What Can Be Patented in Nepal? Novelty, Step & Utility (2026)

What can be patented in Nepal depends on three tests applied by the Department of Industry (DoI) under the Patent, Design and Trademark Act 1965: novelty, inventive step and industrial application. A patent usually protects a workable product or process, not an abstract idea, discovery or purely visual creation.

Key Takeaways

Patentability in Nepal requires a technical invention that is new, non-obvious and usable in industry. The DoI examines the application, publishes it, allows opposition, and then issues a certificate if the legal requirements are met.

• Nepal applies a first-to-file approach, so filing early matters more than proving who first thought of an invention.
• Novelty can be lost through your own publication, sale, demonstration or public explanation before filing.
• Inventive step means the solution must not be an obvious change for a skilled person in that technical field.
• Industrial application means the invention can be made or used in some form of industry.
• Patents protect function; industrial designs protect appearance; trademarks protect names, logos and other brand signs.
• NICE classes apply to trademarks, not patents. A patent application describes the invention through a specification and claims.
• A prior-art search and careful claim drafting can expose problems before you commit to a full filing.

What can be patented in Nepal?

Nepal can patent a new and useful product or process that provides a technical solution. The DoI assesses whether the invention is novel, involves an inventive step and can be applied industrially under the Patent, Design and Trademark Act 1965.

A patentable product may be a device, machine, component, material, composition or technical system. A patentable process may explain how to manufacture something, treat a material, operate equipment or achieve a practical technical result. The key question is not whether the idea sounds clever. It is whether the claimed subject matter works as a technical solution.

For example, imagine a Nepali engineering team develops a low-power irrigation controller that uses soil conditions to reduce water waste. The controller, its technical arrangement and a defined operating process may be patent candidates. The business plan, market strategy or general goal of “saving water” is not the invention by itself.

What does novelty mean for a Nepal patent?

Novelty means the invention was not publicly disclosed before the relevant filing date. Earlier patents, journal articles, manuals, websites, products, sales, demonstrations and public use can form prior art and may prevent the same invention from being patented.

“Prior art” means information or technology already available to the public. It does not matter whether the earlier disclosure came from Nepal or another country. It also does not usually matter that you created the invention independently. If the same technical teaching was already public, your application may fail the novelty test.

Your own disclosure can create the same problem. A product launch, trade fair demonstration, crowdfunding page, university presentation or public social-media post may reveal the invention too early. Keep records confidential and use a suitable non-disclosure agreement with investors, manufacturers and consultants.

Nepal is first-to-file. That means the earliest valid application generally has the stronger priority position, rather than the person who can simply say they invented it first. File before public disclosure whenever possible.

What is an inventive step or non-obviousness?

Inventive step asks whether a skilled person in the relevant field would regard the claimed solution as an obvious development of what was already known. A new invention still needs a real technical advance, not just a routine substitution or predictable adjustment.

Suppose an existing water filter uses one known material and your proposal replaces it with another material that performs exactly as expected. That change may be new in wording but obvious in substance. By contrast, a particular arrangement that solves a difficult clogging problem and produces an unexpected improvement may support an inventive-step argument.

The DoI will look at the invention as claimed and at the technical information supporting it. Claims are the legal boundaries of the patent. Overly broad claims may collide with prior art; claims that are too narrow may leave competitors room to design around them.

Inventive step is often the hardest patentability criterion to assess from a short description. A prior-art search should identify the closest technology, the difference between it and your invention, and the technical result produced by that difference.

What does industrial application or utility require?

Industrial application means the invention can be made or used in some kind of industry. In practical terms, it must work as described and provide a repeatable, useful result, rather than remain an unsupported theory or impossible concept.

“Industry” has a broad practical meaning. It can include manufacturing, agriculture, energy, food processing, medical equipment, software-linked machinery and other productive activity. The invention does not need to be a large factory product. A small component or process may qualify if it has a real technical use.

Describe how the invention operates, what materials or inputs it needs, and how someone can make or use it. Drawings, test results, prototypes and examples can help explain the technical effect, although the exact evidence needed depends on the invention.

