High Court of Delhi (Jyoti Singh, J., oral) — Rectification/cancellation petition under Sections 47 and 57 of the Trade Marks Act, 1999 by ACKO Technology and Services Pvt. Ltd. (registered proprietor of the well-known mark ACKO, user since 2016, registered 01.12.2017 in Classes 38 and 42) seeking removal of Respondent No.1's mark 'ACCKO' (Regn. No. 3713450, Class 09, 'mobile and accessories'; applied 28.12.2017 on proposed-to-be-used basis). Respondent No.1 was set ex parte (order dated 09.04.2025) and filed no reply. Held: (i) Petitioner is a 'person aggrieved'; (ii) absent any specific denial, non-use of the impugned mark is deemed admitted and, no special circumstances having been shown, the mark is liable to be removed under Section 47(1)(b); (iii) 'ACCKO' is phonetically and visually deceptively similar to 'ACKO', the added letter 'C' being insufficient, and with overlapping services confusion is inevitable, so the registration is hit by Section 11(2); (iv) adoption of the mark was a 'textbook case' of bad faith to encash on the Petitioner's goodwill, fortified by the respondent's uncontested stance; continuation on the Register is contrary to Sections 47(1)(b) and 57 and prejudicial to public interest and the purity of the Register. Petition allowed; registration of 'ACCKO' cancelled; Registrar of Trade Marks directed to remove the mark and rectify the Register within two months.
