Description

B23D covers machine tools and metal-working operations that remove material through planing, slotting, shearing, broaching, sawing, filing, scraping, and similar processes not specifically classified elsewhere. This subclass includes the machines, tools, and techniques for these cutting and abrading operations on metal workpieces, encompassing both manual and powered equipment. It serves as a residual classification for metal removal operations that do not fall under more specialized subclasses (such as grinding, drilling, or turning). Adjacent classes like B23B (turning) and B23H (other metal-working processes) handle alternative removal methods with different cutting geometries or principles.

Filing statistics

IPC subclass B23D recorded 132,167 patent applications worldwide between 2013 and 2023. Annual filings grew from 5,271 in 2013 to 17,326 in 2023 (+229%), peaking at 20,095 applications in 2020. The most active applicants in class B23 are ITW (ILLINOIS TOOL WORKS) (3,407 applications), FANUC (3,120 applications) and DISCO ABRASIVE SYSTEM (2,777 applications).
