Patent novelty vs inventive step determines registrability under Nepal’s Patent, Design and Trademark Act 1965. The Department of Industry (DoI) examines whether an invention is new and useful, requiring absolute novelty plus a technical advance beyond existing knowledge to grant a seven-year renewable term.
Key Takeaways
- Nepal requires both absolute novelty and a technical inventive step for patent registration under Sec. 3 of the PDTA 1965.
- The Department of Industry examines applications to ensure inventions are "new and useful" before publication in the Industrial Property Bulletin.
- Novelty means the invention has never been disclosed publicly anywhere; inventive step means it is not obvious to a skilled person.
- Patents in Nepal are valid for seven years and renewable twice, totaling a maximum protection period of 21 years.
- Foreign applicants must file directly through a local agent because Nepal is not part of the PCT or Madrid System.
- A prior art search is critical since even minor public disclosures before filing can destroy novelty permanently.
- Professional drafting helps articulate the inventive step clearly to satisfy DoI examiners during substantive review.
What is the difference between patent novelty and inventive step?
Patent novelty vs inventive step represents two separate hurdles under Sec. 3 of the Patent, Design and Trademark Act 1965. Novelty asks if the invention already exists in the public domain anywhere, while inventive step asks if the improvement would be obvious to someone skilled in that technical field. Both conditions must be satisfied simultaneously for the Department of Industry to register a patent.
In practice, novelty is a binary yes-or-no test based on prior art. If a journal article, product manual, or social media post described your exact solution before your filing date, novelty fails immediately. Inventive step is more subjective; it evaluates the quality of the technical leap. A mere change in size, material, or arrangement usually lacks this step unless it produces an unexpected result or solves a long-standing problem in a way experts did not anticipate.
How does the Department of Industry examine patentability?
The Department of Industry examines patent applications to determine if they are "new and useful" as mandated by the PDTA 1965. Examiners review the specification and claims against available prior art and assess whether the described invention demonstrates sufficient technical advancement over existing knowledge. This substantive examination occurs before the application proceeds to publication in the Industrial Property Bulletin.
Unlike trademark examination which focuses on visual or phonetic similarity, patent examination digs into technical substance. The examiner reads your claims to understand the scope of protection sought. They then compare those claims against known technologies. If the examiner finds the invention lacks novelty or an inventive step, they issue an objection. You must respond with arguments or amendments to overcome these refusals, often requiring technical and legal expertise to frame the invention’s unique contribution persuasively.
Which documents prove novelty and inventive step?
Proving patent novelty vs inventive step relies entirely on the specification and claims submitted with your application. The specification must describe the invention clearly enough for a skilled person to replicate it, while the claims define the precise legal boundaries of protection. Supporting drawings, diagrams, and experimental data help demonstrate the technical problem solved and the non-obvious nature of the solution to DoI examiners.
For foreign applicants claiming priority under the Paris Convention, a certified copy of the original foreign filing receipt or registration certificate serves as evidence of an earlier date. This earlier date becomes your effective filing date in Nepal for novelty purposes. Without proper documentation, you lose the benefit of that earlier date, potentially exposing your invention to intervening disclosures that could destroy novelty. Our team can help you prepare these documents correctly through our patent registration service.
Why does prior art destroy novelty instantly?
Prior art destroys novelty because Nepal follows an absolute novelty standard where any public disclosure before filing invalidates patent rights. This includes publications, public use, sales, exhibitions, or online posts anywhere in the world. Even disclosing your own invention at a trade fair or in a research paper before filing counts as prior art against yourself, permanently barring registration regardless of who made the disclosure.
This strict approach differs from some jurisdictions offering grace periods for inventor disclosures. Nepal provides no such safety net under current law. Once information enters the public domain, it becomes part of the state of the art. This reality makes confidential handling essential during development. Non-disclosure agreements with partners, employees, and contractors are vital protective measures before you file. Running a professional search using our conflict checker tool adapted for patents can identify risky disclosures early.
