Can I use or register "DIADEM"?
For the same or related goods, probably not. In class 5 (pharmaceuticals and health), class 7 (machines and motors) and class 36 (finance, insurance and real estate), 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 3 (cosmetics and cleaning), class 10 (medical devices), class 30 (staples, spices and confectionery) and class 44 (medical, beauty and agricultural services), 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. "DIADEM" 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 3 similar names in the same classes (below).

Questions about DIADEM
Is DIADEM a registered trademark?
DIADEM has been applied for and advertised in the Trade Marks Journal (3 applications, latest on 20 October 2025). Advertisement means the Registry accepted the application; it is registered only if no opposition succeeds within four months of the journal date. The journal does not record the later outcome, so check the live register before relying on it.
Who applied for the DIADEM trademark?
As advertised: Dhanesha Crop Science PVT LTD; Armstrong Machine Builders Private Limited; plus 1 individual applicant.
Can I register a trademark similar to DIADEM?
Not for the same or related goods in class 5, class 7, class 36: a confusingly similar name is likely to be refused or opposed. For unrelated goods it may be possible after a search. Ask for a free availability report before you file.
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.
