From Online Camouflage to Physical Crackdown: KENFOX’s Legal Strategy in the LACTOMASON Case

Posted by Quyen Nguyen

in Notable Articles, Trademark, Viet Nam

[vc_row triangle_shape="no"][vc_column][vc_column_text]Download 1. Snapshot of the Case In July-August 2025, KENFOX IP & Law Office executed a coordinated anti-counterfeiting operation in Hanoi on behalf of a leading South Korean pharmaceutical company, holder of the registered “LACTOMASON” trademark in Vietnam. The infringer was not a “street-level counterfeiter”, but a sophisticated entity constructed to project lawful legitimacy. Operating under the guise of “Lacto Mason Vietnam Co., Ltd.”, the infringer built a complete façade of brand authenticity by copying nearly the entire identity ecosystem of our client - including product packaging, labeling, corporate name, website, social-media presence, and promotional collateral - and then deploying a digital-only...

“L@TTITUDE” vs. “LATTITUDE”: How KENFOX Reversed a Refusal & Secured Protection in Vietnam?

Posted by KENFOX IP

in Notable Articles, Trademark

For many international brand owners, receiving a provisional refusal from the Intellectual Property Office of Vietnam (IP Vietnam) can feel like a dead end. Vietnam is one of ASEAN’s fastest-growing markets – but also one of its most rigorous trademark examination systems, where non-traditional marks face heightened examination, prior cited marks may block registration even with market differences, examiner discretion remains conservative compared to other Madrid members, consent letters are not automatically accepted, stylized, digital-era brand identities (e.g., symbols such as “@”) are often misunderstood under traditional distinctiveness rules A refusal in Vietnam is not merely an administrative hurdle – it...

Shutting Down Lookalike Packaging Through Unfair Competition Law – PROSPAN vs. PROSTIBAME

Posted by Vu Thu Uyen

in IPR enforecement, Notable Articles, Trademark, Vietnam

KENFOX IP & Law Office acted for Engelhard Arzneimittel GmbH & Co. KG. (Germany), owner of the “PROSPAN” cough remedy brand ( ), and its exclusive Vietnamese distributor, SOHACO, after a Vietnamese company (VINH AN THANG LONG Investment JSC) began marketing a PROSTIBAME cough “dietary supplement” in packaging deliberately modeled on PROSPAN’s presentation. The infringer avoided direct trademark conflict by using a different word mark (“PROSTIBAME”) (), and PROSPAN’s outer packaging had not been separately registered as a “trademark” or an “industrial design” in Vietnam - making a traditional infringement claim difficult. KENFOX responded by treating the dispute as an...

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

Posted by Dương Thúy

in Notable Articles, Trademark, Vietnam

In Vietnam, owning a trademark registration is only half the battle - keeping it alive is where the real challenge begins. Many foreign businesses secure broad protection for their brands across a wide range of goods and services, only to discover years later that their registrations are vulnerable to non-use cancellation. 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 can...

Identical Filing Dates, Identical Marks: Vietnam’s Resolution Mechanism and How Businesses Should Respond?

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 “”...