How do you establish a non-obvious inventive step?
Establishing an inventive step requires articulating the specific technical problem your invention solves and explaining why existing solutions failed. You must show that the chosen approach was not a logical next step for practitioners in the field. Evidence of unexpected results, commercial success tied to technical features, or overcoming longstanding industry prejudice strengthens this argument significantly during DoI examination.
Drafting plays a crucial role here. Vague descriptions like "improved efficiency" rarely suffice. Instead, quantify the improvement and link it directly to structural or procedural changes. Explain what alternatives existed and why they were inadequate. This narrative transforms abstract claims into concrete technical contributions. Professional drafters understand how to structure specifications to highlight these distinctions effectively, reducing refusal risk.

| Factor | Novelty Assessment | Inventive Step Assessment |
|---|---|---|
| Core Question | Has this exact thing existed before? | Would this solution be obvious to try? |
| Evidence Type | Prior art documents, products, uses | Technical reasoning, comparative data |
| Standard | Binary: identical or not | Judgmental: degree of advancement |
| Failure Cause | Single anticipatory reference | Combination of references suggesting solution |
| Remedy | Narrow claims to avoid prior art | Emphasize unexpected technical effect |
What happens if novelty or inventive step fails?
If novelty or inventive step fails during examination, the Department of Industry issues a refusal notice detailing the grounds. You receive an opportunity to respond with arguments, claim amendments, or additional evidence within a specified timeframe. Successful responses often involve narrowing claim scope to exclude prior art or providing detailed technical explanations demonstrating non-obviousness that the initial application lacked.
Persistent failure leads to final rejection. At this stage, administrative appeal options exist but are limited and costly. Prevention through thorough pre-filing searches and robust drafting proves far more economical than fighting rejections. Many applicants underestimate how narrowly examiners interpret "obviousness." What seems innovative to an inventor may appear routine to a specialist reviewer. Engaging experienced counsel early mitigates this gap between perception and legal reality.
How does Nepal's first-to-file system affect novelty?
Nepal’s first-to-file system makes filing speed critical for preserving novelty because rights belong to whoever submits a valid application first, not whoever invented first. Delaying filing while perfecting prototypes or seeking funding risks another party filing independently or accidentally disclosing similar technology. Your filing date establishes the cutoff point for evaluating novelty against all subsequent disclosures.
This system also means provisional applications or informal disclosures offer no protection. Only a complete application with adequate specification secures a priority date. International applicants should note Nepal is outside the Patent Cooperation Treaty (PCT), so there is no centralized international filing route covering Nepal. Direct national filing through a local representative remains mandatory. For strategic timing advice, visit our contact page to discuss your situation.
Can industrial designs rely on novelty alone?
Industrial design registration in Nepal relies primarily on novelty and originality rather than inventive step, distinguishing it fundamentally from patent protection. Under the PDTA 1965, a design must be new and original in its visual appearance—shape, configuration, pattern, or ornament—to qualify. Functional improvements or technical advancements fall outside design protection and require patent filing instead if they meet inventive step criteria.
This distinction matters because many creators confuse aesthetic uniqueness with technical innovation. A beautifully shaped water bottle may deserve design registration for its form, but if its shape also improves grip ergonomics through novel engineering, that functional aspect needs patent coverage. Relying solely on design protection leaves technical innovations vulnerable to copying. Understanding which right applies prevents costly gaps. Explore the differences further in our article comparing industrial design vs patent in Nepal.
In short, mastering patent novelty vs inventive step is essential for securing enforceable rights in Nepal. Novelty demands absolute newness free from any prior disclosure, while inventive step requires demonstrating non-obvious technical progress beyond existing knowledge. Both tests operate under the PDTA 1965 framework administered by the Department of Industry, with seven-year renewable terms rewarding successful applicants. Thorough preparation, professional drafting, and strategic filing timing maximize approval chances in this first-to-file jurisdiction.
