B05C APPARATUS FOR APPLYING FLUENT MATERIALS TO SURFACES, IN GENERAL (spraying apparatus, atomising apparatus, nozzles B05B; plant for applying liquids or other fluent materials to objects by electrostatic spraying B05B5/08)
Description
Covers apparatus and devices for applying liquid, semi-liquid, or flowable materials uniformly to surfaces by means other than spraying or atomising. This subclass includes brushes, rollers, squeegees, immersion coating systems, and curtain-coating equipment used for paints, varnishes, adhesives, inks, and similar fluent materials in industrial and commercial applications. Excludes spraying and atomising devices, which are classified under B05B, and surface preparation or finishing processes that do not involve material application.
Filing statistics
CPC subclass B05C recorded 59,555 patent applications worldwide between 2013 and 2023. Annual filings grew from 3,563 in 2013 to 5,946 in 2023 (+67%), peaking at 7,264 applications in 2020. The most active applicants in class B05 are 3M INNOVATIVE PROPERTIES COMPANY (MINNESOTA MINING AND MANUFACTURING INNOVATIVE PROPERTIES COMPANY) (1,265 applications), DUERR SYSTEMS (1,191 applications) and TOKYO ELECTRON (1,157 applications).
