The 90-Day Opposition Window: Tracking Nepal's Industrial Property Bulletin
How Nepal's 90-day opposition window works, when it starts, what the Industrial Property Bulletin actually contains, and the monitoring discipline that keeps the window usable.
Every trademark accepted in Nepal gets one public moment before it registers: publication in the Industrial Property Bulletin. From that publication, anyone with grounds has roughly 90 days to oppose.
The window is the only organised chance to stop a conflicting mark before it hardens into a registration. The hard part is not the opposition — it is knowing the application published at all.
In short
Accepted trademark applications in Nepal are published in the Industrial Property Bulletin, opening a roughly 90-day opposition window counted from the date of publication. Watches must review each issue promptly because late discovery compresses preparation into days. The window is the primary defence: an opposed application must answer, an unopposed one proceeds to registration and can only be attacked later by costlier routes such as non-use cancellation. Monitoring the Bulletin — searching by mark, applicant and class, across English and Nepali — is therefore the core defensive practice in Nepal's first-to-file system.
What the Bulletin is — and why it matters so much
The Industrial Property Bulletin is the Department of Industry's official publication of IP events — trademark applications accepted for publication, registrations, renewals and other register events, published periodically in Nepali and English. For a practitioner it is the dataset from which the entire defensive practice is built.
It matters because of the system's structure: Nepal is first-to-file, and publication is the moment an application becomes publicly attackable. Miss the Bulletin and the first you hear of the conflict may be the other side's certificate.

Counting the 90 days — carefully
The window runs from the date of publication. Counting is less trivial than it sounds: Bulletin dates are expressed in Bikram Sambat, Nepal's official calendar, so the deadline must be converted to AD before it enters a commercial calendar — a BS/AD slip of a day or two at a month boundary is a classic and unrecoverable error.
Treat the 90 days as a working countdown, not a buffer: the last two weeks should be for drafting, not for first review. A watch that reaches you on day 60 gives you a case assessment; a watch that reaches you on day 85 gives you a dilemma.
| Day | Checkpoint |
|---|---|
| 0 | Bulletin publishes — mark surfaces in the watch |
| 1–14 | First screen: same/similar mark, owner, class |
| 15–45 | Full conflict assessment; gather evidence of earlier rights |
| 46–75 | Decision: oppose, negotiate (coexistence/letter), or monitor |
| 76–85 | Draft and file opposition — with margin, not at the wire |
Reading a Bulletin issue like a practitioner
A watch is a review, not a glance. Each issue is scanned for marks that intersect yours on four axes: the word (across English, Nepali and transliterations — एभरेष्ट is Everest), the device/label where visual identity matters, the class and goods, and the applicant — repeat filers near your territory deserve attention even when the current mark is arguable.
The scan is tuned to produce candidates, not verdicts. A candidate list from each issue goes through human review — class, goods, script and context decide whether a lookalike is a threat or a neighbour.
- Search by mark (all scripts), applicant, and class — three passes per issue
- Transliteration is where naive searches fail in Nepal
- Track repeat applicants, not just individual marks
Who can oppose — and on what
Nepal's standing is practically generous: anyone may oppose an accepted application, and grounds track the registrability rules — Section 18(1) (similarity causing confusion, including across scripts, and prior rights), non-distinctiveness, descriptiveness, bad faith, and the use-related rules.
That breadth is a defensive gift: you do not need to be the prior registrant to protect your patch, only a party with real grounds. The flip side is that the examiner's acceptance is not a clearance — acceptance means no examiner objection, not no conflict.

The monitoring discipline
The window is only as good as the watch behind it. The workable cadence: review every Bulletin issue on publication (not in batches), keep a decisions log for every candidate mark (opposed / monitored / cleared — and why), and diarise each live window in BS and AD with the drafting deadline set a week before expiry.
Done that way, the 90 days become an orderly procedure instead of an emergency. Done any other way, they become the reason a competitor's registration now sits comfortably on the register.
