Atomberg Technologies Private Limited challenged the Single Judge's order dismissing its interim injunction application against Luker Electric Technologies Private Limited. Atomberg alleged that Luker had fraudulently copied and infringed upon its registered design of the 'Atomberg Renesa Ceiling Fan.' The dispute involved claims of both design infringement and passing off, given the similarity between the products. The Bombay High Court examined the comparison table provided by both parties.
