The Board affirmed a refusal to register the color
"copper" for "flexible, plastic tubes used in
subsurface drip irrigation systems," finding the proposed mark
to be aesthetically functional under Section 2(e)(5). Moreover,
assuming that the color "copper" is not functional for
the goods, the Board found that the proposed mark lacked acquired
distinctiveness under Section 2(f). In re Rain Bird Corporation, Serial
No. 85044106 (January 3, 2019) [not precedential] (Opinion by Judge
Robert H. Coggins).

Functionality: The Board observed that a color
may be a source indicator (e.g., the green-gold dry cleaning press
pads in Qualitex and the pink fiberglass insulation of
Owens-Corning), or it can be functional (e.g., the black
outboard motors in Brunswick and the black boxes for
floral arrangements in Florists' Transworld
(FTD)). [Or it can be neither - ed.].
