PCT National Phase Entry for Nepal: Deadlines, Documents and the DOI Process
PCT national phase entry for Nepal: what international applicants must file at the DOI, the documents and translations needed, and how to plan the deadlines.
Your international patent application has been published, the search report is in, and the markets map now includes Nepal — a PCT member where the invention can be protected by entering the national phase at the Department of Industry.
National phase entry is where the international convenience ends and local procedure begins: the forms, the translations and the deadline discipline are Nepal's own.
In short
PCT national phase entry for Nepal converts an international application into a Nepalese patent filing at the Department of Industry: the application proceeds on Nepal's forms with the specification translated into Nepali, inventor and applicant particulars, and a local agent's mandate for foreign applicants. Plan the entry against the Treaty's time limits — international practice centres on the 30-month mark from the priority date for Chapter I routes, but confirm the current Nepalese time limit with the DOI or your agent before relying on the outer boundary — and remember that a direct Paris Convention route (12 months from priority) remains the alternative for applicants who missed the PCT train.
Nepal's place in the PCT system
Nepal is a member of the Patent Cooperation Treaty, which means an international application can designate Nepal and be brought into the national phase here — the route that lets a single international filing mature into national patents across PCT members, country by country. It is a meaningful change from the era when every Nepalese patent required a standalone filing from day one.
What the PCT does not do is grant the patent. The international phase delivers filing, search and — optionally — preliminary examination; the grant comes from the national office. For Nepal, that is the Department of Industry, working under the Patent, Design and Trade Mark Act, 2022 BS (1965), whose examination runs through a technical committee convened for each application.
The deadline planning
National phase deadlines are the PCT's arithmetic applied locally. In international practice, Chapter I national phase entry commonly falls at 30 months from the priority date (Chapter II, with preliminary examination, can extend the practical runway in many offices). For Nepal specifically, confirm the current time limit and its computation — priority date versus international filing date — with the DOI or the local agent before building the docket: the planning rule is to treat the outer limit as a ceiling for filing, not a target for starting translation.
Two parallel clocks matter alongside it. The Paris Convention's 12-month priority window still governs direct national filings, which is the fallback route for inventions whose PCT strategy changed. And the DOI's own response clocks — examination queries answered within the stated period — run on the Department's calendar once the application is in.
What the national phase filing contains
| Item | Detail |
|---|---|
| Application documents | Nepal's prescribed forms, carrying the international application's particulars |
| Specification | Translated into Nepali — the description, claims and drawings the technical committee will read |
| Inventor details | Name, address and occupation, as the Act requires |
| Basis of applicant's right | Assignment or employment basis where the applicant is not the inventor |
| Agent mandate | Notarised Power of Attorney for foreign applicants; legalised through the consular chain |
| Fees | NPR 1,000 application and NPR 7,000 registration in current practice; annual maintenance follows |
The entry workflow
Decide Nepal's place in the family early
The decision shapes everything downstream: which claims enter, whether the Nepalese market justifies the full specification or a narrowed one, and how the translation budget is set. Markets decide filings; filings should not decide markets by accident.
Commission the Nepali translation early
The translation is the disclosure the technical committee examines — terminology consistency, process steps and claim structure all matter. Start it months before the deadline, not weeks; translation is the longest lead item in the entry package.
Assemble the agent mandate and corporate papers
The notarised POA for the local agent follows Nepal's legalisation chain — 2–6 weeks from notarisation to Nepalese mission legalisation. Build that lead time into the entry calendar.
File and run the national examination
After entry, the application is examined like any Nepalese filing — formality checks, then the technical committee, whose findings loop back for amendment. Respond within the stated periods; accepted patents publish in the Nepal Gazette, with objections lying within 35 days of publication, and the term runs 7 years from registration, renewable twice.
What national phase entry costs over the patent's life
The entry fees are the beginning of the arithmetic: NPR 1,000 at application and NPR 7,000 at registration in current practice, then annual maintenance — NPR 5,000 per year across years 7–14 and NPR 7,500 across years 14–21, with a NPR 1,000 fine inside each 6-month grace window. Add translation, agent fees and the docketing overhead of a deadline that lives outside the PCT's international cycle.
The planning habit that works: enter Nepal deliberately, with a market rationale and a maintenance budget — not by default, because the designation box was available.
