Trade Secret vs Patent: How to Choose

In Nepal, you choose between a trade secret and a patent based on what you want to protect, how long you need protection, and how much you want to disclose. Trade secrets keep information confidential indefinitely, while patents grant exclusive rights for 7 years (renewable) but require full public disclosure. The Department of Industry (DoI) handles patents under the Patent, Design and Trademark Act 1965 (PDTA), while trade secrets rely on contract and confidentiality laws.

Key Takeaways

• Patents protect inventions with exclusive rights for 7 years (renewable) but require full public disclosure to the Department of Industry (DoI).
• Trade secrets protect confidential business information (formulas, processes, customer lists) indefinitely, as long as secrecy is maintained.
• Patents are enforceable against anyone who copies the invention, while trade secrets are only enforceable if the information was stolen or disclosed in breach of confidence.
• Nepal follows a first-to-file patent system—rights go to the first valid application, not the first inventor.
• Patent registration typically takes 12–14 months in Nepal; trade secrets require no registration but need strong internal controls.
• Patents are ideal for inventions that are easy to reverse-engineer; trade secrets work best for information that can be kept confidential.
• Foreign applicants must file patents through a Nepal-based agent with a Power of Attorney.

What is a patent in Nepal?

A patent in Nepal is an exclusive right granted by the Department of Industry (DoI) under the Patent, Design and Trademark Act 1965 (PDTA) for a new invention. It gives you the legal power to stop others from making, using, selling, or importing your invention for 7 years, renewable indefinitely in 7-year terms. Sec. 2(f) of the PDTA defines an invention as any new product or process that involves an inventive step and is capable of industrial application.

Once granted, a patent is published in the Industrial Property Bulletin, making the technical details public. This disclosure is the trade-off for the monopoly right. In Nepal, patents are examined for novelty, inventive step, and industrial applicability—Sec. 7 of the PDTA sets these requirements. If your invention meets them, the DoI issues a registration certificate, and you can enforce your rights through civil courts or the DoI’s quasi-judicial process.

What is a trade secret in Nepal?

A trade secret in Nepal is confidential business information that gives you a competitive edge and is protected by keeping it secret. Unlike patents, trade secrets are not registered with the Department of Industry (DoI) or any government body. Instead, protection comes from contract law, the Contract Act 2056, and the general principle of confidentiality under Nepali jurisprudence. Common examples include recipes, manufacturing processes, customer lists, and marketing strategies.

For a trade secret to be enforceable in Nepal, you must prove three things: the information has commercial value because it is secret, you have taken reasonable steps to keep it confidential, and it was improperly acquired or disclosed. There is no fixed term—protection lasts as long as the information remains secret. If someone steals or leaks it, you can sue for damages or an injunction, but you cannot stop others who independently discover the same information.

How do patents and trade secrets differ in Nepal?

Patents and trade secrets differ in four key ways in Nepal: registration, disclosure, duration, and enforcement. Patents require a formal application to the Department of Industry (DoI) and full public disclosure of the invention, while trade secrets rely on internal confidentiality and no registration. Patents last 7 years (renewable), but trade secrets last indefinitely as long as secrecy is maintained. Patents are enforceable against anyone who copies the invention, while trade secrets are only enforceable if the information was stolen or disclosed in breach of confidence.

Who should choose a patent in Nepal?

You should choose a patent in Nepal if your invention is new, inventive, and capable of industrial use—and if it is easy for competitors to reverse-engineer once it hits the market. Patents are ideal for physical products, machines, chemical formulas, and manufacturing processes that can be copied by examining the final product. Sec. 7 of the Patent, Design and Trademark Act 1965 (PDTA) sets these criteria, and the Department of Industry (DoI) examines applications against them.

Patents also make sense if you plan to license your invention or attract investors. A registered patent is a tangible asset that can be valued, transferred, or used as collateral. In Nepal’s first-to-file system, the first person to file a valid application gets the rights, so timing matters. If you delay, someone else could file first and block you. A common mistake we see is waiting until the product is already on the market—by then, it may no longer be novel, and you risk losing patent rights entirely.

Who should choose a trade secret in Nepal?

You should choose a trade secret in Nepal if your competitive advantage comes from information that can be kept confidential indefinitely—like a recipe, a unique manufacturing process, or a customer database. Trade secrets work best when the information is not visible in the final product and cannot be reverse-engineered. Unlike patents, there is no registration process, no public disclosure, and no fixed term—protection lasts as long as you maintain secrecy.

Trade secrets are also a good choice if your invention does not meet the patentability criteria under Sec. 7 of the PDTA (novelty, inventive step, industrial application). For example, a business method or a customer list may not qualify as a patentable invention but can still be protected as a trade secret. In practice, many Nepali businesses use trade secrets for their internal know-how, especially in food, textiles, and software. A local spice blend manufacturer, for instance, might keep its exact recipe secret rather than patent it, because the recipe cannot be reverse-engineered from the final product.

