German sporting goods giant Adidas is suing to protect its trademark three-stripe logo, arguing that Abercrombie & Fitch Co. copied the design for its latest line of casual wear apparel featured in an online Christmas catalog.

The offending merchandise includes several pairs of pants and a zip-up sweatshirt, all adorned with three parallel stripes running down the sleeve and pant leg, according to a lawsuit filed in U.S. District Court in Portland, Ore.
