Conflicting Marks

Case reference

SUPER CHIRO TEA for "herbal teas for medicinal purposes" so resembled opposer's previously used mark CHIROKLENZ for a detoxifying herbal tea, as to be likely to cause confusion among purchasers.

The Board found that applicant took "affirmative steps to cause confusion and to associate SUPER CHIRO TEA with CHIRO-KLENZ tea." These affirmative steps included using the URL www.chiroklenzforless.com and using confusingly similar trade dress.

Edom Laboratories, Inc. V. Lichter (TTAB 2012)

L'OREAL PARIS for "aloe vera drinks" so resembles opposer's previously used and/or registered L'OREAL and L'OREAL PARIS marks for a full range of cosmetics, skin care, and hair care products, some that include aloe vera as an ingredient, as well as for a variety of services, as to be likely to cause confusion.

L'OREAL S.A. v. MARCON, (TTAB 2011)

 GULPY, when used in connection with "portable animal water dishes and animal water containers sold empty" does not so resemble BIG GULP, GULP, or any of opposer's other "Gulp" marks as to be likely to cause confusion, to cause mistake, or to deceive.

7-Eleven v. Wechsler, (TTAB 2007)

OIL ZONE and WASH ZONE (junior marks) for oil change and car wash services are sufficiently similar to (senior user) AUTOZONE mark for retail auto parts sales:

  • All marks have two words, with “Zone” as second word;
  • Words in marks are in same font and are slanted in same direction;
  • First letter of both words is larger than other letters in all marks;
  • All marks feature bar designs that suggest movement or speed.

Marks must be viewed in their entireties, and despite certain dissimilarities, prominent similarities between marks may lead consumers to believe that OIL ZONE and WASH ZONE were extensions of AUTO ZONE.

AutoZone Inc. v. Strick, 88 USPQ2d 1225 (7th Cir. 2008)


“Girl Design” senior mark for U.S. parboiled rice sold in Saudi Arabia was infringed by “Girl with a Hat Design” used on bags of U.S. parboiled rice sold in Saudi Arabia, even though senior user’s design depicts visibly Asian girl, whereas junior user’s design incorporates scarf or hat on girl's head, since marks both depict young women with similar hair, dress, and features, posed behind rectangular shape, holding bowl of rice, and utilize same red, yellow, and black color scheme.

Findings: the Lanham Act requirements were met such that ARI's Girl Design was protectable because the image of a girl icon being used to sell rice is not intrinsic to rice as a product

American Rice Inc. v. Producers Rice Mill Inc., 86 USPQ2d 1162 (5th Cir. 2008).


In assessing likelihood of confusion marks at issue, marks must be compared in their entireties. CHI PLUS mark for electric massage apparatus is likely to cause consumer confusion with CHI design mark for legally identical goods, since word “Chi” is integral component of parties' marks, and addition of word “plus” to mark already established and in use for electric therapeutic massagers is likely to cause confusion, mistake, or deception. In this case, other differences between parties' marks are unlikely to prevent confusion.
