International Dairy Queen Inc., owned by Warren Buffett's Berkshire Hathaway Inc., has settled a lawsuit in which it tried to stop a Southern California rival from selling a frozen yogurt with a name similar to its top-selling Blizzard.

Settlement terms were not disclosed, but they allow the defendant, Yogubliz Inc, to continue selling its "Blizz" frozen yogurt, according to Yogubliz lawyer Stephen Abraham.

Dairy Queen had sought to stop Yogubliz from selling Blizz frozen yogurt, saying it could cause confusion among customers with its soft-serve ice cream Blizzard, which is also blended with candy, cookie pieces and other mix-ins.

Yogubliz has stores in the Los Angeles area and Las Vegas.

"Today, Yogubliz is operating Blizz frozen yogurt shops. Tomorrow, it will be operating Blizz frozen yogurt shops," Abraham said in an interview. "Very well-reasoned minds on both sides of the controversy reached a conclusion that accomplishes what they wanted."

David Steinberg, a lawyer for Dairy Queen, did not immediately return a call seeking comment.

The case was dismissed on Monday, according to a filing in Los Angeles federal court.

Dairy Queen has called Blizzard its "most popular and well-known" menu item, with more than $750 million of annual sales. It said it has sold more than 1.5 billion Blizzard treats since 1985.

Yogubliz began operating stores in 2009. The company is based in Downey, California. Dairy Queen is based in Minneapolis, and Berkshire is based in Omaha, Nebraska.
