What Is a Patent in Nepal? Patent Protection Under the PDTA, Explained

What counts as an invention in Nepal

Section 2(a) of the PDTA defines patentable subject matter functionally: an invention is new if it involves a method or process, a method of operation or transmission of a material, or an invention based on a new theory or formula. The definition is weighted toward process and utility inventions — how something is made or works, not merely how it looks.

Two consequences follow. First, a disclosure must describe how the invention works in enough detail that a person in the field could understand and reproduce it. Second, the fields where Nepalese inventive activity actually concentrates — food processing, herbal formulations, mechanical adaptations, agri-equipment — sit squarely within the framework.

What patent protection in Nepal gives you — and what it does not

A granted patent gives the proprietor exclusive rights in the invention for the term: the standing to stop others working the invention commercially, to license it, to record its assignment, and to enforce against infringers. The registration certificate, published in the Nepal Gazette under Section 7A, is the public proof of the right.

It does not give automatic enforcement, protection outside Nepal, or cover for subject matter that belongs to other rights — the look of a product files as an industrial design, the brand on it files as a trademark, and software's code is protected by copyright. And it demands use: maintenance fees keep it alive year by year, and a lapsed patent cannot simply be refiled, because the published specification is prior art against its own refiling.

How you get one: the DOI process

The application is filed on Schedule 1(a) at the Department of Industry with the full description, drawings where needed, and inventor details. After formality checks, the DOI constitutes a technical committee — experts from government technical bodies and institutions such as NAST and RECAST — to examine the disclosure; the applicant may amend in response, and the committee can re-examine before a final decision.

Accepted patents publish in the Nepal Gazette, with objections lying within 35 days of publication. On a favourable outcome the registration fee is paid and the patent registers. Total elapsed time typically runs a year or more.

Term, fees and the 21-year ceiling

The annual structure turns holding a patent into a yearly maintain-or-lapse decision: keep it while the invention is worked — made, sold, licensed or held defensively — and lapse it deliberately when it is not.

The international picture

Nepal is a member of the Paris Convention and the PCT. The Paris route gives a 12-month priority window: a Nepalese application filed within a year of a first filing abroad can claim the earlier date — decisive in a system where published prior art anywhere can defeat novelty. PCT international filings can reach Nepal through the national phase, where the DOI examination applies as for any national application.

Foreign applicants file through a local agent under a notarised Power of Attorney, with the specification in Nepali translation. And the draft Industrial Property Bill 2082 — still proposed — would align patentability standards and terms with TRIPS; until it is enacted, the structure above is the law.

Is a Nepalese patent the right tool for your invention?

The honest test is commercial: does the invention earn enough, or block competitors seriously enough, to justify annual fees for up to 21 years? For a process that underpins a product line, usually yes. For an invention you would abandon in five years, a documented trade secret or a design filing on the product's look may be the better buy.

Whatever the answer, decide before disclosing: publication, trade fairs and sales pitches consume novelty, and Nepal's system offers no grace for an invention that went public before it was filed.
