Can I use or register "DEF"?

For the same or related goods, probably not. In class 1 (chemicals), class 4 (fuels, oils and candles) and class 35 (advertising, business and retail), a new application for an identical or confusingly similar name is likely to be objected to by the Registry under Section 11 of the Trade Marks Act, 1999, or opposed by the earlier applicant. Closely related classes, such as class 5 (pharmaceuticals and health), class 31 (fresh produce and agriculture), class 37 (construction, installation and repair) and class 29 (meat, dairy and processed food), carry the same risk.

For unrelated goods, often yes. The same word can be registered by different owners in different classes when the goods are unrelated and the earlier mark is not well known. "DEF" appears in 3 classes; the other 42 may still be open, subject to a search.

A small change rarely helps. Adding a word, changing a letter or using a logo does not avoid conflict on its own: marks are compared as a whole, by look, sound and idea. We already see 5 similar names in the same classes (below).

Questions about DEF

What does "advertised" mean? Read trademark status meanings, how long registration takes and how to run a trademark search.

Source and limits. Built from the Trade Marks Journal published by the Registrar of Trade Marks (a public record), issues from August 2021 onwards, as advertised and subject to transcription errors. The journal shows that an application was accepted and advertised; it does not show what happened afterwards (registration, opposition, withdrawal or abandonment), applications not yet advertised, or marks advertised before August 2021, so this is not the live register status. Applicants may ask for a correction or removal by writing to mehak@trademarkindia.pro. Information only, not legal advice and not a solicitation.