Which NICE classes apply to a patentable invention?

NICE classes do not classify patents in Nepal. The 45-class Nice Classification applies to trademarks: Classes 1–34 cover goods and Classes 35–45 cover services, with one trademark application required per class.

This distinction prevents a common filing error. If you are registering the name of your invention, you may need a trademark and therefore a NICE class. If you are protecting how the invention works, you need a patent application with a specification and claims.

A product can need several rights. A new kitchen appliance might have a patent for its mechanism, an industrial design for its casing and a trademark for its brand name. The rights can work together, but one registration does not replace the others. The NICE Classification guide is useful only for the trademark part.

What generally cannot be patented in Nepal?

Nepal generally does not patent a mere discovery, abstract idea, scientific theory, mathematical principle, business concept or purely aesthetic creation as an invention. A routine modification that lacks an inventive step can also fail, even if it has not appeared in exactly the same form.

Finding a plant property in nature is a discovery. A technical process that extracts, converts or uses that property may be a different question. Likewise, a scientific principle is not the same as a machine that applies the principle. The technical implementation must be described clearly and assessed on its own facts.

A product’s visual appearance belongs in industrial design protection, while its name or logo belongs in trademark protection. A broad app concept or business model is not enough by itself. A technical computer-linked invention may need careful analysis of the actual technical contribution rather than a claim to software in the abstract.

These are practical categories, not a substitute for reviewing the current Act and DoI practice. The official Nepal Law Commission legal materials and the Department of Industry are appropriate starting points for the governing framework.

How can you check whether an invention is patentable?

Check patentability by preserving confidentiality, searching prior art, identifying the technical difference, testing practical use and then preparing claims. This review should happen before filing because a weak first application can limit the protection you later obtain.

1. Write the invention down. Record the problem, technical solution, drawings, versions, testing and dates. Identify every contributor and the likely applicant.
2. List all disclosures. Include demonstrations, sales, publications, online posts, investor decks and discussions with suppliers. Mark what was confidential and when.
3. Search prior art. Search patent documents, technical publications, product information and related technologies. Use different terms for the same component or process.
4. Compare the closest results. Explain what your invention adds and why that difference produces a useful technical result. This is more valuable than merely finding no identical title.
5. Plan the claims. Define the essential technical features and prepare a specification that teaches a skilled person how to perform the invention.
6. File before disclosure. The DoI filing fixes the important priority point in Nepal’s first-to-file system. Foreign priority documents may be relevant in an eligible case.

What documents are needed for patent registration?

A Nepal patent filing normally needs the prescribed application, a notarised Power of Attorney, and a clear specification and claims. If you claim foreign priority or have a foreign patent, certified or notarised supporting documents may also be required.

The specification should explain the invention in enough detail for a skilled person to understand and carry it out. Claims define the protection requested. Drawings, diagrams, examples and technical data should match the claims and use consistent terms.

Prepare applicant details, inventor information, ownership documents and any assignment evidence early. A company may need internal authority showing that the filing is properly approved. Foreign applicants generally need a Nepal-based agent or representative because Nepal is not part of the PCT system.

Do not publish the full invention while documents are being prepared. A patent attorney or technical adviser can also check whether the proposed claims describe one invention or improperly combine separate concepts.

What is the Nepal patent registration process?

The Department of Industry follows a sequence of application, examination, publication, opposition and registration. For patents, interested persons may object within 35 days of publication, and the certificate follows if the application survives examination and any valid opposition.

1. File the application: submit the form, specification, claims, Power of Attorney and priority documents where relevant.
2. DoI examination: the Department examines whether the invention is new and useful and may raise questions or objections.
3. Respond to examination: provide explanations or permitted amendments that address the examiner’s concerns without changing the invention improperly.
4. Publication: an accepted application is published for public information in the Industrial Property Bulletin.
5. Opposition period: an interested person may file an objection within the patent opposition period of 35 days.
6. Registration and certificate: if there is no valid objection, the patent is registered and the certificate is issued after the required registration step.