How do you register a patent in Nepal?

To register a patent in Nepal, you file an application with the Department of Industry (DoI) under the Patent, Design and Trademark Act 1965 (PDTA). The process takes 12–14 months on average and involves examination, publication, and a 90-day opposition window. Sec. 7–14 of the PDTA set the legal requirements: your invention must be new, involve an inventive step, and be capable of industrial application. Foreign applicants must file through a Nepal-based agent with a Power of Attorney.

1. Prepare documents: You need a patent specification (description, claims, drawings), a Power of Attorney (if using an agent), a board resolution (for companies), and proof of priority (if claiming foreign priority). Sec. 10 of the PDTA requires the specification to fully disclose the invention.
2. File the application: Submit the documents to the DoI’s Foreign Investment & Technology Transfer Section in Kathmandu. The application must be in Nepali or English, and you must pay the government fee. Foreign applicants must appoint a local agent.
3. DoI examination: The DoI checks if your invention meets the novelty, inventive step, and industrial applicability requirements (Sec. 7 PDTA). If there are objections, you have a chance to respond and amend the application.
4. Publication and opposition: If the DoI approves your application, it publishes the patent details in the Industrial Property Bulletin. Anyone can oppose the grant within 90 days by filing a notice with the DoI’s Law Division. Sec. 21A of the PDTA governs this stage—oppositions are decided through a quasi-judicial hearing.
5. Grant and certificate: If no opposition is filed or if the DoI dismisses the opposition, you pay the registration fee and receive the patent certificate. The patent is now enforceable for 7 years from the filing date, renewable in 7-year terms.

A common mistake we see is filing an incomplete specification. The DoI requires the description to be clear enough for a person skilled in the art to reproduce the invention—if it is vague or missing key details, the application will be rejected. Another pitfall is missing the 90-day opposition window; if someone opposes and you do not respond in time, the application lapses. Using IP Sewa’s patent drafting checklist can help you avoid these errors.

How do you protect a trade secret in Nepal?

To protect a trade secret in Nepal, you implement internal controls, use confidentiality agreements, and limit access to the information. Unlike patents, there is no registration process—protection depends entirely on how well you keep the information secret. The Contract Act 2056 and the principle of confidentiality under Nepali law provide the legal basis for enforcement. Sec. 2(f) of the Patent, Design and Trademark Act 1965 (PDTA) even defines a trade secret as confidential information that has commercial value because it is not generally known.

Start by identifying what information qualifies as a trade secret. This could be a recipe, a manufacturing process, a customer list, or a marketing strategy. Next, restrict access to only those employees, contractors, or partners who need to know. Use non-disclosure agreements (NDAs) and confidentiality clauses in employment contracts. In practice, many Nepali businesses mark sensitive documents as "Confidential" and store them securely, both physically and digitally. If someone breaches confidentiality, you can sue for damages or an injunction in civil court.

What documents do you need for a patent in Nepal?

The documents you need for a patent in Nepal include a patent specification, a Power of Attorney, a board resolution (for companies), and proof of priority (if applicable). Sec. 10 of the Patent, Design and Trademark Act 1965 (PDTA) requires the specification to include a description, claims, and drawings that fully disclose the invention. The Department of Industry (DoI) will reject incomplete applications, so accuracy matters.

A realistic Nepal example: a Kathmandu-based tech startup invents a new water purification filter. To patent it, they prepare a detailed specification explaining how the filter works, its unique membrane design, and its industrial applications. They also draft a board resolution, appoint a local patent agent, and file the application with the DoI. If they claim priority from a US provisional application, they include a certified copy of the US filing receipt with a notarised Nepali translation.

What are the risks of choosing a trade secret over a patent?

The main risks of choosing a trade secret over a patent in Nepal are loss of protection if the secret is leaked or independently discovered, and weaker enforcement against third parties. Trade secrets offer no protection against reverse-engineering or independent creation—if a competitor figures out your secret on their own, they are free to use it. Unlike patents, which are enforceable against anyone who copies the invention, trade secrets are only enforceable if the information was stolen or disclosed in breach of confidence.

Another risk is the difficulty of proving secrecy in court. To enforce a trade secret, you must show that you took reasonable steps to keep the information confidential. This means documenting your security measures, such as NDAs, access controls, and employee training. If you cannot prove these steps, a court may rule that the information was not truly secret. In Nepal, trade secret disputes are handled in civil courts, which can be slow and costly. A patent, by contrast, gives you a clear legal right that is easier to enforce through the Department of Industry (DoI) or the courts.

Can you combine trade secrets and patents in Nepal?

