EXXON WINS PATENT CASE INJUNCTION AGAINST LUBRIZOL

 HOUSTON, Jan. 8 /PRNewswire/ -- Exxon Chemical Company today released the following:
 The Federal District Court for the Southern District of Texas at Houston yesterday issued a permanent injunction preventing Lubrizol Corporation (NYSE: LZ) from continued manufacture and sale of motor oil products infringing a U.S. patent granted to Exxon in 1989.
 This court action follows the verdict delivered by a jury on Dec. 23, 1992, finding that Lubrizol had infringed the Exxon patent on copper-containing formulations for use in motor oils. The court also found that Lubrizol's infringement was willful and that Lubrizol acted in bad faith. In addition, the court confirmed the validity and enforceability of the patent.
 "We are pleased both with the jury's verdict and with the court's decision on Exxon's motion to grant a permanent injunction," Ray Nesbitt, president of Exxon Chemical Company, said.
 "These actions affirm the strength and value of Exxon Chemical's PARAMINS additives technology for motor oils. Moreover, they provide strong protection for patent rights granted to Exxon for a significant invention involving use of copper-containing formulations for motor oils. In view of the permanent injunction, it is Exxon's Chemical's intent to work to minimize disruption in the marketplace," Nesbitt added.
