Sears is back into court, less than one month after emerging from bankruptcy protection.

The retailer was sued on Wednesday by Stanley Black & Decker, which accused it of breach of contract and trademark infringement over its new line of professional-grade mechanics tools under the Craftsman Ultimate Collection brand.

Sears did not immediately respond to requests for comment. The complaint was filed in Manhattan federal court.

Craftsman had been an iconic Sears brand before Stanley paid about $900 million for it in March 2017, while giving Sears what it called a "limited" license to sell some Craftsman products.

But according to the complaint, Sears breached the license agreement by launching its new tool line and touting its stores as "the real home of the broadest assortment of Craftsman."
