What Are the Elements of a Per Se Illegal Tying Claim Under the Antitrust Laws?

January 30, 2020

When a seller requires buyers to purchase a second product or service as a condition of obtaining a first product or service, it may run afoul of the federal antitrust laws. This is called a tying arrangement or tying agreement.

You can read our article at The Antitrust Attorney Blog on tying here.

Importantly, unlike other selling conditions like loyalty discountsbundling, and exclusive dealing, for example, tying arrangements may, under certain situations, create per se antitrust liability. This departure from these other “vertical” agreements is due largely to the coercive aspect of tying that creates an all-or-nothing proposition for customers and may successfully foreclose competitors from competing to serve those customers.

Classifying an antitrust claim as a per se antitrust violation is significant because the plaintiff need not show anticompetitive harm as the law presumes that per se antitrust violations create anticompetitive harm with no redeeming competitive value. Per se antitrust violations are typically limited to price-fixing, market allocationbid-rigginggroup boycott (in some instances) and, as explained here, certain forms of tying.

A typical tying arrangement is when a seller with market power for a product (the “tying” item) requires any customer buying that item to also purchase a second item (the “tied” item). The market for the tied item is usually competitive and the seller is using its market power for the first item (the "tying" item) to increase sales in the competitive market for the second item.

This tying arrangement may present competitive problems because alternative sellers of the second item—the tied product—may find themselves foreclosed from competing because buyers are coerced into buying a product from the first seller because the buyers may need the product in which the seller has market power (the first product). It is the only way buyers can obtain the second item—by also buying the first product from the seller.

Although the explanation above refers to products, tying arrangements may include either products or services.

Negative tying also violates the antitrust laws. That occurs where a seller conditions the sale of one product (the Tying Product) on the buyer agreeing not to purchase a second product (the Tied Product) from a competitor.” Please link the entire first sentence to the following article:

Below are the elements that a plaintiff must prove to prevail on a tying claim as a per se antitrust violation:

  1. The two products or services must, in fact, be separate products or services. In many cases a plaintiff can easily satisfy this element because the products or services are obviously separate products with separate demand and existences. But in some situations, the products or services work so closely together that it isn’t at all clear whether they are separate or one.
  2. Coercion: A buyer can only obtain the second product or service by purchasing the first product or service. By contrast, a bundling arrangement is one where the seller offers buyers a discount for purchasing two or more products or services together, but the buyer may still purchase them separately (without the discount).
  3. Appreciable Economic Power: The seller’s economic power for the first item (the tying product or service) must “appreciably restrain free competition” in the market for the second item (the tied product or service).This is a lower standard than market or monopoly power.
  4. Substantiality: The tying arrangement must affect a “not insubstantial” amount of commerce in the market for the second product or service. The level of “substantial” for this element is not great, but an arrangement with limited impact on the competitive market may lead a court to dismiss the claim under this element.
  5. The seller must have an economic interest in the two items (products or services) that it offers.
