The Vietnamese government has taken steps to make the country an attractive place to do business by signing several major international treaties in recent years. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership came into effect in 2019, followed by the Hague Agreement, the EU-Vietnam Free Trade Agreement and the Regional Comprehensive Economic Partnership in 2020. A draft amendment of the Law on Intellectual Property was published late last year with the aim of complying with the requirements of these treaties and preparing Vietnam for accession to others in future. For manufacturers, the country is becoming an increasingly popular alternative to China and having a solid patent protection strategy is becoming a priority.

Nguyen spent seven years as an examiner at the National Office of Intellectual Property of Vietnam (NOIP) and has been a registered patent and trademark attorney for close to 30 years. Clients benefit from a regional network of IP experts as the side works closely with associates in Vietnam, Myanmar, Laos and Cambodia.

Baker McKenzie

Valued for its “high service quality and professionalism”, Baker McKenzie’s Vietnam team offers the full range of patent services from filing to enforcement. The practice boasts an impressive track record and has continued to expand year after year. Manh Hung Tran and Viet Hung Le play an active role in solidifying Vietnam’s status as an increasingly important player on the international IP stage; they recently acquired protection for several Vietnamese patent owners in the United States. A new addition to WTR 1000, Le was involved in drafting Vietnam’s first IP laws and was instrumental in negotiating the IP aspects of the country’s accession to the World Trade Organisation. Another thing that sets the firm apart is the duo’s “great technical understanding”. As well as giving advice, they support companies in reaching their goals and are “very efficient in working with other offices in their network, which is a plus”.

D&N International

A familiar name in local IP circles, D&N International has assisted clients in acquiring and protecting IP rights since 1992. The outfit sets itself apart through its international outlook and technical expertise. Specialising in chemical and biochemical engineering, Thuy Dang founded the firm after seven years of working at the NOIP.

Pham & Associates

The oldest IP-focused firm in Vietnam, Pham & Associates once again defends its spot in the gold tier this year. Peers consistently speak highly of the hardworking team led by Vu Khanh Toan Pham. The founder and managing partner is a former NOIP official. Under his leadership the practice has grown to become one of the country’s top filers.


With a long history of operating in the ASEAN region, Rouse is a popular choice with prominent multinationals in need of patent services. “They have the skill and experience required” to tackle intricate cases and “achieve great results, going through a lot of effort for their clients”. The multilingual team produces quality technical translations – something that is sure to appeal to key patent owners. Overseeing the practice is Yen Vu, whose international exposure and broad IP knowledge ensure that she is perfectly equipped to develop sophisticated IP protection strategies for global corporations. Chemical engineer Dung Vu’s strengths lie in the chemical and pharmaceutical fields, although she can be relied on to prosecute patents in any industry with ease. She is also frequently involved in handling infringement matters.

Tilleke & Gibbins

Now the country’s second largest filer, Tilleke & Gibbins is putting pressure on its competitors. The ambitious firm is on a path of expansion; in August 2020 the Hanoi-based faction moved into a larger office to accommodate 95 largely IP-focused members. Moreover, the outfit has been growing its specialist team dedicated to electronics – an area drawing increasing interest in Vietnam. Tilleke’s IP enforcement practice, headed by Loc Xuan Le, enjoys an outstanding reputation, with seven of the 10 largest global pharmaceutical companies enlisting its services. Managing director Thomas Treutler is another experienced enforcer who has secured landmark victories for numerous clients in the life sciences and technology sectors. Highly regarded in their respective fields, Thanh Phuong Vu heads the biotechnology and chemical division, while colleague Hung Tuan Nguyen oversees the mechanical and electronics division.


TRUNG THUC JSC’s patent attorneys are experienced IP practitioners capable of tackling technical matters in any field. Managing partner Hai Yen Thieu specialises in pharmaceutical, biotechnology and chemical patents, while Viet Thang Nguyen’s practice centres around patent and industrial design cases in the mechanical, telecoms and new material science fields. Nguyen represents world-renowned companies such as Panasonic and AstraZeneca.


Vietnam’s first IP agency, VCCI-IP, was established in 1984 following the opening of the National Office of Invention, now known as the NOIP. An affiliate of the Vietnam Chamber of Commerce and Industry, it has become well known for handling high volumes of patent filings.

Vision & Associates

Prolific patent filer Vision & Associates combines deep local knowledge with an excellent grasp of international standards to offer IP services for large global companies. Pham Nghiem Xuan Bac’s practice extends from NOIP proceedings and advisory work to corporate law. IP practice director Nguyet Dzung Nguyen is another prominent practitioner with numerous successes under his belt for some of the world’s most recognisable patent owners.

Winco Co Ltd

One of the youngest firms in the top ranks of Vietnamese patent practice, Winco was established in 2002. Since then, the team has worked hard to grow the outfit into one of the country’s most respected patent practices. Clients turn to Winco for patent advice across the ASEAN region. Phung Chi Cong is head of the patent department and a name to remember.
