“When a plaintiff elects literal falsity for a contested claim, often to avoid survey costs, and loses because the claim is not unambiguously false, the structure worked as designed.”
A Lanham Act false advertising verdict is not a scientific meta-analysis. It does not pool evidence, weight studies by quality, or resolve heterogeneity. It allocates burdens and asks whether the party carrying one carried it on the record that party chose to build. Read a false advertising judgment for more than that — for what the science shows, for whether the product works — and you will misread it.
That confusion animates a University of Georgia Law note published this spring, which argues that courts now treat a marketing promise as not literally false so long as the product works for someone, and proposes that any unqualified message failing in practice for ordinary consumers be deemed literally false, Truth That Lies: How Literal Falsity Lost the Consumer and How to Restore It, 33 J. Intell. Prop. L. (2026). The instinct is sound: advertisers do exploit the gap between what a sentence can be defended as meaning and what buyers hear. The diagnosis is not.
What follows is a practitioner’s map of the burdens. If you intend to plead studies, you need to know which of several rules you are about to be judged under.
