What Happens In A Product Liability Case?

According to a 2025 report by the Public Interest Research Group, defective products are contributing to a growing number of injuries in the U.S. Every year, many fatal accidents are linked to unsafe or recalled consumer products.

Product liability actions frequently encompass issues pertaining to faulty medical equipment, medications, automobiles, home appliances, and items designed for children. In such instances, there are allegations made against parties such as the manufacturer, distributor, supplier, or retailer that may have put the dangerous product into the market.

For a product liability case to be successful, it is normally required that the plaintiff demonstrate that the product was defective in its design, manufacture, or labeling and that such a defect led to the damage suffered.

Product liability lawyer Robert M. Lucky says that when you work with an experienced attorney, they can review all the specifics of your case and apply their legal knowledge to help you determine the grounds of your claim.

Let’s understand how product liability cases work to help consumers protect their rights after suffering harm from an unsafe product.

The Three Types of Product Defects

The organization of product liability cases revolves around the type of defect involved. The type of defect dictates what evidence matters the most, who the necessary expert witnesses are, and what type of law backs up the case.

Design defects

A design defect establishes an inherent product design flaw that renders the product unsafe when it is produced according to its design specifications. The product has a design flaw that impacts all units because the issue exists in the design measurements instead of the manufacturing process.

The plaintiff needs to demonstrate two things to prove a design defect because the product failed a risk-utility test, which showed that the risk of injury exceeded the product’s value based on its reasonable alternative design, or the product did not meet what consumers considered to be safe.

The consumer expectations test evaluates whether an ordinary person who purchases the product for normal use would find it more dangerous than expected. The risk-utility test is more common in commercial products and asks whether a safer, economically feasible alternative design was available that would have reduced or eliminated the danger.

Manufacturing defects

A manufacturing defect occurs when a specific unit departs from the intended design during production. A design shows safety because the complete manufacturing process needs to function correctly without using wrong parts or assembling components inappropriately or using materials that have been contaminated.

The plaintiff in manufacturing defect cases receives an advantage because the product appears to have failed in a manner that does not match its intended manufacturing process.

According to Orange County product liability lawyers, any product that is manufactured (automobiles, toys, machines, drugs, medical devices, consumer products of any type, etc.) is subject to strict liability in tort for manufacturing or design defects or insufficient warnings if that failure causes injury to any person.

Marketing defects (failure to warn)

A marketing defect, also known as a failure to warn, exists when a product does not show any design or manufacturing defects yet presents hidden dangers that customers must learn about because the product lacks proper safety warnings and usage instructions and safety materials.

The duty to warn applies to risks that are not obvious to the ordinary consumer and that the manufacturer knew or reasonably should have known about. This category encompasses all instances where medications lack proper labeling because the labels do not include required safety warnings and the product instructions fail to show all potential dangers associated with specific product applications.

Pharmaceutical and medical device lawsuits frequently involve marketing defect claims because manufacturers use their clinical data to identify product risks yet fail to update their product labels with this information.

In a failure-to-warn lawsuit, plaintiffs must prove two things: the existing warning did not meet requirements and an appropriate warning would have changed the sequence of events that resulted in their injury.

The Three Legal Theories: Strict Liability, Negligence, and Breach of Warranty

Product liability claims can be pursued under one or more of three legal theories, and in some cases all three may apply to the same set of facts.

The strict liability theory provides plaintiffs with their best chance of success because it assesses the product’s state instead of evaluating how the defendant behaved. A manufacturer who creates a product while exercising complete caution will face product liability under strict liability rules when their product contains defects that result in customer harm.

The existence of the defect together with the subsequent injury provides all necessary proof to establish the manufacturer’s fault. The doctrine that most U.S. jurisdictions adopted from the Restatement (Second) of Torts Section 402A establishes that manufacturers should bear the cost of defective products because they possess a better ability to handle such expenses than consumers do.

To establish negligence, the plaintiff must demonstrate that the defendant violated his duty to protect others through proper product design and manufacturing and distribution practices, which resulted in harmful outcomes. This is a higher burden than strict liability but it is sometimes the appropriate theory when the focus is on a particular decision or practice that fell below industry standards.

