The DoI patent section Nepal handles patent and industrial-design filings under the Patent, Design and Trade Mark Act 1965. Expect examination, publication, opposition and registration at the Department of Industry, usually taking about 12–14 months when unopposed.
Key Takeaways
- The Department of Industry is Nepal’s registering authority for patents and industrial designs.
- Nepal follows first-to-file practice, so an early complete application matters.
- A patent protects how an invention works; an industrial design protects product appearance.
- Patent and design applications face separate 35-day opposition periods after publication.
- A patent lasts seven years and may be renewed twice, for a possible 21-year maximum.
- An industrial design lasts five years and is renewable under Nepalese practice.
- Foreign applicants need a Nepal-based agent or representative because Nepal is outside the PCT.
What does the DoI patent and design section do?
The DoI patent and design section receives, examines and registers patents and industrial designs in Nepal. It works within the Department of Industry, the government body responsible for industrial property administration. The governing statute is the Patent, Design and Trade Mark Act 1965, supported by departmental practice and the Industrial Property Bulletin.
People often call it the industrial design department of industry or the “DoI patent office.” These names usually refer to the same filing function. The Department also has a quasi-judicial role in industrial-property disputes. That means it can consider objections, hear parties and issue decisions within its legal authority.
You can review the Department of Industry’s official information, but public information may not answer every filing question. A practical application still needs the correct technical papers, ownership details and responses to examiner queries.
Who should file a patent or industrial design in Nepal?
Inventors, companies, research teams and product makers should file with the DoI before commercial disclosure. Nepal uses first-to-file practice: the earliest valid application generally has the stronger priority position. The applicant may be the inventor, a company, an assignee or a foreign owner acting through a Nepal-based representative.
Do not assume that being the first person to build or sell something automatically gives you a registered right. Public disclosure can also make novelty harder to establish. If your startup has developed a new water filter, machine part or manufacturing process, consider patent filing Nepal before launch, demonstrations or broad investor circulation.
Design filing suits a product whose commercial value lies in its appearance. Examples include the visual form of a lamp, furniture item, bottle, package or household appliance. If the key advantage is the product’s technical operation, a patent may be the better route. Some products may need both rights, filed separately.
What does a Nepal patent examiner assess?
A Nepal patent examiner assesses whether the invention is new and useful under the Act, while the application must explain its technical contribution clearly. Patent practice also considers novelty, inventive step and industrial applicability. The specification and claims give the examiner the working map for understanding and testing your invention.
Novelty means the invention is not already publicly known. An inventive step asks whether the solution is more than an obvious change for a skilled person in that field. Industrial applicability means it can be made or used in industry. Claims are the legal statements that define what you want protected.
The examiner may raise a query or objection. This does not always mean the application has failed. It may show that the description is unclear, the claims are too broad, or prior material creates a concern. A focused written response, supported by amendments where appropriate, can keep the application moving.
How do patents and designs differ at the DoI?
Patents protect an invention’s technical function, while industrial designs protect a product’s visual appearance. The DoI examines patents for new and useful subject matter and designs for novelty and originality. Their filing papers, opposition periods and renewable terms differ, so choosing the right right at the start matters.
| Point of comparison | Patent | Industrial design |
|---|---|---|
| Main protection | How an invention works | Shape, configuration, pattern or ornament |
| DoI examination focus | Newness, usefulness, inventive contribution and industrial use | Newness and originality of appearance |
| Opposition period | 35 days after publication | 35 days after publication |
| Initial term | Seven years | Five years |
| Renewal position | Renewable twice, subject to the applicable process | Renewable under Nepalese practice |
How does patent filing Nepal work from start to certificate?
Follow the DoI’s application sequence carefully: file first, answer examination issues, wait through publication and opposition, then complete registration. Patent filing Nepal is not finished when you submit papers. The certificate comes only after the Department accepts the application and the statutory steps are complete.
- Keep the invention confidential. Record the inventors, ownership and development history. Consider a prior-art search before disclosure.
- Prepare the application. Include the prescribed form, specification, claims, abstract and suitable technical drawings. The claims should match the description.
- File with the DoI. The Department records the application and filing details. That filing date is central in a first-to-file system.
- Answer examination queries. The Nepal patent examiner may ask for clarification or changes. Respond through the applicant or authorised agent.
- Wait for publication. If accepted for publication, the application appears in the Industrial Property Bulletin for public information.
- Handle opposition. An interested person may object within 35 days of publication. A dispute can require written submissions and a hearing.
- Complete registration. If the matter clears opposition, complete the Department’s registration requirements and receive the patent certificate.

How does the DoI register an industrial design?
The DoI registers an industrial design after checking its newness and originality, publishing it and allowing a 35-day objection period. A design application must show the appearance precisely through drawings or photographs. The Department is not protecting a purely technical function; that concern belongs in a patent application.
Prepare clear representations from the relevant views, such as plan, elevation and side views. Add a statement or description that identifies the design’s originality. A design that is already registered or publicly known in Nepal may face difficulty under the Act, including the design provisions around Sec. 14.
Do not publish packaging, furniture or a product prototype widely before filing. A realistic example is a Kathmandu startup developing a distinctive insulated lunch box. If its locking mechanism is inventive, the technical mechanism may support a patent. If its external form is distinctive, the appearance may support industrial design protection. The business should assess both before launch.
