Product liability laws are concerned with establishing responsibility for defective products that cause personal injury and determining where in the production and distribution of that product the defect occurred. These laws extend to any product that proves to be unreasonably and unforeseeably dangerous when used for its intended purpose, including defective drugs.

Product Design Defect vs Product Manufacturing Defect

A product liability design defect occurs when even if the product is assembled exactly to specifications it will be dangerous due to its design. A product liability case based on a design defect alleges that although the design of the product may have been adequate, errors were made during its manufacture that then lead to injury. Overworked assembly lines are often attributes to caused product manufacture defects.
