If you’ve created a new product, process, or technical improvement, the first question is simple but critical: Is it patentable in Nepal? Understanding what qualifies as a patent and what does not can save inventors time, money, and disappointment. This article explains patentability in Nepal, the legal criteria, what can and cannot be patented, and real-world examples to help you decide the right protection strategy.
Legal Basis of Patentability in Nepal
Patents in Nepal are governed by the Patent, Design and Trade Mark Act, 2022 (1965 AD) and administered by the Department of Industry (DOI).
Under Nepalese law, a patent may be granted for an invention that:
Is new
Is useful
Is based on a new principle, formula, or method
Is not contrary to public interest or morality
Core Patentability Criteria Explained
1. Novelty (Must Be New)
An invention must be new in Nepal at the time of filing.
Not novel if:
Already published anywhere (papers, blogs, videos)
Already sold or publicly used
Previously registered or disclosed
Novel if:
No identical invention is publicly known
No prior patent or publication exists
Example:
✔ A new water-filtration mechanism designed for rural Nepal
✖ A known filter design already sold internationally
2. Usefulness (Industrial Applicability)
The invention must have practical use and provide real benefit.
Not useful:
Pure theories
Abstract ideas without implementation
Useful:
Can be manufactured or applied
Solves a real technical problem
Example:
✔ A low-energy grain-drying machine
✖ A vague “idea” to improve efficiency without technical details
3. Technical Nature (Not Just an Idea)
Nepalese patent law protects technical inventions, not ideas alone.
Protectable:
Processes
Machines
Technical systems
Chemical compositions (subject to regulation)
Not protectable:
Business ideas
Marketing concepts
A mere discovery without application
What CAN Be Patented in Nepal (with Examples)
1. Products & Devices
Mechanical tools
Machines
Equipment
Hardware innovations
Example:
✔ A hand-operated medical device for remote clinics
2. Processes & Methods
Manufacturing methods
Treatment or processing techniques
Technical workflows
Example:
✔ A new method for producing herbal extracts with higher stability
3. Improvements to Existing Products
Even if something exists, a technical improvement may be patentable.
Example:
✔ A redesigned cookstove that reduces fuel use by 30%
✖ A cosmetic shape change (this fits industrial design instead)
4. Chemical & Pharmaceutical Inventions (With Extra Caution)
New formulations
Improved compositions
Safer or more effective delivery systems
⚠ Must comply with health and regulatory standards.
Example:
✔ A novel drug-delivery composition
✖ A known drug with no technical modification
5. Foreign Inventions (Through Priority Claims)
Nepal is a member of the Paris Convention, allowing inventors to claim priority from earlier foreign filings (within 12 months).
Nepal is not a PCT member, so direct filing is required.

What CANNOT Be Patented in Nepal
❌ Discoveries (Without Application)
Natural phenomena
Scientific discoveries without technical use
Example:
✖ Discovering a plant property without a defined process or use
❌ Abstract Ideas & Theories
Mathematical formulas
Scientific principles
Mental methods
❌ Business Methods & Schemes
Pricing strategies
Financial models
App business logic without technical innovation
These may qualify for trade secrets, not patents.
❌ Designs Based Only on Appearance
If the invention is about shape, pattern, or ornamentation, it falls under industrial design, not patent.
❌ Inventions Against Public Order or Morality
Harmful technologies
Illegal or unethical applications
Patent vs Other IP Rights (Quick Comparison)
| IP Type | Protects | Example |
|---|---|---|
| Patent | Technical inventions | New machine, process |
| Industrial Design | Visual appearance | Bottle shape |
| Trademark | Brand identity | Product name/logo |
| Copyright | Creative works | Software code text |
Common Mistakes Inventors Make
Filing after public disclosure
Trying to patent an idea without technical detail
Choosing patent when design protection is appropriate
Weak specifications and claims
Ignoring renewal deadlines
How to Decide If Your Invention Is Patentable (Checklist)
✔ Is it new?
✔ Does it solve a technical problem?
✔ Can it be practically used or manufactured?
✔ Is it more than an idea or design change?
✔ Is it legally acceptable and ethical?
If most answers are “yes,” patent protection may be possible.
