E06B FIXED OR MOVABLE CLOSURES FOR OPENINGS IN BUILDINGS, VEHICLES, FENCES OR LIKE ENCLOSURES IN GENERAL, e.g. DOORS, WINDOWS, BLINDS, GATES (shades or blinds for greenhouses A01G9/22; curtains A47H; lids for car boots or bonnets B62D25/10; skylights E04B7/18; sunshades, awnings E04F10/00)
Description
E06B covers the design and construction of closures for openings in buildings, vehicles, fences, and comparable structures, including doors, windows, blinds, gates, and related hardware. This subclass encompasses both fixed installations (e.g., fixed windows, stationary panels) and movable closures (e.g., hinged doors, sliding windows, roller blinds, swing gates), as well as their structural components and operating mechanisms. The classification includes general closure systems and assemblies that do not fall under more specialized subclasses dedicated to specific closure types or technical features (such as emergency exits or specialized sealing systems). Adjacent subclasses (E06C, E06D) address more particular technical aspects like closures with special heating/cooling functions or specific movable door and window mechanisms.
Filing statistics
CPC subclass E06B recorded 94,488 patent applications worldwide between 2013 and 2023. Annual filings declined from 6,576 in 2013 to 6,204 in 2023 (-6%), peaking at 11,587 applications in 2018. The most active applicants in class E06 are SAINT-GOBAIN GLASS (1,388 applications), HUNTER DOUGLAS (874 applications) and VIEW (763 applications).
