The only purpose or effect of the tying clause, so far as it could be effectively applied to patented articles, is either to prevent the use, by a lessee, of the product of a competitor of the lessor, where the lessor's patent, prima facie, embraces that product, and thus avoid judicial review of the patent, or else to compel its examination in every suit brought to set aside the tying clause, although the suit could usually result in no binding adjudication as to the validity of the patent, since infringement would not be in issue.

It is stipulated that appellant derives a 'substantial' profit from its card sales. The gross receipts from its machines during the past ten years have averaged $9,710,389 a year, and an average of $3,192,700, has been derived annually from the sale of its cards. These facts, and others, which we do not stop to enumerate, can leave no doubt that the effect of the condition in appellant's leases 'may be to substantially lessen competition,' and that it tends to create monopoly, and has in fact been an important and effective step in the creation of monopoly.

The agreed use of the 'tying clause' by appellant and its only competitors, and the agreement by each of them to restrict its competition in the sale of cards to the lessees of the others, have operated to prevent competition and to create a monopoly in the production and sale of tabulating cards suitable for appellant's machines, as the District Court found. The commerce in tabulating cards is substantial. Appellant makes and sells 3,000,000,000 cards annually, 81 per cent.
