“For nearly two decades, Mars has been studying the process of measuring and maximizing the retention of cocoa flavanols and uncovering their related health benefits, resulting in over 100 scientific publications and a broad patent portfolio,” Mars insisted.

“This suit is consistent with the long-standing commitment at Mars to vigorously enforce its patent portfolio,” the maker of CirkuHealth cocoa flavanol supplements added.

Naturex produces Cocoactiv, Nutraceuticals manufacturs Solaray and Life Extension Foundation prduces Cocoa Gold products, all of which, Mars claims, impede its patent protection rights.
