The Bombay High Court has cancelled Thane-based Menschlich Healthcare's trademark 'Duphachrit' in favour of Abbott Product Operations AG. The court found the mark deceptively similar to Abbott's 'Dupha' family of brands, including Duphaston and Duphalac, which have been in use since 1951. Justice Arif Doctor ruled that Menschlich's adoption of the mark was dishonest and intended to capitalize on Abbott's established reputation and goodwill.
