Mighty Leaf Tea not so mighty at CAFC

Mighty Leaf Tea tried to register the mark ML, in standard character form but Mark Lees had already registered ML in stylized form (shown in the decision). Judge Newman upheld the TTAB decision against Mighty Leaf Tea, after a review of the DuPont factors [ In re E.I. DuPont De Nemours & Co., 476 F.2d 1357, 1361 (CCPA 1973) ].
