Patent Registration in Nepal: A Step-by-Step Guide (2026)

Patent registration Nepal means filing a technical invention with the Department of Industry (DoI) under the Patent, Design and Trademark Act 1965 (PDTA). A straightforward, unopposed application may take about 12–14 months, although the smoothest cases can finish sooner. Nepal requires a direct national patent filing because it is outside the PCT.

Key Takeaways

The Department of Industry registers patents under the PDTA, and a granted patent lasts seven years before renewal is due. You must file directly in Nepal, prepare a clear specification and claims, pass DoI examination, and address any opposition filed within 35 days of publication.

• A patent protects a technical invention or process, not a business name, logo, product appearance, or general idea.
• Nepal is first-to-file, so an early complete application is usually safer than relying on first use or informal records.
• Keep the invention confidential before filing because public disclosure can undermine whether it is new.
• The specification explains how the invention works; the claims define the legal boundary of protection.
• The DoI publishes an accepted patent application, and interested persons have 35 days to object.
• A Nepal patent has a seven-year term and may be renewed twice for further seven-year periods.
• Foreign applicants need a Nepal-based agent or representative for their direct national filing.

What does a patent protect in Nepal?

A patent protects a new and useful technical invention registered by the Department of Industry under the PDTA. It can cover how a machine, manufacturing method, device, material, or process works, while the registration certificate gives the owner rights for a renewable seven-year term.

A patent is not protection for every useful business idea. It is intended for a technical solution that can be described clearly enough for others in the field to understand and reproduce it. The law balances exclusive rights with disclosure: you seek protection, but the application must explain the invention.

That makes patents different from other industrial property rights. A trademark protects a wordmark, logo, TM, or business identity. An industrial design protects the visual appearance of a product. A patent protects function. A water-filter manufacturer may need a patent for a new filtration mechanism, a design registration for the bottle shape, and trademark registration for its brand.

Who can apply for patent registration Nepal?

An inventor, company, assignee, or foreign owner can apply to the Department of Industry, provided the applicant has the right to seek registration. Foreign applicants file through a Nepal-based agent or representative, while a seven-year patent term begins only after the DoI registers the patent.

Where a company owns the invention, the application should make that ownership clear. If an employee, consultant, or research partner created the invention, sort out assignment and ownership records before filing. A dispute over who owns the technical work can delay an otherwise sound application.

Foreign businesses should not assume that a foreign filing, foreign registration, or PCT application automatically protects them here. Nepal is not part of the Patent Cooperation Treaty (PCT). A direct national application at the DoI is required for patent protection in Nepal, although a Paris Convention priority claim may be relevant where the facts support it.

Can your invention be patented in Nepal?

The Department of Industry examines whether an invention is new and useful before publishing an accepted patent application under the PDTA. The invention should be a real technical solution, not merely a commercial proposal, broad ambition, or product name, and it must be described in workable technical detail.

Novelty means the invention should not already be publicly known through an earlier patent, published technical material, product, demonstration, or your own public disclosure. In practice, inventors often lose options by presenting a prototype at a trade fair, posting a detailed video, or sharing a document without confidentiality controls before filing.

Usefulness means the invention should have a practical application. A claim that only states a hoped-for result, without showing how that result is achieved, is weak. Before you invest in drafting, read our focused guide on what can be patented in Nepal and assess the invention honestly.

Do patents use NICE classes in Nepal?

Patent registration does not use the NICE Classification because NICE divides trademarks into 45 goods and service classes. Patent applications at the DoI are defined instead by the invention’s technical specification and claims, while trademark filings require one application for each relevant NICE class.

This distinction matters for startups. If you developed a solar-powered rice dryer, the patent application explains the dryer’s technical mechanism. Your product name and logo need separate trade mark protection in the relevant goods or service classes. Do not try to solve brand registration through a patent filing.

How do you register a patent with the DoI?

You register a patent by preparing the prescribed documents, filing them with the Department of Industry, completing examination, waiting through publication, and obtaining registration after any 35-day opposition period. The full route is governed by the PDTA and ends with a DoI registration certificate.

