Areas of expertise: Patents, Trademarks, Intellectual Property Litigation, and Intellectual Property Rights Enforcement.
With over 15 years of experience in the intellectual property (IP) field in Vietnam and the ASEAN region, Ms. Hoang Thi Tuyet Hong is one of KENFOX’s core personnel in the areas of patents, trademarks, litigation, and IP enforcement. Starting as a patent specialist in 2011, she has directly handled over 1,000 patent applications and hundreds of trademark and copyright cases in Vietnam, Laos, Cambodia, and Myanmar – building a rare practical foundation encompassing registration, strategic consulting, dispute resolution, and enforcement.
Ms. Hong’s distinguishing feature is her ability to connect legal, business, and enforcement aspects. She doesn’t stop at simply “obtaining a patent,” but designs IP strategies that are integrated with business models, supply chains, product roadmaps, and market expansion plans. From her perspective, each patent, each trademark, each copyright must be “placed in its proper place” within the business ecosystem: it is an asset that can be protected, exploited, transferred, create a negotiating advantage, and generate profit for the business, not just a formal registration right.
Ms. Hoang Thi Tuyet Hong is currently the Head of the Trademark & Copyright. At KENFOX, Ms. Hong is a highly experienced IP expert, having developed her career starting as a patent specialist before expanding into trademark and copyright consulting and comprehensive protection strategy planning for businesses. She graduated with a degree in English from Hanoi University and holds a Bachelor of Laws degree (domestic and international, with a good grade) from Hanoi Law University, one of the leading and most prestigious law schools in Vietnam. The combination of her foreign language and legal background makes Ms. Hong particularly adept at working with international clients, explaining complex legal issues in clear yet precise and professional language.
Before specializing in the field of IP, she worked as a legal counsel for the Deputy Head of the Legal Assistance Department – Hanoi Department of Justice for two years, participating in legal services and judicial translation. This period helped her gain a thorough understanding of the “language” and operating mechanisms of the legal system, how state agencies evaluate files and evidence, as well as the standards for validity and persuasiveness of legal documents – factors that later became a great advantage when she entered the field of IP.
Prior to joining KENFOX, Ms. Hoang Thi Tuyet Hong spent nearly 10 years working at one of Vietnam’s top four IP law firms, where she oversaw and managed the IP filing system, directly handling over 1,000 patent applications for domestic and international clients, and expanding into trademark, copyright, and related areas. This experience gave her a deep understanding not only of the theoretical process of handling patents and trademarks, but also of the practical “bottlenecks” commonly encountered when working with IP offices and implementing multinational protection strategies.
At KENFOX, Ms. Hoang Thi Tuyet Hong is a strategic focal point for patents and trademarks in Vietnam, Laos, Cambodia, Myanmar, and other ASEAN countries. She has comprehensive experience in filing, pursuing, renewing, transferring, recording changes, objecting, requesting invalidation, evaluating, and enforcing IP rights. Her expertise spans:
As a multidisciplinary IP consultant with a Vietnamese law degree and over a decade and a half of in-depth experience, Ms. Hoang Thi Tuyet Hong is highly regarded for her ability to develop appropriate and effective IP strategies for various types of businesses – from startups building their technology platforms, small and medium-sized enterprises in the expansion phase, to multinational corporations requiring cross-border IP mapping in ASEAN. She accompanies businesses throughout the entire IP asset lifecycle, from the idea stage – registration – exploitation – defense – portfolio restructuring, helping clients proactively mitigate risks, optimize costs, and transform IP into a true pillar of their competitive strategy.
In the case of trademark infringement of LACTOMASON by the South Korean company LACTOMASON CO., LTD. A Vietnamese company, “Lacto Mason Vietnam Co., Ltd.”, brazenly used the “LACTOMASON” trademark, which was almost identical to the original trademark, on a series of women’s health care products. They incorporated it directly into their company name and exploited it consistently across their website, social media, advertising materials, and signage – a deliberate, sophisticated, and well-organized infringement scheme. In this case, Ms. Hong affirmed her role as the “execution architect”: designing the entire process from investigation and evidence gathering to expert assessment and on-site raid, coordinating closely with market management forces and expert assessment agencies. Her highlight was her ability to transform a complex legal case into a sharp action plan, effectively controlling risks and producing concrete results: nearly 8,500 units of infringing products were seized and destroyed, the infringing party was fined over 700 million VND, and the value of the infringing goods was nearly… 1.5 billion VND. This helps protect the legitimate rights of the owner and sends a strong deterrent message to those who intend to “take shortcuts” by exploiting international brands.
In the “FOELLIE” trademark dispute, the context was particularly complex: the Vietnamese party (Luu Ngoc Anh/La Pharma) exploited the “first come, first served” principle to obtain the trademark certificate, while simultaneously implementing a series of retaliatory actions – sending threatening warning letters to the official distributor, demanding Shopee/Lazada/TikTok remove the sales account, and filing complaints with e-commerce regulatory authorities – all while they themselves had been identified as having copied the copyrighted “Foellie” logo. Initially, Vietnamese authorities and platforms were confused and handled the situation rather mechanically, failing to clearly distinguish between trademarks and copyrights, paralyzing Laorganic’s official distribution channel and causing a significant drop in sales.
In the context of such “conflicts of rights” and procedural abuses, Ms. Hong played a prominent role as a strategic architect: she designed a roadmap to prove the registration was fraudulent and abusive (copyright assessment at ECCR, building a dossier requesting the cancellation of the trademark certificate based on Articles 74.2(g), 87.2, and 96 of the IP Law), while persistently appealing to digital platforms to force them to independently distinguish between trademarks and copyrights, and restore Laorganic’s account and genuine content. As a result, the IP Office issued a decision to cancel certificate 525787 “FOELLIE,” TikTok Vietnam and the platforms adjusted their handling procedures, thereby not only “returning the name” to the true owner but also setting an important standard for preventing abuse of IP procedures in Vietnam.
Ms. Hong regularly participates in and presents at professional seminars on IP in Vietnam and the Asian region, with typical topics such as:
