The document discusses a dispute over the trademark "HWASUNG" between two Vietnamese companies, Thien Phu Company and SH-VINA Company. Thien Phu registered the trademark in 2005 but it was rejected by the Korean company Hwasung, who had previously used the trademark in Vietnam through distributors. In 2007, the intellectual property office canceled Thien Phu's registration, and in 2013 finally registered "SH-HWASUNG" to SH-VINA, recognizing them as the rightful owner.
