. It also covers printed matter of non-standard formats or styles, including specialized devices for handling movable-strip media used in writing or reading applications. This subclass excludes conventional bookbinding methods (covered in B42B) and focuses instead on the distinctive physical or security characteristics that differentiate the printed product itself rather than its binding assembly.
