Excedrin Makers Give Rival a Headache: The makers of Excedrin PM said they have obtained a federal court order against the makers of Tylenol PM for allegedly trying to confuse the public by using packaging similar to their product. The makers of Tylenol PM denied the allegation and plan to appeal the decision. Bristol-Meyers Squibb Co. filed a suit last May, contending that McNeil-PCC Inc. violated federal trademark laws. Judge Arthur D. Spatt of the U.S. District Court in Brooklyn issued a preliminary injunction prohibiting McNeill from “using, selling, offering for sale and distributing” Tylenol PM tablets and caplets in current packaging. McNeil-PPC Inc. is a unit of Johnson & Johnson Co., which is based in New Brunswick, N.J.
