Advocate Hiren Kamod, appearing for Abbott, argued that since the 1960s, the company had been openly, continuously and extensively using the 'Dupha' marks in respect of medicinal and pharmaceutical preparations and had achieved sales of hundreds of crores of rupees.Also read: Abbott signs pact with Novo Nordisk to offer semaglutideCountering this, Menschlich Healthcare argued that Abbott Product did not have registration of the standalone mark 'Dupha', nor had it ever been assigned or transferred to the petitioner company.The respondent company also argued that the petition was nothing but an attempt by the petitioner to secure a monopoly over 'Dupha', irrespective of the well-settled principles governing trade mark law.