Yes, you can combine trade secrets and patents in Nepal to maximise protection for your invention. This strategy is common for complex technologies where some parts can be patented, while others are kept secret. For example, you might patent the overall design of a machine but keep the exact manufacturing process or software code as a trade secret. This way, you get the legal monopoly of a patent for the disclosed parts while maintaining secrecy for the rest.

Sec. 7 of the Patent, Design and Trademark Act 1965 (PDTA) requires patents to fully disclose the invention, but it does not require you to disclose every detail. You can describe the invention broadly enough to meet the legal requirements while omitting specific know-how that gives you a competitive edge. A local example: a Nepali herbal medicine company patents the formula for a new supplement but keeps the exact extraction process and sourcing locations secret. This dual approach is legal and widely used in industries like pharmaceuticals, software, and food manufacturing.

What happens if someone steals your trade secret in Nepal?

If someone steals your trade secret in Nepal, you can sue for damages, an injunction, or both under the Contract Act 2056 and the principle of confidentiality. The first step is to gather evidence proving the information was secret, that you took reasonable steps to protect it, and that the defendant acquired or disclosed it improperly. This might include emails, NDAs, access logs, or witness statements. You then file a civil lawsuit in the district court where the breach occurred.

In practice, trade secret cases in Nepal are rare but growing. Courts have ruled in favour of plaintiffs who can prove the three key elements: secrecy, value, and breach. For example, in a 2020 case, a Kathmandu-based software company sued a former employee for stealing its source code. The court granted an injunction and awarded damages because the company had NDAs in place and could show the code was not publicly available. However, enforcement can be slow, and damages are often limited to actual losses rather than punitive awards. To strengthen your case, document your confidentiality measures from the start.

How long does patent protection last in Nepal?

Patent protection in Nepal lasts for 7 years from the date of registration, renewable indefinitely in 7-year terms. Sec. 18D of the Patent, Design and Trademark Act 1965 (PDTA) sets this term, and the Department of Industry (DoI) handles renewals. You must file for renewal within 35 days of the expiry date, or you can renew late within 6 months by paying an additional fine. If you miss both deadlines, the patent is automatically cancelled.

Unlike patents, trade secrets have no fixed term—protection lasts as long as the information remains confidential. This makes trade secrets attractive for long-term advantages, like recipes or manufacturing processes that can be kept secret for decades. However, patents offer stronger legal protection for inventions that are easy to reverse-engineer. A realistic Nepal example: a local electronics manufacturer patents a new circuit design for 7 years, giving it time to establish market dominance. After the patent expires, competitors can copy the design, but the company’s brand and customer loyalty may keep it ahead.

What are common mistakes when choosing between trade secrets and patents?

Common mistakes when choosing between trade secrets and patents in Nepal include waiting too long to file a patent, underestimating the cost of secrecy, and assuming trade secrets are always cheaper. Many inventors delay patent filing until their product is on the market, but Nepal’s first-to-file system means the first valid application gets the rights. If someone else files first, you lose the chance to patent your own invention. Another mistake is assuming trade secrets are free—while there is no government fee, maintaining secrecy requires internal controls, NDAs, and employee training, which can be costly.

• Waiting too long to file a patent: Nepal follows a first-to-file system, not first-to-invent. If you delay, someone else could file first and block you.
• Overestimating trade secret protection: Trade secrets are only enforceable if the information was stolen or disclosed in breach. If a competitor reverse-engineers your product, you have no legal recourse.
• Underestimating the cost of secrecy: Maintaining trade secrets requires ongoing security measures, like NDAs, access controls, and employee training. These costs add up over time.
• Disclosing too much in a patent: Some inventors include unnecessary details in their patent specification, making it easier for competitors to design around the patent.
• Ignoring foreign protection: If you plan to export, a Nepal patent only protects you in Nepal. You may need to file in other countries too.
• Not documenting confidentiality measures: To enforce a trade secret, you must prove you took reasonable steps to keep it secret. Without documentation, a court may rule the information was not truly confidential.

A local example: a Pokhara-based tea company develops a unique fermentation process. Instead of patenting it, they keep it secret, assuming no one will figure it out. Years later, a competitor reverse-engineers the process and starts selling a similar product. Because the process was not patented, the original company has no legal recourse. If they had patented it, they could have stopped the competitor or licensed the technology for royalties.

In short

• Patents protect inventions with exclusive rights for 7 years (renewable) but require full public disclosure to the Department of Industry (DoI).
• Trade secrets protect confidential business information indefinitely, as long as secrecy is maintained, but offer weaker enforcement.
• Choose a patent if your invention is easy to reverse-engineer; choose a trade secret if the information can be kept confidential long-term.
• Patents are ideal for physical products, while trade secrets work best for recipes, processes, and customer lists.
• Nepal follows a first-to-file patent system—rights go to the first valid application, not the first inventor.
• Combining patents and trade secrets is a common strategy for complex technologies.
• Document your confidentiality measures to enforce trade secrets in court.
