Platinum Technology Inc, based in Oakbrook, Illinois, and Platinum Software Corp, Irvine, California, are pumping out missives reminding folks that the companies are not one and the same. Platinum Technology has apparently taken hits on its share price when Platinum Software news has been mistakenly attributed to it. The headlines [including Platinum dumps Unix] have been killing us, says the company. Worried that customers would run, Platinum Technology’s UK office ran a series of advertisements in the London Times detailing the differences. Why not add Platinum Software to its acquisition roster? That’s another possibility, but we would rather partner with them than buy them, the company says. Neither side is considering suing to remove the other’s name. If letters to editors do not work, Platinum Technology will keep asking for retractions.
