In the notice, Zee has contended that Star's serial Betiyaan, to be launched next month, has ‘striking' similarities with its own proposed television soap Ghar Ki Lakshmi—Betiyaan.
The Subhash Chandra group firm also asked Star to "remove and destroy" all advertisement, hoarding and other materials to promote its soap.
"Our right is highly valuable to us as we have invested a lot of resources in the programme to build awareness and goodwill," it said.
Zee also contended it had the copyright on the programme, which is being produced by Creative Eye Ltd and use of similar concept or contents would amount to violation of intellectual property laws.
"We trust that with your good reputation in the industry, you will not force us to take the matter to appropriate authorities, including injunctive reliefs and damages," the Zee notice said.
The company said it started the promos of Ghar Ki Lakshmi—Betiyaan in August. The programme is registered with Film Writers Association and Films and Television Producers Guild of India Ltd.
"It has also been registered with Society for Copyright Regulation of Indian Producers for Films and Television (SCRIPT) has been confirmed by Association of Motion Pictures and TV Program Producers," Zee Vice President Sanjay Jain contended in the notice.
