Exxon Unit Wins Damages From Lubrizol: A federal judge more than doubled damages against Cleveland-based Lubrizol Corp. to $129 million for infringing on a 1989 Exxon Chemical Co. patent for a motor oil additive. U.S. District Judge Norman Black entered the award for Exxon after reviewing a jury award of $48 million, made last November. A Lubrizol spokesman said the company was disappointed and would appeal the judge’s ruling. At issue was a copper component used in motor oil mixtures sold to oil companies. After the December, 1992, verdict, Lubrizol removed the copper component from its additive packages.