An opposition is a formal challenge by another interested person. It can delay registration and require evidence or legal submissions. Patent and trademark opposition periods are not the same: the patent period is 35 days, while the commonly used trademark period is 90 days.

How long does a patent take in Nepal?

A Nepal patent application typically takes about 12–14 months from filing to certificate when it is unopposed. A straightforward case may finish in about 6–8 months, but that is the favourable fast end, not the normal planning assumption.

Timing depends on the quality of the specification, examination questions, amendments, publication schedules and opposition. Missing a response deadline or submitting unclear drawings can add delay. A technical invention with several claim issues may take longer than a simple, well-supported application.

How long does a Nepal patent last?

A Nepal patent is valid for 7 years and may be renewed twice for additional 7-year terms, subject to the required renewal steps. The maximum term is therefore 21 years, provided the owner maintains the right correctly.

Renewal is not an administrative detail to leave until the last moment. Record the registration date, ownership changes and renewal deadlines. If the patent is assigned, the ownership record should also be kept consistent with the DoI register.

What does patent registration cost in Nepal?

Patent cost depends on government filing and registration charges, professional drafting, technical drawings, prior-art searching, translation, notarisation, agent work and responses to examination. The total also changes if priority documents, ownership changes or opposition work are involved.

Patent drafting usually drives the professional cost because claims must be technically accurate and legally useful. A low-effort filing can create a cheap document that does not protect the commercial product. Ask for a current estimate based on the invention, documents and expected work through IP Sewa’s contact team, rather than relying on an old online figure.

What are the most common patent mistakes in Nepal?

Common mistakes include public disclosure before filing, treating a business idea as an invention, skipping prior-art research, using vague claims, confusing a design with a patent, and assuming a foreign filing automatically protects Nepal.

• Disclosing too soon: file before a public launch, demonstration or sale.
• Describing the goal instead of the solution: explain the technical structure or steps that achieve the result.
• Copying a foreign patent: foreign registration does not automatically create Nepalese protection.
• Ignoring inventorship and ownership: identify contributors and document transfers before filing.
• Using the wrong right: file an industrial design for appearance and a trademark for brand identity.
• Underestimating opposition: publication is not the certificate; an interested person can object within the applicable period.

Can a foreign applicant patent an invention in Nepal?

A foreign applicant must generally file directly in Nepal through a Nepal-based agent or representative because Nepal is not a member of the PCT. A Paris Convention priority claim may be available, but it does not remove the need for a Nepal filing.

Nepal also is not in the Madrid System for trademarks or the Hague System for designs. An international filing elsewhere does not automatically cover the Nepalese market. Gather certified or notarised foreign filing, priority or registration records in the form the DoI requires.

For a foreign-owned invention, confirm the applicant, inventor, assignment chain and Power of Attorney before filing. Local representation helps with notices, examination responses and formal communication with the Department.

What is the best patentability example for a Nepal business?

Imagine “Himalayan Harvest Foods,” a fictional Nepali startup, develops a machine that dries ginger at a controlled temperature while cutting energy use. The machine may be patentable if it is new, non-obvious and workable, while its name and casing may need separate rights.

The company should keep test results and drawings confidential, search existing drying machines, identify the technical feature that creates the energy saving, and draft claims around that feature. A claim to “selling better dried ginger” would not protect the technical invention.

The example also shows why commercial planning should follow legal classification. The food brand may need trademark protection. The machine’s appearance may qualify for industrial design protection. The drying mechanism is the possible patent subject.

What should you do before filing a Nepal patent?

Before filing, preserve confidentiality, document the invention, search prior art, identify the right applicant and prepare a technically complete specification. Treat the first filing as a strategic document because it sets the foundation for examination, ownership and later enforcement.

Patentability is never guaranteed by a search result. The DoI makes the formal decision after examination. Still, a careful review can reveal whether you should refine the invention, file a design, register a brand, or proceed with patent drafting.

In short: what can be patented in Nepal is a new, non-obvious and industrially useful technical product or process. File early at the DoI, protect confidentiality, prepare strong claims, expect about 12–14 months when unopposed, and maintain the patent through its renewable terms.
