Observers in Vietnam were recently captivated by a trademark application filed by a famous singer, Truong Trieu Truc Lan (also known as Nathan Lee), for the mark “CAO THAI SON” for “real estate services” in Class 36, “entertainment and stage performances” in Class 41 and “restaurant services” in Class 43. “Cao Thai Son” is the real name of another famous Vietnamese singer. The application astonished the community not only due to Nathan Lee’s attempt to register another person’s name, but also because Nathan Lee and Cao Thai Son have a longtime rivalry, and after buying copyrights to many of Cao Thai Son’s hit songs, Nathan Lee’s registration of his rival’s own name has obviously deepened the animosity between the two. If this mark is exclusively granted to Nathan Lee, Cao Thai Son’s fans are worried that their idol could no longer use his own name in his performing career due to risks of trademark infringement. Their concern is not groundless in the context that protection of trademarks in Vietnam mostly depends on registration. Rights to non-registered objects, even well-known marks, are still rather difficult to obtain and enforce. However, the right to an individual’s name is a moral right, which cannot be bought, sold, transferred between living people, or inherited. Article 26 of Vietnam’s Civil Code affirms that individuals “have the right to have a full name (including a middle name, if any) … determined by the person’s first and last name at birth,” and that they “establish and perform civil rights and obligations according to their surname and name.” Thus, Cao Thai Son, as an individual, has the right to use his name in civil transactions. He can also use his name in his performances, regardless of whether the trademark “CAO THAI SON” is granted to Nathan Lee,
