Byron White, Hanover Shoe, Inc. v. United Shoe Machinery Corp…
“ In looking at United's leasing system from the viewpoint of potential and actual competition, it must be confessed at the outset, that any system of selling or leasing one company's machines will, of course, impede to some extent the distribution of another company's machines. If a shoe manufacturer has already acquired one company's machinery either by outright purchase, by conditional purchase, or on lease on any terms whatsoever, the existence of that machine in the factory is a possible impediment to the marketing of a competitive machine. ”
