Hyderabad: Dr Reddy’s Laboratories, which is embroiled in a legal battle with AstraZeneca over the usage of purple colour for generic version of Nexium, has filed a complaint in a US court alleging that the latter “knew” about its plans to use the same colour in the capsules.
This comes days after the Indian firm was temporarily restrained by a US court from using purple colour for its generic version of Esomeprazole in US market.
