Nepal has no utility model or petty patent system. Under the Patent, Design and Trademark Act 1965 (PDTA), the Department of Industry (DoI) offers one patent route for functional inventions, with examination, publication and a 35-day opposition period before registration.
Key Takeaways
Nepal recognises patents, industrial designs and trademarks under the PDTA, but no separate utility-model right. A patent lasts seven years and may be renewed twice, while an industrial design is the better route for a product’s new appearance rather than its technical function.
- Nepal does not issue utility models, petty patents or utility certificates.
- A functional improvement must use the standard patent process at the Department of Industry.
- A new product shape, pattern or ornament may qualify for industrial design registration instead.
- Patent applications face DoI examination, publication and a 35-day opposition window.
- A Nepali patent initially lasts seven years and can be renewed twice, up to 21 years in total.
- Nepal is first-to-file and outside the PCT, so an overseas filing does not automatically protect an invention here.
Does Nepal have a utility model or petty patent?
Nepal does not provide a utility model, petty patent or utility certificate under the PDTA. The DoI administers one patent regime for inventions that are new and useful, followed by publication and a 35-day opposition period before the registration certificate is issued.
A utility model is a separate right found in some jurisdictions. It commonly protects smaller technical advances under rules that may be faster or less demanding than ordinary patent rules. That foreign concept can cause confusion for founders entering Nepal, especially where an adviser uses the terms “minor invention” or “petty patent.”
In Nepal, the law does not create a second route for an incremental mechanical improvement. It makes no difference whether your innovation is a breakthrough machine or a useful change to a farm tool: if you are protecting how it works, the relevant route is a patent application at the DoI.
What does a utility model mean outside Nepal?
A utility model generally means a country-specific right for a practical, incremental invention, often with a shorter term than a standard patent. Nepal does not adopt that model, so the seven-year renewable patent term under its PDTA remains the local route for technical inventions.
In countries that use them, utility models may cover improvements to tools, devices, fittings or mechanical parts. They are sometimes called petty patents because they can be aimed at less complex innovations. The exact rules vary widely by country, including what can be protected, how much examination occurs, and how long protection lasts.
Do not assume that a foreign utility-model registration gives rights in Nepal. Intellectual property is territorial: a right exists only where the local law recognises it. Nepal is not part of the Patent Cooperation Treaty (PCT), so there is no PCT route that automatically turns an overseas application into a Nepali patent.
How is a Nepali patent different from a utility model?
A Nepali patent is the only statutory right for a new and useful technical invention, examined by the DoI before publication. Unlike a utility model elsewhere, it has a seven-year initial term and may be renewed twice, rather than offering a separate shorter protection tier.
| Feature | Utility model in countries that offer one | Patent in Nepal |
|---|---|---|
| Available in Nepal? | No | Yes, through the Department of Industry |
| Purpose | Often used for smaller technical improvements | Protects a new and useful invention |
| Legal basis | Depends on that country’s own law | Patent, Design and Trademark Act 1965 |
| Local examination | Varies by jurisdiction | DoI examines the application before publication |
| Opposition | Varies by jurisdiction | Interested persons may object within 35 days of publication |
| Term | Usually a separate, shorter term | Seven years, renewable twice up to 21 years |
The practical point is not that a minor invention has no protection in Nepal. It may still qualify for a patent if it is genuinely new and useful. The point is that you should not plan for an easier second-tier filing that the statute does not offer.
How do founders register a minor invention in Nepal?
Founders register a qualifying functional improvement by filing a patent application with the DoI, which examines whether it is new and useful. The process then moves through publication, a 35-day opposition period, registration and a certificate, with an initial seven-year patent term.
- Define the technical solution. Set out what the invention does, how it works, and what makes it different from known products or processes. A patent protects the technical idea expressed through its specification and claims, not a broad business ambition.
- Check existing knowledge. Review prior patents, published material and products already in the market. A prior-art review helps you judge whether the invention appears new before you disclose it publicly.
- Prepare the application papers. The specification explains the invention in enough detail for it to be understood. Claims define the legal boundary of the protection you seek.
- File at the DoI. The filing date matters because Nepal follows first-to-file principles. File before launching, pitching without confidentiality, posting drawings online, or showing the product at a trade event.
- Respond during examination. The DoI assesses whether the invention is new and useful. Clear technical drafting makes this stage far easier than trying to repair a vague filing later.
- Wait through publication and opposition. If accepted, the application is published. An interested person may object within 35 days, after which the DoI decides whether registration can proceed.
Which documents does a patent application need?
