Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: GRINDING; POLISHING
Subclass:: ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL

Description

B24C covers abrasive blasting processes and equipment using particulate materials to clean, finish, or modify surfaces. This includes sandblasting, shot blasting, grit blasting, and similar techniques where compressed air or mechanical force propels abrasive particles (sand, steel shot, ceramic beads, etc.) against workpieces. The classification encompasses apparatus for directing and controlling the blast stream, containment systems, and related auxiliary equipment, but excludes grinding and polishing operations classified under B24B.

Filing statistics

IPC subclass B24C recorded 33,323 patent applications worldwide between 2013 and 2023. Annual filings grew from 1,463 in 2013 to 4,157 in 2023 (+184%), peaking at 4,683 applications in 2020. The most active applicants in class B24 are DISCO ABRASIVE SYSTEM (3,084 applications), APPLIED MATERIALS (1,570 applications) and EBARA CORPORATION (1,393 applications).
