The idea for Cliche Check remains up for grabs, presumably due to coders quite liking cliches (after all, repetitive phrases work a lot better in computer code than they do in pleasantly-readable English). However the legal fraternity - much of whose code is written in English - is not resting on this one! A blogger reports that his use of the phrase, "Feel the Fear and Do It Anyway"1, is being contested as copyright violation. The fellow is oddly put out by this - Feeling the Need to Squawk About Free Speech and Doing It Loudly - instead of thanking the phrase's "owner" for helpfully pointing out his hackneyed invocation of a desperately overused linguistic trope, that he might simply coin a new phrase of his own.
He also opens with this image, which I believe is in A Child's First Illustrated Dictionary under "Uncalled-for".
As my stepfather once explained: "Cliches are like sweatpants. Like everyone walking around in sweatpants because they just don't give a fuck". There's no need to get in a tizzy just because Susan Jeffers, Ph.D, asks you to put on nicer pants in public.
