The patent application process in Nepal runs through the Department of Industry (DoI) under the Patent, Design and Trademark Act 1965. You lodge a written application with a specification and claims, the DoI examines the invention for novelty, inventive step and industrial applicability, you answer any objections, and — if it qualifies — the patent is granted for a renewable 7-year term. Because Nepal is not in the Patent Cooperation Treaty, you file directly. This guide focuses on the mechanics of that filing.
Key Takeaways
- Lodge the application with the Department of Industry under the Patent, Design and Trademark Act 1965.
- Include the specification, claims, abstract, drawings and applicant details in every patent filing.
- Draft layered claims — a broad independent claim plus narrower dependent fall-backs that survive examination.
- File promptly, because Nepal is first-to-file and priority runs from the date the DoI receives your application.
- Answer examiner objections in writing and amend claims, since prosecution decides most applications.
- Appoint a local agent by Power of Attorney if you file as a foreign applicant.
How does the patent application process work in Nepal?
You submit a written application to the Department of Industry with the invention's specification, claims, any drawings, an abstract and the applicant's details. The DoI checks the paperwork is in order, then examines the invention against the three patentability tests. You respond to any objections, and once the invention clears examination the patent is entered on the register and granted for a renewable term.
Think of the process as two phases. The first is entirely in your control: assembling a filing that is complete and technically sound. The second is in the DoI's hands: examination, objections and grant. Most applicants who run into trouble do so because the first phase was rushed — a thin specification or vague claims that cannot survive the second. Our end-to-end patent registration guide covers the strategy; this article stays on the filing mechanics.
What documents do you file with a patent application?
You file a written application form, the patent specification (a full technical description), the claims defining the scope of protection, an abstract, any drawings, and the applicant and inventor details. Where the applicant is not the inventor, you also file proof of the right to apply — an assignment or employment record — plus the government filing fee.
Two extra items apply to particular applicants. A foreign applicant must file a Power of Attorney appointing a local agent, because non-residents cannot prosecute a Nepali application on their own. And if you are claiming an earlier filing date from another country, you provide the priority details at filing. Getting names, entitlement and dates right on day one avoids objections that are tedious to fix later.
What goes into a patent specification?
A patent specification is built from standard parts: a title, a background explaining the problem the invention solves, a full description detailed enough for a skilled person to reproduce the invention, one or more claims that define the legal scope of protection, an abstract summarising it, and drawings where they help. The claims are the part that matters most.
The description and the claims do different jobs, and confusing them is a common drafting error. The description teaches: it must disclose the invention fully, because a patent is a bargain in which you disclose in exchange for a monopoly. The claims fence: each claim is a precise statement of what you are protecting. A description can be generous, but a claim must be exact — every word narrows or widens the monopoly.
Claims are usually layered. A broad independent claim states the invention in its widest defensible form, and narrower dependent claims add features as fall-back positions. If examination knocks out the broad claim over prior art, a dependent claim may still stand. This is why specification drafting is specialist work — the wording decides how much the patent is actually worth. See what can be patented in Nepal for the tests the claims must satisfy.
How do you file the application with the Department of Industry?
You lodge the complete application with the Department of Industry, which records the filing date — the single most important date in the whole process. Nepal is first-to-file, so priority runs from the moment your application reaches the DoI, not from when you invented. Two inventors with the same idea are separated by who filed first, which is why speed matters once the specification is ready.
At filing, the DoI issues an acknowledgement with an application number you use to track the matter. Make sure the applicant name exactly matches the entity that will own the patent — a company, not an individual founder, if the company is the intended owner — because correcting ownership afterwards is far harder than getting it right at filing. Foreign applicants file through their appointed local agent.
What happens during examination?
After the formalities are checked, the Department of Industry examines the invention: it verifies the application is complete and assesses whether the invention is new, involves an inventive step, is industrially applicable, and is not excluded from patenting. If the examiner finds a problem, the DoI issues objections, and you get an opportunity to respond in writing and, where needed, amend the claims.
This back-and-forth — often called prosecution — is where applications are won or lost. A good response does not just argue; it distinguishes your invention from the specific prior art the examiner cited, sometimes by narrowing a claim so it clearly sits beyond what already existed. Because examining an invention is detailed technical work and objections must be resolved before grant, this stage takes the bulk of the processing time.
What happens when the patent is granted?
If the invention clears examination, the Department of Industry grants the patent and records it in the patent register, giving you the exclusive right to make, use and sell the invention in Nepal. A patent runs for a term of 7 years and is renewable, so with timely renewals the protection continues. Once granted, the invention's disclosure becomes part of the public record.
Grant is not the end of your obligations. You must diarise the renewal dates, because a missed renewal can cause the patent to lapse and hand the invention to the public. You should also watch the market for infringement — a patent is only as strong as your willingness to enforce it — and keep your ownership records current if the business is restructured or the patent is assigned. If you licence the patent to a manufacturer or investor, record the arrangement properly so your rights and their permissions are clear, and make sure whoever manages the portfolio knows exactly when each renewal falls due.
What should you have ready before you file?
Before filing, have four things settled: a completed prior-art position so you know the invention is new, a drafted specification with claims, the correct applicant and inventor details with proof of entitlement, and — for foreign applicants — a signed Power of Attorney. Assembling these before you approach the DoI prevents the false starts that delay a filing date you cannot afford to lose.
The reason this preparation pays off is the first-to-file rule. Every week you spend fixing an incomplete filing is a week a competitor could file the same idea. A tidy application also draws fewer formal objections, which shortens the examination phase. If you are unsure whether your invention even qualifies before you invest in drafting, run it past the three tests in our what can be patented guide first.
How is the patent process different from a trademark?
A patent application is heavier than a trademark application in almost every respect. A trademark filing centres on a single mark and a class of goods, and it passes through a published 90-day opposition window. A patent filing centres on a technical specification with claims, and it is decided by substantive examination of the invention rather than by opposition. The skill sits in the drafting, not the search alone.
The practical consequence is timing and cost structure. A trademark can often be handled with a straightforward filing; a patent involves searching, specialist drafting and a prosecution exchange with the examiner that can run for a long time. If you are protecting both an invention and the brand it sells under, you file them separately — see our broader guide to intellectual property law in Nepal.

How do you start a patent application in Nepal?
Start by locking down the invention's novelty and getting the specification drafted, because those two decide the outcome long before the DoI sees the file. When you are ready, use our patent registration service or talk to an IP expert — we run the prior-art search, draft the specification and claims, file with the Department of Industry, and carry the application through examination to grant.
