Trademark Use in Vietnam: How to Correctly Understand and Effectively Rebut Non-Use Cancellation Attacks

[vc_row triangle_shape="no"][vc_column][vc_column_text] Download In Vietnam, owning a trademark registration is only half the battle - keeping it alive is where the real challenge begins.

What if your products haven’t yet entered the Vietnamese market? What if your app or website is used by Vietnamese consumers but your company is based abroad? Does that count as “use”? Vietnam’s IP Law draws a fine line between registered rights and active rights - and the distinction...

Posted by Dương Thúy

in Notable Articles, Trademark, Viet Nam

Download In practice, it is not uncommon for two entirely independent entities to file applications to protect an identical or similar sign for the same goods/services - sometimes even on the very same day. What may appear to be a mere coincidence, however, presents an intriguing legal question: when both applications satisfy the filing-date requirement equally, who has priority? Who will be the lawful owner of the mark? In a rare case, a client of KENFOX IP & Law Office - Eurotek Vietnam Lubricants Co., Ltd. (Công ty TNHH Dầu nhớt Eurotek Việt Nam) - filed an application for the mark “”...

Posted by Dương Thúy

in Notable Articles, Patent, Viet Nam

[vc_row triangle_shape="no"][vc_column][vc_column_text] Download Launching a product in Vietnam without an FTO check is like driving at night with the headlights off, possible, but risky and expensive. Vietnam recognizes utility solutions (utility models), a powerful doctrine of equivalents in infringement analysis, and broad “Bolar”-style regulatory approval exceptions. Knowing which of these helps you, and which hurts you, often decides whether your launch flies or stalls. For foreign enterprises considering entry into the Vietnamese market, conducting a Freedom-to-Operate (FTO) search is not a simple administrative box to check; it is a critical, proactive tool for risk mitigation and strategic business planning.

Posted by Dương Thúy

in Notable Articles, Trademark, Vietnam

[vc_row triangle_shape="no"][vc_column][vc_column_text] Download The act of “repeat infringement” has long been considered a basis for imposing harsher sanctions, including punitive damages. China’s legal system expressly allows this approach, but proving repeat infringement in practice requires a clear and convincing chain of evidence. A recent ruling by the People’s Court of Yuexiu District, Guangzhou, in a dispute involving Cartier, illustrates how Chinese courts evaluate evidence to establish repeat infringement and justify punitive damages. The case highlights the practical methods right holders can employ to strengthen their claims, while also exposing the current legal gap in Vietnam, where punitive damages remain unavailable. Background Cartier, a globally...

Trademark Assignment in Vietnam: Why It’s Refused and How to Overcome It?

Posted by Dương Thúy

in Notable Articles, Trademark, Viet Nam

Trademark assignment in Vietnam is subject to strict statutory requirements and substantive examination by the Intellectual Property Office of Vietnam (“IPVN”).

KENFOX IP & Law Office, with over 15 years of practical experience and expertise in IP protection in Vietnam, provides in-depth analysis of the risks associated with trademark assignment, along with strategic...