1. Assess the invention and preserve confidentiality. Identify the technical feature that makes the product or process different. Keep design files, test records, and development notes, but avoid public disclosure before filing.
2. Conduct a prior-art review. Prior art is earlier public technical knowledge. Search comparable patents, published documents, and products to identify what is already known and where your invention differs.
3. Draft the specification and claims. The specification gives the technical explanation. Claims are the numbered statements that define exactly what you want the patent to cover.
4. File the application and supporting documents. Submit the prescribed application, the technical papers, applicant details, and any supporting authority documents to the DoI.
5. Respond to examination issues. The DoI reviews whether the invention is new and useful. If concerns arise, respond carefully and only amend the scope with a clear technical basis.
6. Wait for publication and opposition. An accepted application is published for public information. An interested person may object within 35 days of publication.
7. Complete registration and plan renewals. If no valid objection blocks the application, the DoI registers the patent and issues the certificate. Record the renewal dates immediately.

A common mistake we see is treating the filing form as the main task. It is not. The technical description and claims usually decide whether the eventual right has practical value. Our patent registration team can help you assess, draft, file, and respond through the DoI process.

What documents are needed for a Nepal patent application?

A Nepal patent application needs the prescribed application form, a notarised Power of Attorney, and a specification with claims for examination by the Department of Industry. Priority or foreign patent documents may also be needed, and foreign applicants use a Nepal-based representative for the direct national filing.

Documents should match each other. The inventor name on the form, the ownership paperwork, and the technical papers should not tell different stories. If the applicant is not the inventor, explain the applicant’s right to file before the DoI asks for clarification.

How long does patent registration take in Nepal?

Patent registration in Nepal typically takes about 12–14 months where the application is unopposed, although a smooth straightforward matter may take around 6–8 months. Department of Industry examination, publication, the 35-day opposition window, and any technical reply determine the actual timing.

Complex inventions often take longer because the description must be checked carefully and objections may need a detailed response. An opposition can also add substantial time. Filing a well-organised application does not guarantee a fixed date, but it reduces avoidable delays caused by missing papers or unclear claims.

What affects patent registration cost in Nepal?

Patent registration costs depend on Department of Industry charges, technical drafting work, supporting documents, translations or notarisation, and the number of examination issues raised. The PDTA provides a seven-year term with renewals, so you should also plan for later renewal costs rather than focusing only on filing.

Drafting is often the major professional factor because claims must reflect the invention precisely. A simple mechanical improvement may need fewer drawings and narrower technical analysis than a complex manufacturing process. Opposition, amendments, ownership changes, and foreign priority material can also affect the overall work.

For a current estimate tailored to your invention, use the enquiry route rather than relying on an old public figure.

How long does a registered patent last in Nepal?

A registered patent lasts seven years in Nepal and may be renewed twice for additional seven-year periods, giving a maximum potential term of 21 years. The Department of Industry records the registration, while timely renewal keeps the patent right in force under the PDTA framework.

Do not treat the certificate as a permanent right. Put the registration date, ownership records, and renewal dates in a reliable calendar. If the inventor leaves the company, the company is sold, or ownership changes, deal with the record promptly so the DoI register remains accurate.

What mistakes can weaken a patent application?

The most damaging patent mistakes are public disclosure before filing, vague claims, missing ownership evidence, and assuming a foreign filing protects Nepal. These errors can affect novelty, delay Department of Industry examination, or leave the seven-year registered right narrower than the commercial invention you intended to protect.

• Sharing too much too early: Use confidentiality arrangements before pitching detailed technical information to manufacturers, investors, or suppliers.
• Writing only marketing language: “A better dryer” is not a patent specification. Explain components, steps, inputs, outputs, and the technical advantage.
• Confusing the invention with the product look: A distinctive casing or bottle may call for industrial design registration help as well as, or instead of, a patent.
• Waiting for overseas rights first: Nepal is outside the PCT, so include Nepal in your direct filing plan before entering the local market.
• Ignoring publication: Patent opposition is not the trademark 90-day window. For patents, the relevant public objection period is 35 days.

What does a practical Nepal patent example look like?

Imagine a Pokhara engineering startup develops a compact rice-husk briquette press that uses a new pressure-control arrangement to reduce blockages. The Department of Industry would examine the technical arrangement, while publication would allow a 35-day opposition period before potential registration.

The startup should first identify the exact mechanism it wants to protect: perhaps the pressure sensor placement, control sequence, and feed chamber relationship. It should document prototypes, check earlier technical publications, and prepare drawings that match the claims. Calling the device “Himal Press” does not itself patent the mechanism.

If the company also wants to protect “Himal Press” as its market-facing brand, it should make a separate trademark plan. The same business may own several rights, but each right protects a different asset and follows its own DoI process.

In short

Patent registration Nepal requires a direct application to the Department of Industry under the PDTA, careful technical drafting, examination, publication, and a 35-day opposition period. A registered patent runs for seven years and can be renewed twice, but its value depends heavily on filing early and defining the invention well.
