What Is The Tying Agreement
c) Important exchanges with the related product For a commitment agreement which is in itself illegal, the intergovernmental trade29 of the linked product had to be affected in a "significant" way. The Supreme Court stated that the relevant question was "whether a total amount of transactions substantial enough relative to the volume of the dollar to be not solely de minimis is closed to competitors." 30 In the United States against Lews, for example, the Supreme Court has held that as little as $60,000 is not negligible.31 Starting with the question "whether there is a possibility that the economic impact of the agreement is that . . . The petitioners closed competition on the merits of a separate product market from the binder market"42 The Supreme Court rejected a functional relationship approach to determining whether one or two products were involved. Instead, the Court focused on the nature of the application for the two products: 2. OTHER AFFAIRES In addition, the Commission has looked at a number of coupling cases in which the company under investigation has renounced the alleged engaging behaviour and has not been the subject of a formal decision. The case of IBM,93, which raised the issue of product integration (or the technological link), is of particular interest. 4. OBJECTIVE JUSTIFICATION In principle, dominant companies accused of abusive links can strengthen the defence of objective justifications. However, in practice, there is not yet an example of a successful defence. For example, Hilti argued that the attachment of the sale of her nail guns to the sale of her nails had enhanced the safety and reliability of the entire fastening system. The Commission rejected Hilti`s justification for a number of reasons that focused mainly on security aspects: for at least three decades, the Supreme Court defined the necessary "economic power" to encompass almost any deviation from perfect competition, until the possession of copyright, or even the existence of a tie, , has given rise to a presumption of economic power.
 In the meantime, the Supreme Court decided that an applicant must determine the market power necessary for other cartel violations in order to demonstrate sufficient "economic power" to establish one.  More recently, the Court struck down any presumption of market power solely on the basis of patenting or copyright of the binder product.  The Link Act is changing. Although in the past the Supreme Court has treated some linkage points as illegal in itself, the preliminary bodies have begun to apply the more flexible "rule of reason" to assess the competitive impact of tied sales. The cases deal with specific framework conditions, but the general rule is that binding the products raises questions of cartel law when they restrict competition without offering benefits to consumers. With regard to the need to obstruct competition, the position is a reflection of the testing of individual products. Jefferson Parish raised the threshold for the mere de minimis standard of de minimis from a "significant volume of trade"113, according to the rule of the beginning of per sound, to "significant potential impact on competition." 114 Community competition law is, in turn, much closer to the first rule of per sound than Jefferson Parish. Under EU law, it appears that the reduction in consumer choice is inherently abusive, indicating that there is no need for silos (de minimis or otherwise).
