Aldi accused by Oreo maker Mondelez of copying its packaging

Mondelez International, the company behind Oreo, Wheat Thins and other name-brand products, says Aldi is copying its packaging in an effort to dupe customers into buying the supermarket chain's products.

In a federal lawsuit filed Tuesday in Illinois, the snack company alleges that Aldi "blatantly copies" the distinctive packaging of its brands in order to mislead customers into thinking they are buying a Mondelez product when they are actually purchasing a store-brand version. The company is seeking monetary damages and a court order that would prevent Aldi from selling products Mondelez says infringe on its trademarks.

Neither Aldi nor Mondelez immediately responded to CBS News' requests for comment.
