Comparative advertising directly compares one's own product or service to that of a competitor. It mentions the competitor by name to show why one's own offering is superior. Comparative claims can explicitly or implicitly highlight similarities or differences between products, assert superiority, or claim equivalence. Comparative advertising is allowed under law if it is honest and truthful, and does not disparage or mislead consumers about competitors' products. However, simply expressing an opinion about a competitor, rather than stating a factual claim, is permitted.
