Just as the song Pungi... from Saif Ali Khan's spy thriller 'Agent Vinod' is gaining popularity, an Iranian music band has slapped a legal notice on music director Pritam Chakraborty and distributors for alleged copyright violation

The music band Barobax Corp was founded in 2003 by three Iranian nationals Kashayar Haghgoo, Kevian Haghgoo and Hamid Farouzmand. According to the legal notice issued by law firm Vidhii Partners, Barobax had on January 16, 2010 produced and released an album titled 'Soosan Khanoom' which became a rage.

"On March 12 this year, the band came across the promotions of the movie 'Agent Vinod' on satellite television in Iran. The song Pungi... was being aired. On listening to the song, the band realised that the initial portion of the song is lifted without any change from the title song of their album," the notice claims.

According to the notice, the band is the owner of the copyright of the song 'Soosan Khanoom' which is registered under the Copyright Act in Canada on June 30 last year and hence the music of the song cannot be used without the band's permission.

Soon after learning about the copyright infringement the band sent their representative Nargis Kazerooni to India to initiate legal action.

Apart from music director Pritam, the notice has also been served to Eros International Media, Illuminati Films Private Ltd and Super Cassettes Ltd.

"We demand the music director, producers and directors to refrain from releasing the song in the movie or use it to promote the movie. Failing to do so, the band shall be compelled to initiate proceedings to seek a restraining order and necessary compensation," the notice states.

The movie starring Saif Ali Khan and Kareena Kapoor is slated for release on March 23.
