How to File a Trademark Opposition in Nepal: Grounds and Evidence
Filing a trademark opposition in Nepal: the grounds under the PDTA, the evidence that carries each ground, procedure at the Department of Industry, and drafting that wins.
You have a published application in your sights and a window that is running. An opposition is now a writing exercise with a deadline: the right grounds, honestly evidenced, filed in time.
This guide sets out how an opposition is actually put together in Nepal — the legal grounds, the evidence that carries them, the procedure, and the drafting choices that separate winners from scattershots.
In short
A Nepalese trademark opposition is filed at the Department of Industry within ~90 days of the application's Bulletin publication, on written grounds under the PDTA — principally Section 18(1) similarity (including across English/Devanagari scripts) and prior rights, plus non-distinctiveness, descriptiveness and bad faith. The opposition states grounds with supporting evidence: prior registrations and use records, comparison exhibits and, where relied on, evidence of reputation. The applicant answers; the Department decides on the papers and submissions. Precision beats volume: fewer, better-evidenced grounds.
First, a candid merits assessment
Oppositions cost money and time; they are worth filing when the grounds are real. Before anything is drafted, answer the boring questions: Is the marks' similarity genuine — visually, phonetically, conceptually — including in translation? Are the goods actually close, or merely in the same class number? Is your prior right documented (registration, use, reputation), or an anecdote? Would a consumer briefly hearing both names in a Kathmandu shop plausibly mix them up?
If the honest answers cluster around 'arguable', a negotiated route — a coexistence proposal or a letter to the applicant — may achieve more than a proceeding. If they cluster around 'yes', the opposition is simply the correct next step.
The grounds, and the evidence each one needs
Grounds under the PDTA are the classic set, and each is only as strong as the exhibit behind it.
The strongest Nepalese oppositions usually rest on similarity + prior right. Section 18(1) in Nepalese practice is script-aware: a Devanagari application can conflict with your Latin mark when the sounds match — which is why the comparison exhibit should always include the transliterated forms.
| Ground | Core authority | Evidence that carries it |
|---|---|---|
| Similarity / likelihood of confusion | Section 18(1) | Side-by-side comparison exhibit; phonetic analysis incl. Devanagari forms; your registrations |
| Earlier rights / prior use | Section 18(1); first-to-file practice | Your earlier registration certificate; dated use records in Nepal; priority documents |
| Lack of distinctiveness | Section 18(1) | Category survey of the trade; evidence the sign is the common name/shape for the goods |
| Descriptiveness / deception | Section 18(1) | Dictionary and trade usage; evidence consumers would be misled about origin/quality |
| Bad faith | General principles | Pattern of filings by the applicant; correspondence; timeline showing they moved on your launch |

Procedure at the Department
The mechanics are parliamentary, not theatrical. The opposition is filed in writing at the Department of Industry within the window, stating grounds and attaching evidence, with the fee. The applicant is put to answer; the exchange proceeds on submissions, with the Department able to request further material or a hearing. The decision issues in writing, with appeal rights to the Revenue Tribunal / relevant court thereafter.
What this means tactically: the papers are the case. The examiner decides from what is filed — so exhibits must be self-explanatory, translations of Nepali documents supplied where the officer needs them, and every factual claim pinned to an exhibit.
- File within the window at the DOI — grounds + evidence + fee
- Applicant answers; decision on the papers (hearings where required)
- The written record is the whole case — exhibits must speak for themselves

Drafting that wins
Experienced opposers file fewer grounds, better evidenced. The discipline: lead with the strongest similarity case and the best prior right; make the comparison exhibit do the arguing (mark vs. mark, goods vs. goods, scripts aligned); quantify your use and reputation with dates, not adjectives; and pre-empt the obvious defences (different classes? different trade channels? regional coexistence?) rather than hoping the officer misses them.
Keep the tone factual. Oppositions are read by examiners, not juries — the persuasive register in Kathmandu is calm, precise, and documented.
- Two strong grounds beat five thin ones
- The comparison exhibit argues so you don't have to
- Dates and documents over adjectives
After filing: the clock you still own
An opposition freezes the application but not your calendar: track the applicant's answer deadline, respond to requests for evidence promptly, and keep the underlying prior registrations renewed — an opposition grounded on a mark that lapses mid-proceeding is a self-inflicted defeat. And if the opposition fails, know your appeal route and the monitoring plan for the mark that prompted it.
