B24C 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
CPC subclass B24C recorded 15,189 patent applications worldwide between 2013 and 2023. Annual filings grew from 815 in 2013 to 1,250 in 2023 (+53%), peaking at 1,886 applications in 2020. The most active applicants in class B24 are DISCO CORPORATION (2,092 applications), APPLIED MATERIALS (1,813 applications) and EBARA CORPORATION (1,804 applications).
