B43 WRITING OR DRAWING IMPLEMENTS; BUREAU ACCESSORIES
Description
Class B43 encompasses mechanical writing and drawing instruments, including pens, pencils, markers, and related implements for applying marks to surfaces. It covers the design, construction, and functional features of hand-held writing tools, as well as associated office equipment and accessories such as pen holders, inkwells, and desk organization devices. The class includes both traditional implements (fountain pens, ballpoint pens, mechanical pencils) and specialized drawing tools (drafting pens, brush pens, highlighters). Related technologies such as ink delivery systems, nib designs, and writing point constructions fall within this classification, while electronic writing devices and digital input tools are typically excluded.
IPC and CPC are identically structured here. All 3 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
