Can a co-owner of a trademark be transferred arbitrarily?

In today's business activities, many trademarks are created by many individuals or organizations that jointly invest, develop and register for protection. This is a fairly common situation for family businesses, startups, joint ventures, or business cooperation models that use the same brand. In fact, many people think that as long as they are one of the co-owners, they have the right to sell themselves, transfer themselves or sign a contract to exploit the trademark without the consent of the other party.

1. How is co-ownership of a trademark regulated by law?

1.1. Trademarks can be owned by multiple entities

According to the Law on Intellectual Property 2005 amended and supplemented in 2022, the ownership of a trademark may belong to one or more organizations and individuals under the same name to register for protection. In this case, the subjects are considered as co-owners of the trademark and have the same rights and obligations related to that intellectual property property. This is a mechanism that often appears in models of investment cooperation, brand co-founding or joint business exploitation.

1.2. Why are trademark co-ownership disputes increasingly common?

When a trademark is not of great value, many parties often only agree orally or under a common name without building a clear ownership management mechanism. However, when the brand thrives or there is a need for transfer, franchising, and raising investment capital, the right to control the trademark becomes a very sensitive issue. In many cases, a party arbitrarily signs an exploitation or transfer contract, causing disputes to arise for a long time and seriously affect business activities.

2. Can a co-owner transfer a trademark at will?

2.1. The right to dispose of co-owned property is restricted

2.1.1. Not a co-owner has the right to sell the entire trademark by himself or herself

According to the principles of civil law and intellectual property law, jointly owned property must be disposed of according to the agreement of the co-owners, unless otherwise agreed. This means that a co-owner of a trademark does not automatically have the right to transfer the entire trademark to a third party without the consent of the other owners. If the transaction is made on its own, the contract may have a dispute over its validity or liability to compensate for damages.

2.1.2. Why is this regulation especially important for trademarks?

Unlike many common assets, trademarks are directly associated with business activities, commercial reputation and exploitation rights in the market. The arbitrary transfer of one party can directly affect the business interests, brand control and development strategy of the remaining co-owners.

2.2. Can I transfer my ownership?

2.2.1. Depends on the nature of ownership and internal agreements

In fact, many people confuse the transfer of the entire trademark with the transfer of their interest in co-ownership. However, even if only the ownership related to you is transferred, the transaction can still directly affect the rights and mechanisms of exploiting the trademarks of other co-owners. Therefore, the transfer often requires careful consideration of internal charters, co-ownership agreements and the potential impact on commercial exploitation.

2.2.2. Risks of bringing outsiders into co-ownership relationships

If a party transfers rights to a third party without appropriate control mechanisms, the trademark management structure may be completely changed. This is especially dangerous in family businesses, startups, or brands that are being exploited centrally by a team of founders.

3. Legal risks if you arbitrarily transfer a co-owned trademark

3.1. Risk of the contract being disputed or invalidated

If the transfer transaction is carried out without authority or violates the rights of other co-owners, the transferee may not achieve the stable exploitation rights as expected. When the transaction causes damage to other co-owners or affects the joint business, the transferor may incur liability for compensation. In many cases, disputes do not only stop at intellectual property rights but also entail huge contractual disputes and financial liabilities.

3.2. Impact on brand exploitation activities

When new entities join the co-ownership relationship, brand management and control of mining activities often become much more complicated. If there is no clear voting mechanism or division of rights, internal disputes are very easy to arise. Disputes related to ownership often directly affect the reputation and commercial exploitation of a brand.

4. What should be done to limit trademark co-ownership disputes?

4.1. Build a clear co-ownership agreement from the start

The parties should have a document clearly stipulating the right to use, licensing, transfer, and the handling mechanism when a party wants to withdraw from the co-ownership relationship. In addition to the issue of ownership, the parties should also agree in advance on the dispute resolution mechanism and voting principles for important decisions related to trademarks.

4.2. Carefully check legal documents before receiving the transfer

For the transferee, reviewing the status of co-ownership and the right to dispose of the contracting party is a particularly important step. Many transactions seem legal but in fact have serious disputes because the transferor does not have full authority over the trademark.

5. The role of lawyers in trademark co-ownership transactions

Disputes related to trademark co-ownership are often not only a matter of registration procedures but also directly related to commercial exploitation rights and intellectual property control strategies. Lawyers have the role of reviewing ownership, evaluating the validity of transactions, building co-ownership mechanisms and controlling legal risks in the process of transferring or exploiting brands. In many cases, even a sketchy clause in a co-ownership agreement can lead to a dispute that lasts for years.

Conclusion

Co-ownership of a trademark does not mean that each owner has the right to voluntarily transfer all intellectual property assets to a third party. In the context that intellectual property is increasingly valuable and plays an important role in business activities, building a clear co-ownership mechanism and having a lawyer to control transactions early is an important solution to limit disputes and protect the long-term interests of enterprises.
