The Star India v. Leo Burnett case was heard before the Bombay High Court in 2003.
The case revolved around using the TV show Kyunki Saas Bhi Kabhi Bahu Thi as a basis for a Tide detergent commercial and whether this violated copyright law.
[1] Star India was the owner of the copyright in the serial Kyunki Saas Bhi Kabhi Bahu thi's theme and artistic work with which the title appeared on TV according to Clause 6 of the agreement between Star India and Balaji Telefilms.
Producers and Marketers of Tide detergent (the defendants) came up with the advertisement for Procter & Gamble showing a scene resembling climax of the TV show and displaying the artistic work appearing on TV with the words "kyunki bahu bhi kabhi saas banegi" Star alleged that people will think that Star licensed or produced the advertisement.
Further court held that "state of mind of the public" was necessary to see the goodwill of the characters in the TV soap.
