Calcutta High Court · AIR1979CAL238

This Calcutta High Court judgment addresses an appeal against the refusal to register a trade mark for 'Keora water.' The core dispute revolved around whether the proposed mark was deceptively similar or conflicted with existing registered marks held by the opponent. While the appellant argued that the Deputy Registrar erred in his assessment of similarity, the court ultimately upheld the registrar's decision. The judgment reinforces established principles regarding consumer perception and the necessity of considering the 'whole picture' when determining trade mark confusion.

Raytheon Company v.The Controller Of Patents And Designs

Calcutta High Court

Raytheon Company appealed the refusal of its patent application (No. 133687) for an 'Imaging System'. The refusal was based on the opinion of the Central Government, which held that the invention related to atomic energy and thus could not be patented under Section 20 of the Atomic Energy Act, 1962. The High Court dismissed the appeal, holding that the direction of the Central Government is final and beyond challenge in an appeal under the Patents Act.
