After reportedly dropping its earlier lawsuits against LG (066570), Samsung (005930) on Tuesday filed a brand new suit against its South Korean rival over alleged slander committed in a refrigerator ad. For those who need a refresher, Samsung and LG had been locked in a patent battle over OLED and LCD display technology, although both were said to be working toward patent peace with a settlement. LG recently reaffirmed its suit against the company and demanded compensation, and even made threats against Samsung’s new Galaxy S 4 smartphone. Unlike earlier disagreement, however, the latest lawsuit does not involve patents.

According to the Korea Herald, Samsung claims that LG ran a series of advertisements that contained false information and have allegedly “tarnished its corporate image.” The controversy started when Samsung produced an advertisement that mocked the purported small size of LG’s refrigerators. The Korea Herald says that LG “released online advertisements condemning Samsung Electronics” in response that Samsung alleges “misconstrued facts” about the company.
