Patent Assignment Agreement: Template (Nepal)

A patent assignment agreement in Nepal transfers ownership of a granted patent from an assignor to an assignee. The Department of Industry (DoI) records the change under the Patent, Design and Trade Mark Act 1965. A careful agreement and recordal protect the new owner’s position.

Key Takeaways

A patent assignment changes the registered owner, while a licence only permits use. Nepal’s Department of Industry handles the recordal under the Patent, Design and Trade Mark Act 1965. The safest approach identifies the patent precisely, proves the assignor’s title, and confirms the current DoI document checklist before filing.

• A patent assignment is a transfer of ownership, not simply permission to use an invention.
• The DoI should record the transfer so the register reflects the new patent owner.
• The agreement should identify the patent number, title, parties, rights transferred, and effective date.
• Check the patent’s status, expiry, renewals, licences, security interests, and earlier transfers before signing.
• A pending application is not the same as a granted patent; confirm the correct DoI procedure before treating it as an assignment.
• Foreign parties generally need a Nepal-based agent or representative for direct national filings and recordal work.
• Government charges and professional fees depend on the filing and documents; obtain a current figure from the IP Sewa team.

What is a patent assignment agreement in Nepal?

A patent assignment agreement is a written contract in which the current patent owner transfers identified rights to another person or entity. The current owner is the assignor. The recipient is the assignee. After completion and DoI recordal, the assignee can hold, use, license, renew, sell, or enforce the patent as its owner.

The transfer may be a sale, a contribution to a company, a gift, or part of a business transaction. The document should say whether it transfers the entire patent or only a legally separable interest. A vague sentence such as “all technology is transferred” may not clearly transfer a particular Nepal patent.

Do not confuse an assignment with a licence. A licence gives another party permission to make, use, sell, or commercialise an invention under agreed limits. Ownership stays with the licensor. An assignment changes ownership. If a founder wants a company to own the patent, a licence may not solve the problem.

Why does a patent ownership change need DoI recordal?

The Department of Industry administers Nepal’s patent register and handles patent ownership records. Recording a transfer gives the register an accurate public ownership position and supports later dealings, including licensing, renewal, enforcement, financing, or another sale. The written contract remains central, but the register should not be left outdated.

Recordal also helps third parties understand who may act for the patent. A buyer, lender, investor, or business partner will usually want to see the patent certificate and the assignment trail. If the patent remains in an inventor’s name, the company may face questions about authority, title, or the right to bring an enforcement claim.

DoI practice can depend on the patent file and the parties involved. That is why a current document review matters more than copying a foreign template. The Department of Industry’s official information is a useful starting point, but it may not answer every recordal question.

What law governs patent transfer in Nepal?

The Patent, Design and Trade Mark Act 1965 governs patent rights and transfers in Nepal. Sec. 21D addresses transfer of ownership and the need to submit the transfer to the Department of Industry. The Act is Nepal’s main statute for patents, industrial designs, and trademarks, so a patent assignment must be handled under this local framework.

Nepal’s treaty commitments, including TRIPS and the Paris Convention, do not replace the national recordal process. Nepal is not part of the PCT system for international patent applications. A foreign owner seeking a Nepal patent right must use the national route, and a foreign party changing ownership should obtain Nepal-specific advice.

Read the statutory framework through the Nepal Law Commission’s legal resources. This article is general information, not legal advice. The agreement should be reviewed against the patent file, the transaction, and the parties’ home-country signing rules.

Who can assign or receive a Nepal patent?

A registered patent owner can generally assign the patent to an individual, company, institution, or other eligible recipient, subject to title and DoI requirements. The assignor must have authority to transfer it. The assignee should have a clear legal identity and a practical ability to hold and manage the Nepal right.

Common transactions include an inventor assigning to a startup, a parent company transferring a patent to its Nepal subsidiary, or a buyer acquiring selected intellectual property in an asset purchase. A university, research organisation, or employer may also be involved. Each situation needs a careful chain-of-title check.

For a foreign assignee, Nepal does not provide automatic coverage through Madrid or PCT systems. Patent recordal is a direct Nepal matter. A Nepal-based agent or representative can prepare and submit the filing, communicate with the DoI, and deal with requests for clarification.

What should a Nepal patent assignment agreement contain?