A patent application needs the prescribed form, a notarised Power of Attorney, and a specification with claims that define the invention. Where foreign rights or priority are relevant, certified filing or registration records may also be needed for the DoI’s patent process.
- Patent application form: the formal request for registration.
- Notarised Power of Attorney: authority for a representative to act for the applicant.
- Specification and claims: the technical description and the legal scope of the invention.
- Supporting drawings, where needed: clear illustrations can be essential for a mechanical device or product configuration.
- Foreign filing material, if applicable: certified or notarised copies of a foreign application, filing receipt or registration certificate may support a priority-based filing.
Claims deserve special care. They are not marketing language. A claim should identify the technical features that make the invention different. Our team can help founders prepare and file a properly scoped application through our patent registration service in Nepal.
Should you choose a patent, industrial design or trade secret?
You should choose a patent for a new technical function, an industrial design for a new visual appearance, and confidentiality for valuable know-how that is not publicly disclosed. Patents have a seven-year renewable term, while industrial designs begin with a five-year term and are renewable.
Imagine a Pokhara startup developing a spill-resistant momo steamer. Its new pressure-release mechanism may be a patent issue because it changes how the steamer works. Its distinctive leaf-shaped outer casing may be a design issue because it changes how the product looks. Its supplier list and production settings may be kept confidential through contracts.
One product can involve more than one right. The patent and design routes are separate applications, with separate requirements and certificates. For an appearance-led product improvement, our industrial design registration support can help you assess the drawings and filing approach.
Do NICE classes apply to patents in Nepal?
NICE Classification does not apply to patent applications in Nepal because it is a trademark classification system for goods and services. Patent protection instead depends on the invention’s technical description and claims, examined by the DoI under the PDTA before the 35-day opposition stage.
The NICE Classification has 45 classes and matters for trade mark, logo and business-name protection. It does not divide patent applications into classes or allow a founder to reserve a technical concept. If your product also has a name or logo, that brand may need separate trademark registration alongside the patent.
If you are unsure whether a feature is functional or merely visual, document the product before filing. Photographs can help explain the commercial product, but patent specifications and claims must explain the technical solution.

What are the timeline, term and cost factors for patents?
The patent process includes DoI examination, publication and a fixed 35-day opposition window, so completion depends on the application’s quality and any objection. A registered patent starts with a seven-year term and may be renewed twice, creating a maximum possible term of 21 years.
There is no reliable one-size-fits-all completion date for patent registration. Technical complexity, the clarity of the claims, supporting documents, examination questions and any opposition can all affect progress. A well-prepared filing reduces avoidable back-and-forth, but it cannot remove the statutory publication and opposition stages.
Total cost depends on government charges, professional work, technical drafting, drawings, translations, notarisation, priority material and later renewals. A mechanical invention with detailed claims often needs more preparation than a simple design filing. For a current estimate based on your invention and documents, please speak with our team.
What legal rules and foreign-filing issues should founders know?
The PDTA governs patent registration in Nepal, and the DoI is the authority that examines and registers applications. Nepal is first-to-file, so the earliest valid local filing is critical; its seven-year patent term can be renewed twice under the statutory renewal framework.
You can read the official Nepal Law Commission legal materials and check current administrative information through the Department of Industry. WIPO also explains international intellectual-property systems, but a foreign patent or utility model does not itself create protection in Nepal.
Foreign applicants should file directly in Nepal through a Nepal-based representative. A Paris Convention priority claim may be relevant where the facts support it, but it should be assessed before filing. This article is general information, not legal advice; the right filing strategy depends on the invention, disclosure history and foreign filings.
What mistakes do founders make with minor invention protection?
Founders often lose options by publicly disclosing an invention before filing, assuming a foreign petty patent covers Nepal, or confusing product appearance with technical function. Because Nepal uses first-to-file principles and a 35-day patent opposition stage, early preparation and accurate right selection matter greatly.
- Calling every improvement a utility model: Nepal has no such statutory category, so begin with patentability and design questions instead.
- Filing vague claims: a claim that does not identify the technical difference may fail to protect the feature that creates commercial value.
- Using a patent for decoration: a new casing shape or surface pattern is usually better assessed as an industrial design.
- Launching before filing: public demonstrations, sales material and online posts may complicate a novelty assessment.
- Ignoring renewals: a patent does not remain in force indefinitely without the required renewal action.
In short: “utility model Nepal” is a search for a right Nepal does not offer. If your improvement changes how a product works, assess a standard patent. If it changes how the product looks, assess industrial design registration. Protect confidential know-how through practical controls until you decide what to file.
