Samsung Display has finally won a five-year patent fight against Gold Charm, a patent troll founded by Hon Hai of Taiwan, the parent company of Foxconn.

Samsung Display has finally won a five-year patent fight against Gold Charm, a patent troll founded by Foxconn's parent company, Hon Hai of Taiwan.

In early 2012, Hon Hai bought patents on liquid crystal display (LCD) technology from NEC in Japan for about 130 billion won, and established a patent litigation company named Gold Charm to attack competitors such as Samsung Display. Afterwards, Gold Charm filed lawsuits against Samsung Display’s customers to put pressure on Samsung Display. Samsung Display actively participated in the lawsuits to protect its customers, starting the five-year patent war.

Gold Charm filed a total of 12 patent infringement lawsuits against Samsung Display’s customers, half of which were invalidated by the Patent Trial and Appeal Board (PTAB) and the remaining six cases were ruled in favor of Samsung Display by the Delaware federal court. Gold Charm took the case to a U.S. appeals court, which recently confirmed Samsung Display 's victory.

"The patent troll will be able to appeal to the Supreme Court until the end of May, but this case is considered virtually over because the Supreme Court is highly unlikely to accept the appeal," said an official of the display industry.