A useful patent assignment agreement identifies the right, parties, consideration, transferred interests, warranties, and filing duties. Nepal does not require a universal commercial template for every transaction. The document should therefore be tailored to the patent certificate, the transaction structure, and the evidence the DoI may request.

1. Name the parties precisely: use full legal names, addresses, registration details, and authorised signatories.
2. Identify the patent: state the patent number, invention title, grant or registration details, and certificate reference.
3. Describe the transfer: say clearly whether all ownership, title, interest, benefits, and associated rights are assigned.
4. State the effective date: distinguish the date the parties sign from the date the DoI records the change.
5. Set out consideration: describe the commercial exchange or other basis of transfer without leaving the clause uncertain.
6. Address existing interests: disclose licences, security interests, co-owners, options, disputes, or restrictions.
7. Include title warranties: the assignor should confirm authority and disclose facts that could affect ownership or validity.
8. Allocate filing duties: state who prepares the application, supplies documents, pays charges, and answers DoI queries.
9. Add further-assurance wording: require reasonable cooperation if another signature or supporting document is needed.
10. Execute correctly: use suitable witnesses, certification, notarisation, and corporate approvals for the parties involved.

A template is a drafting aid, not proof of ownership. It cannot replace checking the patent certificate or the assignor’s earlier agreements. If an employee created the invention, review employment and invention-assignment documents too. The person signing the deed must have the right to transfer what the deed promises.

Can you assign a pending patent application in Nepal?

A pending application and a granted patent are different records, so you should not use a granted-patent assignment template without checking the DoI procedure. Nepal-specific treatment can depend on the application file, applicant details, and requested change. Ask the DoI or a Nepal agent before signing a transfer of a pending application.

The agreement should accurately describe the asset as either a pending application or a granted patent. It should not call an application a “registered patent”. Include its application number, filing date, title, applicant name, and any priority information where relevant.

For granted rights, obtain the certificate and verify that renewal obligations are current. A patent is valid for seven years and may be renewed twice for additional seven-year periods, subject to the statutory framework. A transfer cannot sensibly protect a right that has already expired or been cancelled.

How do you record a patent assignment with the DoI?

Parties record a Nepal patent transfer by submitting the signed assignment and supporting evidence to the Department of Industry. The DoI reviews the request against its file and administrative requirements. The applicant or Nepal-based representative must respond to any query before the ownership change is entered or endorsed.

1. Review the patent file: confirm the owner, patent number, status, expiry, renewals, inventors, co-owners, and recorded interests.
2. Prepare the agreement: tailor the deed to the transaction and identify the exact Nepal patent or application.
3. Approve and sign: obtain board or other authority approvals, then complete witnessing, certification, and notarisation as appropriate.
4. Prepare the DoI request: include the recordal application or request, agent authorisation, and supporting corporate or identity documents.
5. Submit the file: file through the assignee, assignor, or authorised Nepal representative using the current DoI process.
6. Answer queries: provide clarification or corrected documents if the Department asks about title, signatures, identity, or the patent.
7. Collect proof of recordal: keep the endorsement, confirmation, or updated certificate with the signed agreement and transaction records.

Which documents does the DoI usually need?

The supporting file usually includes the signed assignment instrument, patent certificate, identity or company records, and authority for any representative. Exact requirements can vary by transaction. A complete, consistent file reduces queries, especially where the assignor is foreign, the patent has co-owners, or the ownership chain is complex.

• Signed assignment agreement or deed, prepared for the identified patent.
• Patent registration certificate or certified copy from the existing file.
• DoI application or request for recording the ownership change.
• Power of Attorney for a Nepal-based agent, where one is used.
• Company registration and authorised board or management approval, where a company signs.
• Citizenship or identity evidence for individual parties, where requested.
• Foreign incorporation or authority documents, with suitable certification and translation where needed.
• Evidence explaining any earlier assignment, merger, name change, licence, or security interest.

Do not assume that an English document, scanned signature, or foreign notarisation will always be enough. Ask for the current DoI checklist before execution. Correcting a deed after signing can be slower than preparing the right version at the start.

How long does a DoI patent assignment take?

Nepal does not provide a universal statutory deadline for every patent recordal request. Timing depends on document readiness, DoI review, identity checks, title questions, and responses to queries. Preparation may take days or weeks, while administrative recordal may take longer when the file needs clarification.

