The Patent, Design and Trademark Act, 2022 (1965) (PDTA) is Nepal's foundational intellectual property law governing patents. Section 2(a) defines a patent as "any useful invention relating to a new method of process or manufacture, operation or transmission of any material or combination of materials, or that made on the basis of a new theory or formula."
Key Statutory Requirements for Patentability:
| Criterion | Description | Assessment Standard |
|---|---|---|
| Novelty | Invention must be new, not anticipated by prior art | Absolute novelty—no prior public disclosure |
| Inventive Step | Must involve non-obvious advancement over existing technology | Clear difference from state of the art |
| Industrial Applicability | Must be capable of practical application for utility | Demonstrable practical use |
Nepal is a member of two critical international IP conventions:
| Convention | Membership Date | Key Benefit for Nepali Inventors |
|---|---|---|
| Paris Convention for Protection of Industrial Property, 1883 | June 22, 2001 | 12-month priority period for foreign filings |
| TRIPS Agreement, 1995 | WTO member obligations | Minimum IP protection standards |
Critical Limitation: Nepal is not a member of the Patent Cooperation Treaty (PCT). This significantly impacts international filing strategies, requiring direct national filings in target countries rather than centralized PCT applications.
Phase 1: Pre-Filing Preparation
Step 1: Prior Art Search
Conduct comprehensive patentability search before filing:
Step 2: Invention Documentation
Prepare detailed technical documentation:
| Document | Content Requirements |

| Proof of Inventor Identity | Citizenship certificate, passport |
| Assignment Deed | If applicant is not inventor |
Filing Fee: NPR 5,000 (application fee) + NPR 35,000 (registration fee upon grant)
Step 5: Formal Examination (2-4 months)
DOI conducts formality examination:
Deficiency Correction: If documents incomplete, DOI issues invitation to correct with specified timeline.
Phase 3: Substantive Examination
Step 6: Patentability Investigation (6-18 months)
DOI substantive examination assesses:
Step 7: Publication
Upon passing substantive examination:
Phase 4: Opposition and Grant
Step 8: Opposition Period (35 days)
Third parties may file opposition if:
DOI investigates complaints and decides validity.
Step 9: Patent Grant
If no successful opposition:
Total Timeline: 18-36 months from filing to grant (variable based on complexity and workload)
| Period | Duration | Renewal Fee |
|---|---|---|
| Initial term | 7 years from registration | NPR 35,000 (NPR 5,000/year) |
| First renewal | Additional 7 years (total 14 years) | NPR 52,500 (NPR 7,500/year) |
| Second renewal | Final 7 years (total 21 years) | NPR 52,500 (NPR 7,500/year) |
| Maximum protection | 21 years total | — |
Grace Period: 35 days after expiry for renewal without penalty; 6 months with NPR 1,000 penalty; thereafter cancellation.
12-Month Priority Window:
Since Nepal is a Paris Convention member, Nepali inventors can:
Strategic Considerations:
| Approach | Advantages | Disadvantages |
|---|---|---|
| Nepal first, foreign within 12 months | Establishes early priority; lower initial cost | Delayed foreign protection; translation requirements |
| Simultaneous multi-country filing | Immediate broad protection | High initial cost; complex coordination |
| Foreign first (if resident abroad) | Access to PCT in some cases | Loss of Nepal priority if not careful |
Nepal's Non-PCT Status Implications:
| Market | Rationale | Filing Route |
|---|---|---|
| India | Largest neighbor, manufacturing hub, similar technical fields | Direct national filing at Indian Patent Office |
| United States | Large market, strong enforcement, licensing opportunities | Direct USPTO filing or provisional application |
| China | Manufacturing center, growing innovation market | Direct CNIPA filing |
| European Union | EP validation for multiple countries | Direct EPO filing |
| ASEAN countries | Regional trade, manufacturing partnerships | Individual national filings |
Estimated Costs for International Protection:
| Jurisdiction | Filing Cost (USD) | Prosecution Cost (USD) | Total (Approx.) |
|---|---|---|---|
| India | $200-400 | $1,000-3,000 | $1,500-3,500 |
| United States | $300-1,600 | $3,000-10,000 | $4,000-12,000 |
| China | $200-500 | $2,000-5,000 | $2,500-5,500 |
| Europe (EPO) | $4,000-6,000 | $5,000-15,000 | $10,000-25,000 |
| Multiple countries | Variable | Variable | $50,000+ for 5+ jurisdictions |
Note: Costs exclude translation, attorney fees, and maintenance fees.
