Definition

Liability, Market Share refers to a legal doctrine in product liability cases where companies may share legal responsibility proportionally to their market share of a particular product even if they did not produce the exact item in question. This concept ensures that all producers of a specific product type assume a portion of liability for any harm caused by that product. The division of liability is typically based on the market share each company holds.

Examples

  1. Pharmaceutical Industry: Suppose multiple pharmaceutical companies manufacture a type of medication linked to adverse side effects. Under the market share liability theory, each company would be liable for damages equivalent to their respective market shares of the medication, even if the affected consumer cannot identify the specific producer of the drug that caused the side effect.

  2. Asbestos Cases: In cases where numerous manufacturers produced asbestos-containing materials, courts might impose liability on all manufacturers based on their market share since identifying the exact source of harm is difficult.
