The case should go forward, the appeals court said, because the plaintiffs have plausibly alleged that Winfrey was “attempting to build a new segment of her media empire around” the phrase “Own your power.”

She and her company, Harpo Inc., have repeatedly used the phrase, including on a website, for promotional events and on the cover of the October 2010 issues of O, The Oprah Magazine, the court said, adding that Winfrey’s continuous use of the phrase could become “symbolic shorthand” for her products and message as a whole.

Winfrey is one of the most popular talk show hosts in television history and now runs the cable network OWN in a joint venture with Discovery Communications.

Harpo, as well as Hearst Corp., which publishes “O, The Oprah Magazine” and Estée Lauder Cos., are also defendants in the lawsuit.

U.S. District Judge Paul Crotty of New York had dismissed the lawsuit in March 2012, finding that no one seeing the Oprah magazine or information about the related events would think they were created by the plaintiffs, Simone Kelly-Brown and Own Your Power Communications Inc.

The plaintiff also alleged that Winfrey would have known the “Own your power” trademark already existed due to searches that would have been done when her television network, OWN, was developed.

The appeals court agreed it was possible, and those issues will also be reviewed by the lower court.

The court did rule that Winfrey and her co-defendants would not have to face allegations relating to logos used on the magazine or at the events.

In a concurring opinion, Circuit Judge Robert Sack said Friday’s decision should not be interpreted to mean that a publisher is always forbidden from using a trademarked term to describe its content, such as on a magazine cover or in a headline.

In this case, Sack wrote, it was Winfrey’s repeated use of the phrase in an attempt to build an association with consumers that concerned the court.
