With respect to the commissioning of Office, parallel proceedings brought against Microsoft by attorneys general contained an action for damages in the market for desktop productivity applications.  The Attorneys General waived this request when they filed an amended complaint. The claim was revived by Novell, where they claimed that computer manufacturers (“OEMs”) would be charged less for their massive Windows purchases if they agreed to bundle Office with any PC sold than if they left computer buyers the choice of whether or not to buy Office with their machines – making their computer prices less competitive in the market. Novell`s dispute has been settled.  Non-compliance agreements are not necessarily illegal. Anti-cartel concerns are raised by the fact that they are related to the extent that they are used to maintain or strengthen the seller`s existing market power or to impede competition in the market for the tied product. Certain types of plants, including contractual ones, have been considered anti-competitive practices in the past. The basic idea is that consumers are harmed by being forced to buy an unwanted good (the tied good) to buy a good they really want (the tied good), and therefore prefer to be sold separately. The merged company may have a considerable market share, which allows it to impose consumer engagement despite competitive forces in the market. Engagement may also harm other companies in the related good market or sell only individual components.
Collage can be divided into two different practices: one horizontal and the other vertical: membership (informal product link) is the practice of selling a product or service as a mandatory complement to the purchase of another product or service. From a legal point of view, a tied sale makes the sale of one thing (the tied goods) to the de facto customer (or de jure customer) subject to the purchase of a second separate product (the related case). Liability is often illegal when products are not naturally related. It is related, but different from freebie marketing, the usual (and legal) method of giving away an item (or selling with a substantial discount) to ensure a continuous flow of sales of another related item. The binder is the “practice of a supplier of a product, the binding product, where a buyer must also purchase a second product, the tied product”.  The union of a product can take different forms, that of the contractual union, if a contract obliges the buyer to buy the two products together, the refusal of delivery until the buyer accepts the purchase of the two products, the termination or withholding of a guarantee if the dominant seller does not offer the benefit of the guarantee until the seller accepts: purchase this product from this part. A technical link exists when the products of the dominant party are physically integrated and it is impossible to buy one product without the other and when two products are sold in the same packaging at a price. Such practices are prohibited by Article 101(1)(e) and Article 102(2)(d) and may constitute a breach of the law if other conditions are met. It should be noted, however, that the Court is prepared to find an infringement going beyond the infringements referred to in Article 102(2)(d) (see Tetra Pak v Commission).  Linkage is defined in Northern Pacific Railway Co.
v. United States (1958) as “an agreement by a party to sell a product, but only on the condition that the buyer purchases another (or related) product or at least agrees that it does not purchase that product from another supplier.” An agreement in which the seller enters into the sale of a product (the “binding” product) with the buyer`s agreement for the purchase of a separate product (the “bound” product) by the seller. . . .
