The Durex Products Ii:tc., of New York City, U. S. A. made an application before the Deputy Registrar of Trade Marks on May 28, 1946 for registering the mark "Durex" used by ii on "contraceptive devices including prophylactic sheaths or condrums, vaginal diaphragms, instruments for inserting diaphragms and models for demonstrating insertion of diaphragms, vaginal jellies, applicators for vaginal jellies and surgical lubricating jellies." Its claim is disputed by the London Rubber Co., Ltd., London, the appellant before us by lodging an opposition to the registration on March 29, 1951. The appellant claims to be well-established manufacturer of surgical rubber goods and proprietor in India of the trade mark "Durex" which it has been using in India since the year 1932 i. e., from the year in which it was registered in the United Kingdom. On December 23, 1946 the appellant applied for registration of the word "Durex" in "clause X" which application was granted on July 11, 1951. Thereafter, on July 24, 1954 the registration was renewed for a period of 15 years as from December 23, 1953. The respondent No. l's application as well as the appellant's opposition came up before the Deputy Registrar of Trade Marks who, by order dated December 31, 1954, overruled the objection and admitted the mark "Durex" to registration as sought by the respondent No. I. Against this order an appeal was preferred before the High Court of Calcutta under s. 76 of the Trade Marks Act, 194.1 which was dismissed by a Division Bench of that Court on March 9, 1959,
