Levi Strauss has a number of copyright lawsuits out right now, including several against Japanese brands and even more against big American labels, including Guess, Rock & Republic, and Lucky. Today they add Polo Ralph Lauren to that list, accusing the lifestyle giant of ripping off their patented pockets. According to WWD, the brand feels that anytime their pocket stitch - that bendy "V" that stretches across the butt - is copied, it counts as a lawsuit. But the International Herald Tribune has been on this story since January, and their reporting subtley questions whether Levi Strauss actually feels violated, or whether the company simply has the resources to keep competitors in court for years. Meanwhile, here's what we wondered: Are enough people still buying Levis that the brand thinks it's being copied? Wouldn't Habitual and Paper worry more about their pocket design, since those jeans are actually in demand? Or should we back off in case we're somehow sued, too?
