The Three Types of Product Defects
Product liability law recognizes three distinct types of defects. A design defect exists when the product's basic design is inherently unsafe -- even when manufactured perfectly, the product poses unreasonable risks. A manufacturing defect occurs when a specific unit departs from the product's intended design due to an error in the production process. A failure-to-warn defect (marketing defect) exists when a product carries risks that are not adequately disclosed in the product's labeling or instructions.
Many product liability cases involve multiple defect theories. A pharmaceutical drug can have an adequate design but inadequate warnings about known side effects. A power tool can be well-designed but have a specific manufacturing defect in the blade guard mechanism. Understanding which defect theory applies to your case shapes the evidence you need to collect and the legal theories you advance.
Strict Liability and What It Means for You
Most states apply strict product liability to manufacturing defects, meaning you do not need to prove the manufacturer was negligent -- only that the product was defective when it left the manufacturer's control and that the defect caused your injury. This is a significant advantage for injured consumers because proving negligence requires evidence of what the manufacturer knew and when, while strict liability focuses on the product's condition.
For design defects and failure to warn, the standard varies by state -- some apply strict liability while others require negligence proof. An experienced product liability attorney will identify which standard applies in your jurisdiction and build the case accordingly.
Evidence You Need for a Defective Product Claim
Preserve the defective product itself -- this is the single most important piece of evidence. Do not repair or discard the product. Photograph your injuries, the product, and any damage it caused. Keep all packaging, receipts, and warranty documentation. Seek medical attention immediately and ensure your injuries are thoroughly documented. Identify any witnesses to the incident.
Product liability cases typically require expert witnesses to establish the defect, its mechanism, and the causal connection to injury. Your attorney will retain engineers, safety experts, and medical professionals as needed. The cost of this expert work is typically advanced by the attorney in contingency cases and recovered from the settlement or judgment.
Who You Can Sue in a Product Defect Case
Product liability claims can be brought against any entity in the product's distribution chain: the manufacturer, component part manufacturers, distributors, wholesalers, and in many states, retailers. This broad liability framework reflects the policy judgment that all entities that profit from placing a product in commerce share responsibility for ensuring it is safe.

In cases involving products manufactured overseas, establishing jurisdiction over foreign manufacturers can be complex. The US distributor or retailer may be the practical defendant even when the foreign manufacturer bears primary responsibility for the defect.
How to Find a Defective Product Attorney
Product liability cases are handled by personal injury and products liability attorneys who typically work on contingency. The complexity of product liability cases -- requiring expert testimony and extensive investigation -- means that attorneys are selective about the cases they accept. Strong cases involve documented physical injury, a clear causal link to the defect, and a solvent defendant.

What is a product liability lawsuit?
A claim against a manufacturer, distributor, or retailer for injuries caused by a defective product. Claims can be based on design defects, manufacturing defects, or failure to warn.

For manufacturing defects in most states, no -- strict liability applies. For design defects and failure to warn, the standard varies by state.
How long do I have to sue for a defective product?
Statutes of limitations vary by state, typically 2-4 years from the injury date or date of discovery of the defect's role in causing injury.
What if I was also partly at fault?
Most states apply comparative negligence, allowing you to recover even if partly at fault, with your recovery reduced by your percentage of fault.
How much is a defective product case worth?
Case value depends on injury severity, available insurance, and the number of defendants. Serious injury cases can result in substantial recoveries; mild injury cases may have limited value.
