Product liability is a type of legal theory based on a defective or dangerous product. Companies that manufacture or sell products generally have a legal duty to make sure the products they offer are free from defects that present an unreasonable risk of harm to consumers. If a product turns out to be dangerous or defective, the person injured may have a products liability claim and can sue for damages. Generally, product defects include: manufacturing defects, design defects and defective warnings. It is important to understand that product liability law is very complex and just because a product was involved in an injury does not automatically mean there is a valid case against the manufacturer. A skilled products liability attorney can help you determine whether or not you have a valid case.
