Sportswear maker Lite Breeze Inc is suing pop star Britney Spears and three other defendants for $10 million dollars over trademark infringement claims.

The San Diego-based company, which produces clothing under the In The Zone label, alleged Spears had infringed its US trademark by releasing a CD bearing the same name.

According to company president Rodd Garner, Lite Breeze has held the licence to the In The Zone trademark for more than 12 years.

"In The Zone is as wholesome and all-American as hotdogs and apple pie," Garner said.

"By releasing her CD entitled 'In The Zone' and its promotional tour, now entitled 'The Onyx Hotel Tour', Ms Spears has taken Lite Breeze's brand and equated it with what Rolling Stone Magazine has stated 'offers strip-club, 1-900 sex, accommodating and hollow'."

Despite the lawsuit being filed in February, Spears did not accept service of the legal papers until May.

She and the other defendants, including broadcaster Clear Channel Entertainment Televison Holdings Inc, entertainment properties licensor Signatures Network Inc and record label Zomba Recording Corp, now have until June 14 to file their answers to the allegations.
