antitrust laws. During the pendency of that suit, Zenith Radio Corporation encountered increasing financial difficulty as their market share progressively went to Japanese companies. Concerned about losing market share to Japanese companies, Zenith filed suit in federal court in Philadelphia in 1974 against the major Japanese television and electronic manufacturers charging violation of the United States Antitrust Laws and the Anti-Dumping Act of 1916. Zenith joined two other U.S. companies Sears, Roebuck and Co. and Motorola, Inc. as co-plaintiffs. The NUE suit was transferred to the Eastern District of Pennsylvania and the two suits were consolidated for pretrial proceedings and trial. The suit, styled In re Japanese Electric Products Antitrust Litigation, sought $900 million in damages. By the end of 1983, Zenith had spent millions of dollars in connection with the litigation. In 1981, the trial court entered summary judgment on the antitrust and antidumping claims and dismissed the lawsuits. Plaintiffs appealed and the appellate court affirmed the summary judgment for Sears, Roebuck and Co., Motorola, Inc. and Sony. The case was appealed, and in March 1986 the Supreme Court of the United States ruled in favor of the defendants on Zenith’s antitrust claims. Zenith's hopes to salvage a victory on the claims that the defendants violated the Antidumping Act of 1916 ended in April 1987 when the Supreme Court refused to hear an appeal from the U.S. District Court of Appeals in Philadelphia which upheld the ruling of the trial court in favor of the Japanese. In 1979, Zenith entered the computer market with the purchase of Heath Company from Schlumberger for $64.5 million, and formed Zenith Data Systems (ZDS). The company changed its name to Zenith Electronics Corporation in 1984, to reflect its interests in computers and CATV, and since it had left the radio business two years earlier. By the late 1980s ZDS's profits sustained Zenith while its television business had lost money for years. To raise money for HDTV research efforts and reduce debt, Zenith sold ZDS to Groupe Bull in October 1989 for $635 million. By 1990, Zenith was in trouble and looking more attractive to a hostile takeover. To avoid this, Zenith sold 5% of itself to the Korean company GoldStar (now LG Electronics) as part of a technology-sharing agreement. With their analog line aging (the last major update to the line had been the System³ chassis in 1978), and the adoption of HDTV
