Registrability of trademarks derived from generic names in Pharma Industry - Madras High Court analyses and propounds test to strike a balance

By Vindhya S Mani, Mohit Kar and Kriti Sood

The article in this issue of IPR Amicus discusses a recent Madras High Court decision against a refusal order for registration of the mark ‘Inimox’ considering an opposition by the owner of mark ‘Imox’, both used for pharmaceuticals. The High Court has overturned the Registry’s findings in respect of ‘likelihood of confusion’ and allowed the appeal, directing the mark ‘Inimox’ to proceed towards registration. Elaborately discussing the rival contentions before the Court and the Court’s decision, the authors note that the said decision has provided clarity on the contours of registering API-derivate brand names in the pharmaceutical industry, and the necessary due diligence that needs to be carried out in that regard. They also observe that trademarks that are arbitrary or inventive carry more weight, and that a mark’s uniqueness is automatically diminished when it is derived from a generic name, API or disease/condition’s name.