| Scenario | Recommended Approach |
|---|---|
| Competitive technology field | File Nepal application immediately; foreign filings within 12 months |
| Limited budget | Focus on key markets (India, US); defer other jurisdictions |
| Potential licensing | File in major markets to enhance valuation; consider provisional US filing |
| Manufacturing partnership | File in partner's jurisdiction; consider trade secret for process innovations |
| Long development timeline | Use priority year for market validation; file foreign only if commercial interest confirmed |
Patentable Subject Matter in Nepal:
| Category | Examples | Considerations |
|---|---|---|
| Process patents | Manufacturing methods, chemical processes, software-implemented methods | Strong protection; easier to detect infringement |
| Product patents | Mechanical devices, compositions, apparatus | Clear scope; may require design patent complement |
| Use patents | New uses of known substances | Limited scope; consider method claims instead |
Excluded Subject Matter:
Post-Grant Strategy:
| Option | Implementation |
|---|---|
| Direct commercialization | Manufacture and market patented product/process |
| Licensing | Exclusive or non-exclusive licenses to third parties |
| Assignment | Sale of patent rights for lump sum or royalties |
| Cross-licensing | Exchange of patent rights with complementary technology holders |
| Enforcement | Litigation against infringers; border enforcement for imports |
Infringement Remedies:
The Secured Transactions Bill, 2023 (enacted 2025) allows intellectual property-backed loans for the first time in Nepal. Patents can now serve as collateral for financing, creating new commercialization pathways for inventors.
Key objectives include:
Patent registration Nepal typically requires 18-36 months from filing to grant: 2-4 months for formal examination, 6-18 months for substantive examination, 35-day publication and opposition period, and final grant processing. Complex applications or opposition proceedings may extend timelines.
Patent registration cost Nepal includes: NPR 5,000 application fee, NPR 35,000 registration fee (upon grant), and annual maintenance fees (NPR 5,000-7,500/year). Professional fees for patent agent/attorney services range NPR 25,000-100,000 depending on complexity.
No, Nepal is not a PCT member. Nepali inventors cannot file PCT international applications. International protection requires direct national filings in target countries, preferably within 12 months of Nepalese priority filing under Paris Convention.
A provisional specification establishes early priority date with brief invention description (used in some countries, not standard in Nepal). A complete specification is the full, enabling disclosure required for Nepalese patent grant, including detailed description, claims, and drawings.
Pre-filing protection strategies: Maintain invention confidentiality through non-disclosure agreements (NDAs), document invention development with dated records, conduct prior art search to assess patentability, and file promptly to secure priority date. Avoid public disclosure before filing.
Yes, foreign inventors can file patents in Nepal through the Paris Convention route (claiming priority from home country filing) or as first filing in Nepal. A local agent/attorney with DOI power of attorney is required for foreign applicants.
Patent infringement remedies Nepal include: civil suit for injunction and damages in District Court, criminal complaint for willful infringement (fine up to NPR 100,000 or imprisonment up to 1 year), and border enforcement for imported infringing goods. Evidence of infringement and patent validity required.
Software patents Nepal are possible if the invention demonstrates technical effect or industrial applicability beyond mere algorithm or business method. Software-implemented methods with concrete technical application (e.g., industrial process control, telecommunications) may be patentable; abstract software per se is generally excluded.
Yes, patent licensing Nepal is permitted through voluntary licensing agreements. Exclusive or non-exclusive licenses must be recorded with DOI for enforceability against third parties. Compulsory licensing available in limited circumstances (public health emergencies, anti-competitive practices).
Patent renewal grace period Nepal: 35 days after expiry without penalty; 6 months with NPR 1,000 penalty; thereafter cancellation. Lapsed patents cannot be revived; new application required subject to novelty requirements.
