Song Hye-kyo
Production company NEW said that there have been hundreds of violations of their publicity rights by businesses, in an attempt to take advantage of the drama's success. The announcement came about when lead actress Song Hye-kyo sued jewelry firm J.Estina for using her pictures for promotion though the contract ended in January. J.Estina said in a press release that it abided by the contract with production staff of "Descendants of the Sun", which allowed it to use stills from the episodes as one of the main sponsors of the series. However, NEW refuted the claims, saying that the jewelry firm's arguments lacked legal grounds. Song Hye-kyo eventually won the legal battle and donated the damages received to charity.