It would be unsafe to promise a fixed four-to-eight-week result for every case. Build time for negotiation, signing, notarisation, translation, corporate approvals, filing, and follow-up. A foreign signatory may add practical delay. Ask for a case-specific estimate after the documents and patent record are reviewed.

What are the cost factors for a patent transfer in Nepal?

The total cost of a patent assignment has government charges and professional costs. Government charges depend on the requested recordal and any related amendment. Professional costs depend on title checking, drafting, translation, foreign documents, corporate approvals, negotiation, and responses to DoI queries.

There is no single evergreen figure for every DoI patent assignment. A simple transfer between one inventor and one Nepali company differs from a portfolio transfer involving several patents, co-owners, or an acquisition. Use the IP Sewa tools for general preparation and contact the team for a current assignment-specific assessment.

What mistakes weaken a patent assignment in Nepal?

Most assignment problems arise from unclear ownership, incomplete identification, or a mismatch between the agreement and the DoI record. Avoiding these errors protects the transaction and makes later licensing or enforcement easier. The assignee should review the patent before signing, not only after the purchase is complete.

• Using a generic foreign template that does not identify the Nepal patent or DoI record.
• Calling a licence an assignment, or transferring technology without transferring the patent itself.
• Ignoring co-owners, inventors’ agreements, earlier assignments, licences, or lender interests.
• Allowing a person without corporate authority to sign for the assignor or assignee.
• Leaving the patent number, title, effective date, or transferred rights ambiguous.
• Failing to check renewal status and remaining patent term.
• Submitting inconsistent names across the agreement, certificate, company records, and Power of Attorney.
• Assuming recordal is automatic after signing the private contract.

What does a realistic Nepal patent assignment look like?

Imagine a Kathmandu clean-cooking startup whose founder obtained a Nepal patent before incorporation. The startup signs a deed identifying the patent, receives the founder’s title warranties, obtains company approval, and asks a Nepal representative to submit the recordal request to the DoI.

The agreement may also require the founder to assist with renewals, enforcement, and any later correction. The company should retain the signed deed, patent certificate, corporate resolution, and DoI confirmation together. This is a realistic business solution, but it is not a substitute for checking the actual patent file.

If the startup instead wants the founder to retain ownership while the company commercialises the invention, a licence may be better. If an investor is taking security, a security document may raise different questions. Do not force every commercial arrangement into a patent assignment.

What alternatives and edge cases should you consider?

A patent assignment is only one way to organise control of an invention. A licence, corporate restructuring, inheritance, merger, security arrangement, or correction of the owner’s name may require different documents and DoI treatment. The correct route depends on whether ownership truly changes or only the recorded details change.

• Licence: permits use while ownership remains with the patent holder.
• Name change: corrects the owner’s recorded identity without necessarily transferring ownership.
• Merger or acquisition: requires evidence linking the former owner to the successor entity.
• Co-ownership: requires careful treatment of each owner’s interest and signing authority.
• Foreign assignment: needs local filing support and suitable foreign corporate evidence.
• Pending application: needs a specific DoI procedure check rather than an assumption that granted-patent rules apply.
• Expired or cancelled patent: cannot be treated as a live asset without first resolving its status.

The WIPO explanation of patent ownership and technology transfer can provide wider background. Nepal’s recordal, however, remains a national DoI matter.

How can IP Sewa help with a DoI patent assignment?

Our team can also assist with patent registration, renewal, and related IP work. The scope depends on your patent file, parties, and transaction documents.

Send the patent certificate, ownership details, proposed transaction, and any existing licence or financing documents through our contact page. We can help you identify gaps before signing and explain which current DoI documents are needed. For wider patent filing support, see our patent registration service.

In short: what should you do first?

Start by checking who owns the Nepal patent and whether it remains in force. Then prepare a precise assignment agreement, obtain proper authority and certification, file the recordal request with the DoI, and preserve proof of the updated ownership record. Do not rely on a private contract alone.

• Confirm the patent and chain of title.
• Choose assignment or licence based on the real transaction.
• Identify every party and transferred right.
• Prepare the current DoI supporting documents.
• File and follow up until the record is updated.
