  • Engelhard Arzneimittel GmbH & Co. KG. v. Vinh An Thang Long Investment JSC

Represented Engelhard Arzneimittel GmbH & Co. KG. (“Engelhard Arzneimittel”), a 140-year-old Germany-based pharmaceutical company with a strong commercial presence in Vietnam through the sale of cough medicine bearing the mark “ ” (PROSPAN). Engelhard Arzneimittel’s Vietnamese distributor, Sohaco Pharmaceutical Group, provided QUAN with initial information that a Vietnamese entity named “Vinh An Thang Long Investment JSC” (“Vinh An Thang Long”) manufactured and marketed cough dietary supplement products bearing the mark “ ” contained in packages of which outer representation carrying a high degree of the Prospan cough dietary supplement package. The case was submitted to Vietnam Competition Administration Department (“VCAD”), which is now known as “Vietnam Competition and Consumer Authority” (“VCCA”) for settlement under unfair competition proceedings. VCAD sought expert opinions/expert witness from the “National Office of Intellectual Property of Vietnam” (“NOIP”), which is currently known as the Intellectual Property Office of Vietnam (“IP Vietnam”). NOIP, after reviewing the case, gave its written opinion that the use of packages with an outer layout similar to that of Engelhard Arzneimittel constituted unfair competition. The working session was then held with the participation of the director of Vinh An Thang Long as the infringer, QUAN, as the IP attorney of Engelhard Arzneimittel, and VCAD officials. Vinh An Thang Long was forced to terminate its unfair competition and a huge fine was imposed on the infringer.


  • DIHON Pharmaceutical Group Co., Ltd. v. Asem Vina JSC

Represented DIHON Pharmaceutical Group Co., Ltd. (“DIHON”), a China-based reputable pharmaceutical company with a significant commercial presence in Vietnam through the sale of medicated shampoo branded “ ” (Haicneal). DIHON’s Vietnamese distributor, Dong A Pharmaceutical JSC, informed QUAN that a company in Hai Duong Province, Vietnam named “Asem Vina JSC” manufactured and marketed cosmetic shampoo under the mark “ ” (HAINOZAL), but the shampoo packaging’s outer appearance is strikingly similar to that of DIHON. Under the leadership of QUAN, an in-depth investigation revealed that a large quantity of HAINOZAL cosmetic shampoo was being manufactured at the Asem Vina JSC factory. The case was submitted to the Inspectorate of the Ministry of Science & Technology (“IMOST”). After securing the NOIP’s expert opinions/expert witness in favour of DIHON, a raid was conducted against Asem Vina JSC. Thousands of infringing products were seized and destroyed before the witness of DIHON and IMOST.


  • Lacoste v. two counterfeit wholesalers in Hanoi Old Quarter

Represented Lacoste in coordinating raids against 2 clothing stores in Hanoi Old Quarter. The pre-raid investigations leaded by QUAN uncovered that these 2 stores served as major wholesalers of Lacoste counterfeit clothes in Hanoi, Vietnam. The case was submitted to the Inspectorate of the Ministry of Science & Technology of Vietnam for handling under administrative proceedings. As a result, a large quantity of 1073 garments bearing the mark “LACOSTE” and “ ” were seized and destroyed. A fine of VND 183,360,000 was imposed on the two counterfeit wholesalers.


  • Reversing expert opinion/witness issued by Vietnam Intellectual Property Research Institute (“VIPRI”)

Represented a California-based nutraceutical ingredient manufacturer of nutraceutical ingredients in obtaining VIPRI’s assessment conclusion (expert opinion/witness) in a trademark infringement case. After reviewing the assessment request, VIPRI determined that there was insufficient evidence to conclude that the suspected trademark used by a company in Vietnam infringed on the manufacturer of nutraceutical ingredients. QUAN filed a counter-opinion to VIPRI’s assessment conclusion after concluding that it is unsatisfactory. After several working sessions, VIPRI changed its expert opinion and concluded that the assessed trademark used in Vietnam by a third party was an infringement of the registered trademark of the California-based manufacturer of nutraceutical ingredients. This victory is quite significant taking into account that it is not a common pratice to challenge the VIPRI opinion, and it is very difficult to reverse the VIPRI opinion once it is issued.


  • Pursuing an evasive manufacturer of dishwashing liquid who was infringing on a multinational Dutch company’s industrial design rights

The alledgedly infringing products were found in some e-commerse websites in the Internet. The issues are that (i) the seller only left a telephone number for customers to negotiate prices on the products and (ii) information on the manufacturer on the plastic bottles of dishwashing liquid is very vague. This trick obviously aims at preventing the IPR holders and Vietnamese enforcement from keeping track of the infringing manufacturer/supplier, the warehouses, the loading points, counterfeit networks, etc. After constant efforts and with highly investigative skills in interact with the seller, placing trap orders and monitoring, QUAN eventually succeeded in detecting the infringer’s premises which was secretly located within a big factory of the infringer. To support an infringement claim, a request for VIPRI’s Assessment Conclusion was submitted. VIPRI gave its opinion that the outward appearance of the bottle of dishwashing liquid manufactured by the Vietnamese entity infringed the Dutch company’s industrial design rights protected in Vietnam. The case was submitted to IMOST, which then conducted a raid in collaboration with local police against the Vietnamese infringer. Over 5,000 bottles bearing the infringing industrial design were seized and destroyed. The case was made public on the IMOST website as an example of a typical case involving industrial design rights infringement in Vietnam.


  • Dealing with company name and domain name infringing trademark rights

Represented a US company in a trademark-based domain name and company name dispute. In detail, the US company, a retail pharmacy company, has registered trademarks in Vietnam for pharmaceutical products in Class 05 and medical apparatus in Class 10. The US company detected that a Vietnamese entity (“Entity A”) established a company with a name highly similar to their trademark. In addition, Entity A has also registered a domain name and activated a website with a similar name. The challenges of the case lie in the fact that there had existed another company (“Entity B“) incorporated in Vietnam with a name almost identical to that of Entity A. Entity B’s company name served as their trade name, which had been established before the US company’s trademarks were registered in Vietnam. This could result in an argument that similar trade names (or company names) of Entity A and Entity B have co-existed in Vietnam without causing actual confusion to consumers – one of the key elements for establishing trademark infringement in Vietnam. Thus, Entity A may invoke the prior existence of Entity B’s trade name to justify its use of a similar company name. Another weakness of the US company is that Entity A’s trademark was intended for goods in Class 05, but the US company’s trademark registration in Class 05 occurred after the adverse party’s company was established, making it hard to take enforcement action in Vietnam based on the US company’s Class-5 trademark registration.


QUAN is directly involved in this complicated trademark case. After reviews and analysis, a petition was submitted to the IMOST, who then conducted a raid against the Vietnamese entity. The legal representative of the Vietnamese company admitted his infringement during the IMOST working session and was forced to change the company’s name and return the domain name to the US company for registration.


  • Customs seizures

Represented a Vietnamese door lock giant in coordinating with the Anti-smuggling and Investigation Department (“ASID“) – an agency under the Vietnam General Department of Customs (VGDC) to suspend customs clearance for a Vietnamese company while importing various containers of multiple goods into Vietnam. A container of counterfeit door locks was discovered during a physical examination conducted by ASID in front of the witness, QUAN, who serves as the IP attorney for the Vietnamese trademark owner. The entire shipment of forgeries was seized. Due to the high volume of counterfeits, the case was being investigated for criminality.
