Claiming Paris Convention Priority in Nepal
How Paris Convention priority works in Nepalese filings — the 6/12-month windows, the documents and wording an application needs, and the mistakes that forfeit the earlier date.
Paris Convention priority is the quiet workhorse of foreign IP filings in Nepal: the rule that lets a Nepalese application carry the filing date of your first application anywhere in the Paris Union — 6 months for trademarks and designs, 12 for patents.
It is claimed in the application itself, and it is forfeited by details as small as a misnamed prior application. This guide covers the mechanism as Nepal practices it.
In short
Nepal, a Paris Convention member, applies Convention priority to national filings: a trademark or design application filed within 6 months of the first filing in any Paris/WTO country (12 months for patents) can claim the first filing date as its priority date. The claim is made in the Nepalese application — identifying the prior application, country and date — and supported by a priority certificate from the first office where required. The earlier date matters in Nepal's first-to-file system: it out-ranks intervening local applications and squatter filings. Common forfeits: late filing beyond the window, mismatched applicant names, and specifications broader than the prior application's disclosure.
The mechanism and the windows
Paris Convention Article 4 gives any applicant who has duly filed in one member country a right of priority for filings in other member countries: 6 months for trademarks and industrial designs, 12 months for patents. Nepal, a Paris Union member since 2001 and a WTO/TRIPS member, applies the rule to its national filings — a Nepalese application filed inside the window can claim the first filing's date as its priority date.
Why the date matters so much here: Nepal is first-to-file, and the register records actual filing dates. A priority claim back-dates your position — an application filed in Nepal in December, claiming a June priority date, defeats a local squatter's October filing. Priority is the one doctrine that outranks the local filing race.
- 6 months: trademarks and designs; 12 months: patents
- Claimed inside the Nepalese application itself
- The claimed date out-ranks intervening local filings

Making the claim properly
The claim lives in the details, and the details are checkable. The Nepalese application should identify the priority claim — the country, office, application number and date of the first filing — and the applicant should be able to produce a priority certificate (or certified copy) from the first office where the Department requires it. Multiple priorities can be claimed within the windows, each attaching to the parts of the specification it supports.
Three precision points decide most disputes. Same invention/mark: the priority claim reaches only what the first application actually disclosed — new matter added in Nepal gets the Nepalese date, not the priority date. Same applicant or successor: the claimant must be the first applicant or their assignee — name changes mid-window need the assignment papers. Inside the window, in calendar terms: the 6/12 months run from the first filing date, and a deadline that lands on a Nepalese holiday extends to the next working day — but a deadline missed is a claim lost.
- State the priority claim in the application: country, number, date
- Priority reaches only what the first filing disclosed — no new matter
- Applicant continuity matters: successors need the assignment chain

What priority does — and does not — buy
Priority buys a date. In a first-to-file system the date is leverage: it out-ranks later local applications, it anchors opposition and conflict analysis, and for patents it defines the prior-art cutoff. What it does not do: substitute for the filing's own formalities (POA, fees, translations), exempt the application from examination, or protect acts of use between the priority date and the Nepalese filing date — brand-building during the priority window is still exposure until the Nepalese application is actually in.
For multi-country rollouts, the working pattern: file the home application first, file in Nepal early in the priority window, and let the claimed date do the racing. The window exists to be used, not to be discovered at month five.
- Priority = a better date, not fewer formalities
- File early in the window — use-based exposure runs until filing
- Sequence: home filing → Nepal filing → market entry
Priority vs. the documents trap
One caution connects priority to procedure: the documents that support a foreign filing (POA, corporate papers, priority certificates) take legalisation time — and Nepal's consular-legalisation regime is slower than apostille countries expect. Build the document lead time into the priority calendar: a claim forfeited to a missing legalised POA is the most avoidable defeat in foreign practice.