Which documents does the patent and design section need?
Applicants need the prescribed form and right-specific technical or visual documents. Patent files require a specification and claims; design files require clear representations and originality details. A Nepal-based agent normally files a notarised Power of Attorney, while foreign applicants may need certified priority or home-registration papers.
- Patent: application form, specification, claims, abstract, drawings where needed and Power of Attorney where an agent acts.
- Design: application form, design representations or photographs, relevant views, originality details and Power of Attorney where applicable.
- Priority claim: certified or notarised foreign filing evidence in English, if priority is claimed.
- Foreign ownership: certified or notarised home-country registration evidence where required for the filing.
- Company authority: ownership and authorisation records should match the applicant named in the form.
Names, dates and ownership should be consistent across every document. A mismatch can create a formal query before the examiner reaches the technical substance. The exact checklist may depend on the applicant and claim, so obtain a current review before filing.
How long does the Nepal patent process take?
The Nepal patent process typically takes about 12–14 months from filing to certificate when the application is unopposed. A straightforward file may finish in roughly 6–8 months, but that is the favourable end rather than the normal promise. Technical queries, amendments, publication delays or opposition can extend the period.
What determines the cost of filing at the DoI?
Filing cost depends on the right, application work, government charges, professional assistance and later events. Patent and design applications have different government-fee structures, while foreign filings may add agent, certification and translation work. A complex specification or opposition also requires more professional time than a simple file.
Do not judge the total by the initial application charge alone. You may need technical drafting, drawings, notarisation, certified copies, responses to objections, registration formalities and future renewals. Ask for a current estimate through IP Sewa’s contact team, or review the relevant tools before making a filing decision.
What happens after publication in the Industrial Property Bulletin?
Publication gives the public notice of the accepted patent or design application and starts the relevant opposition period. For patents and industrial designs, an interested person may object within 35 days. The DoI considers the objection and may withhold registration while the parties provide submissions or attend a hearing.
This is different from the 90-day trademark opposition practice often mentioned in Nepal. Do not copy a trademark deadline into a patent or design file. Track the exact publication entry, right type and deadline. IP Sewa provides staffed opposition and enforcement help, but it does not operate an automated public Bulletin alert service.
If you own a competing invention or copied product appearance, gather the Bulletin entry, earlier filing or registration evidence and technical or visual comparison. A timely objection is stronger than a late complaint after the certificate has issued.
What legal basis controls the DoI section?
The Patent, Design and Trade Mark Act 1965 supplies Nepal’s core statutory framework for patents, industrial designs and trademarks. Patent provisions include the patentability and registration rules around Sec. 4–7, while industrial-design rules include Sec. 14. The Department of Industry administers the Act and decides applications and objections within its authority.
The statute is old, but it remains the central law used for these filings. Nepal is also connected to international intellectual-property principles through instruments such as the Paris Convention and TRIPS. Nepal is not a member of the PCT, so a PCT filing does not itself grant Nepalese patent protection. A direct national filing is required.
For the statutory text and related legislation, consult the Nepal Law Commission’s legal materials. This article is general information, not legal advice. Technical claim scope, priority and opposition strategy should be reviewed for your facts.
Which mistakes delay patent and design applications?
Avoid weak claims, unclear drawings, premature disclosure and inconsistent ownership details. These errors make examination harder and can damage priority. The DoI patent section Nepal cannot repair a missing technical explanation or infer the scope of an invention from marketing material.
- Filing after disclosure: public demonstrations, sales or online posts may create a novelty problem.
- Writing a thin specification: explain the invention’s parts, operation and practical technical contribution.
- Overclaiming: claims broader than the description may attract an objection.
- Using poor design images: blurred or incomplete views do not define appearance well.
- Choosing the wrong right: a design does not protect a technical mechanism, and a patent does not protect every visual detail.
- Missing deadlines: opposition, response and renewal dates need active responsibility by the owner or agent.
- Assuming foreign protection travels automatically: Nepal requires a direct national route outside the PCT system.
Keep a single internal file containing the original drawings, inventor assignments, filing receipt, DoI correspondence and publication record. That simple habit helps your team answer questions quickly and prove what was filed.
What should you do before visiting the DoI patent section?
Prepare a confidential invention or design summary, confirm ownership, check earlier material and decide whether you need patent or design protection. Then assemble the correct papers and appoint a Nepal-based agent if required. Early preparation gives the DoI examiner a coherent file and protects your filing date.
For patents, explain the problem, solution, working method and technical variations. For designs, identify the visual features that make the product distinctive. Do not mix promotional language with legal scope. A product name or logo belongs to trademark protection, not automatically to a patent or design.
Businesses entering Nepal should also check whether a foreign filing supports a Paris Convention priority claim. That evidence must be filed in the required certified or notarised form. Foreign applicants should obtain local advice before assuming their home-country patent or design certificate is enough.
In short, what does the DoI patent section Nepal handle?
The Department of Industry receives patent and industrial-design applications, examines them, publishes accepted matters, considers opposition and issues certificates. Patent filing Nepal protects technical inventions for an initial seven-year term, renewable twice. Industrial design registration protects appearance for five years, renewable under local practice.
File before disclosure, use precise technical or visual documents, respect the 35-day opposition period and plan for a typical 12–14-month process. The right filing strategy depends on the invention, product, ownership and evidence available.
