NEW YORK (AP) — J.C. Penney's woes keep piling on. In the latest string of troubles, Macy's won a preliminary injunction against Martha Stewart Living that would prevent it from selling some of its products at the chain.

The decision from New York State Supreme Court Justice Jeffrey Oing on Friday is a setback for J.C. Penney, which has been counting on the popularity of the Martha Stewart brand as part of its efforts to help revitalize its business under new CEO Ron Johnson.

Macy's Inc. sued Martha Stewart Living in January, saying that it had exclusive rights to certain categories of the brand until 2018. The complaint was filed after J.C. Penney acquired a 16.6 percent stake in Martha Stewart Living and announced plans in December to open Martha Stewart mini-shops beginning next year.

So far, the transformation hasn't been going well, as a new pricing plan that eliminates hundreds of sales events in favor of everyday pricing has turned off shoppers. That's resulted in a bigger-than-expected drop and a 20 percent revenue decline in the quarter that the pricing plan was implemented. As a way to draw shoppers in the stores, the company has signed up new brands like Vivienne Tam and Betsey Johnson, but its biggest coup was signing the Martha Stewart brand.

"We expect to continue to exclusively sell Martha Stewart-branded merchandise in categories such as cookware, kitchen utensils, bed and bath for the term of our contract," said Jim Sluzewski, a spokesman at Macy's in a statement emailed to The Associated Press.

However, Martha Stewart Living Omnimedia Inc. plans to move forward with sales of its products for J.C. Penney starting next year, said spokeswoman Jeanne Meyer.

"Nothing about today's ruling changes that," said Meyer. "We will comply with whatever restrictions are placed upon us at this time."

She emphasized that the ruling was preliminary and that the company will "continue to defend our legal and commercial position."

"We continue to believe we have not breached our agreement and that extending our brand to a wide array of retailers is beneficial to all our partners," Meyer said.

J.C. Penney declined comment.

Following a verbal ruling Friday, a formal injunction is expected to be filed by the end of next week, according to Sluzewski.

J.C. Penney is based in Plano, Texas. Macy's is based in Cincinnati.

Penney's shares slipped 2 cents to close at $20.02, while Macy's shares rose more than 2 percent, or 81 cents to $33.64. Martha Stewart Living's shares rose 1 cent to $3.53 per share.
