Yogolove is a popular concept in Brazil: a food chain where you can eat frozen yogurt. Yogolove has a distinctive logo in the shape of a red heart / apple with a green leaf on top.
Yogolove registered its device mark in Brazil. Luckily, because this company is facing a rather unoriginal competitor who probably knows nothing about trademark law. The competitor has filed the trademark Yogolovers. First mistake. The logo is a red heart with a green leaf on top. Second mistake. The only original element is a bite out of the apple. Well, original, where did we see an apple with a bite before?
As a trademark attorney you do not see such obvious cases very often. Neither did the Brazilian Trademark Office who refused the trademark promptly.
