A negligence theory requires the plaintiff to prove that the defendant owed a duty to the consumer. Manufacturers do, in fact, owe a duty to the users of its products and to bystanders likely to be injured. The manufacturer also has a duty in making its product to guard against injuries likely to result from reasonably foreseeable misuse of the product. The plaintiff must also show that the manufacturer breached its duty. The plaintiff should be able to prove that a reasonable manufacturer, with knowledge or constructive knowledge of the product’s defect, would not have produced the product. The plaintiff also must prove injury and that the defendant’s breach caused the injury.
