Toy maker Mattel Inc. went to court on Aug. 21 to declare that the name of its clean-cut Barbie dolls doesn’t belong on a model’s pornographic Web site.

In a lawsuit filed in U.S. District Court in Manhattan, Mattel said the Web site for an adult entertainer named China Barbie has tried to benefit from Mattel’s success with the 48-year-old line of dolls, which includes Barbie’s sister, Skipper, her best friend, Midge, and Skipper’s boyfriend, Kevin.
