The USPTO refused registration of the mark SNAP
FUNNEL for funnels [FUNNEL disclaimed], finding the mark
likely to cause confusion with the registered mark SNAP
& POUR for a "funnel which snaps onto plastic
containers, including automotive fluids and household cleaners and
detergents." The goods overlap, but what about the marks?
Isn't SNAP & POUR rather weak? How do you think this came
out? In re Gabor Alex Stibinger, Serial No.
87144063 (December 4, 2018) (Opinion by Judge Thomas W. Wellington)
[not precedential].

The Goods: Applicant's "funnels"
encompass registrant's snap-on funnels, and so the involved
goods are legally identical. Consequently, it is presumed that
these overlapping goods travel in the same trade channels to the
same classes of consumers. These factors weighed
"heavily" in favor of a finding of likely confusion.
