The Delhi High Court on Tuesday issued summons to Patanjali Ayurved Ltd. on a petition by Dabur India Ltd. alleging that Patanjali Ayurved, through television commercials relating to its Chyawanprash products, was disparaging the petitioner and defaming its products. The court also issued a notice to Patanjali Ayurved on Dabur India's plea to seek an interim injunction against running of the commercial. The court will hear the case next on Jan. 30.
