Mutual of Omaha and Oprah Battle for "Aha Moment"

Who's really having an "aha" moment? It depends on who you ask. Mutual of Omaha -- the insurance company famous for bringing us Wild Kingdom in the 1970s -- is suing Oprah Winfrey and Harpo Productions Inc. over use of the phrase.

Mutual of Omaha released a statement on Friday saying that it had been grated preliminary approval of a federal trademark for the slogan, official sponsor of the aha moment," which became a part of its national ad campaign in February.

Unfortunately, Oprah is claiming rights to "aha moment." The Queen of All Media told Mutual to stop using the phrase to promote its insurance and financial products. In response, the company filed its lawsuit on Wednesday in U.S. District Court in Omaha.

A Harpo spokesperson says they hope to reach a mutually acceptable resolution with the insurance company.