A product warranty breach occurs when a product does not work as stated in its express warranty or through other product description methods which include spoken and written statements and through the basic legal requirement of implied warranty that permits customers to use products for their standard purposes.

Who Can Be Named as a Defendant

Product liability law enables liability to extend beyond manufacturers who create products because all businesses involved in the product supply chain share responsibility for their products. The supply chain generally consists of these elements:

• The product designer or engineering firm that developed the design
• The manufacturer that produced the finished product • Component part manufacturers whose defective components contributed to the failure
• Distributors and wholesalers who moved the product from factory to retail
• Retailers who sold the product to the consumer
• In some cases freight brokers or companies that handled or stored the product created the defect through their operational practices. All parties involved in the supply chain who had the ability to identify and fix the defect but chose not to do so share responsibility for the defect.

Defendants in jurisdictions that practice joint and several liability face the possibility of being held responsible for the entire judgment instead of only their respective portion, which becomes crucial when some defendants possess insufficient funds or insurance coverage.

Identifying all responsible parties goes beyond being a legal requirement. The defendants in a case typically have insurance policies that protect them against various claims, which affects how much money can be recovered based on the supply chain defendants who are included in the lawsuit.

Building the Case: Evidence and Expert Witnesses

To prove a product liability claim, you will need a great deal of evidence. And to win the case, you need to prove these three things: (1) the product was defective; (2) the defect existed when the product left the control of the defendant; and (3) the defect caused the specific injury suffered by the plaintiff.

Every element of the case should have supporting documentation.

The case needs these main types of evidence:

• The defective product itself, preserved in its post-incident condition as closely as possible
• Product documentation including design specifications, engineering drawings, testing records, and manufacturing quality control logs
• Internal communications, particularly any records showing the manufacturer was aware of safety concerns or defect reports before the plaintiff’s injury
• Recall notices, safety bulletins, or complaints from other consumers about the same product or component
• Medical records documenting the injury, its treatment, and its connection to the incident
• Expert analysis, typically from engineers, safety specialists, or physicians, explaining how the defect caused the injury and what a compliant product would have looked like

Expert witnesses possess greater influence in product liability cases than non-expert witnesses. Qualified professionals need to explain three aspects of the case. Defendants typically retain their own experts, making the selection and preparation of the plaintiff’s experts a central part of case strategy.

How the Discovery Process Works

The most important part of product liability litigation occurs during its discovery stage. The defendant holds control over essential evidence, which consists of product design documents and internal testing results and communications regarding known product defects and user complaint data.

The main discovery methods used in this case include depositions taken from engineers, safety officers, and executives who developed the product, as well as document requests for internal materials.

These materials include all communications that would prove the defect of the product. This should be about the safety testing, defect complaints, risk assessment procedures, and requests to obtain records of all interactions with government agencies. They should include submissions to the Consumer Product Safety Commission, the FDA, and the NHTSA.

The defendant may attempt to limit discovery by claiming trade secrets or proprietary information. Courts are able to balance these interests against the plaintiff’s right to relevant evidence. They can also issue protective orders that allow disclosure to counsel while limiting public access.

Defenses Defendants Typically Raise

The defense strategies for product liability cases lead manufacturers and distributors to face particular legal approaches that experienced plaintiff attorneys will anticipate and counter. Common defenses include:

• Product misuse: It is when the product is used wrongly, resulting in the injury. This reduces or eliminates liability
• Comparative negligence: It is when the plaintiff’s own conduct contributed to the injury. In most states, the courts award damages proportionally rather than eliminating the claim
• State-of-the-art: The product reflected the highest level of safety knowledge available at the time it was designed and no feasible alternative design existed
• Statute of limitations: The claim was filed outside the permissible window. Generally, filing a claim runs two to four years from the date of injury or discovery depending on the state and the theory of recovery
• Government standards compliance: The product met all applicable regulatory requirements, though this is generally not an absolute defense and courts assess whether compliance was sufficient given the actual risk

The statute of limitations issue deserves special attention in product liability cases involving latent injuries. Conditions that hazardous substances or defective medical devices or pharmaceutical products created may remain hidden for several years following the initial exposure.

The discovery rule begins the limitations period when the victim finds out about their injury or when they should have reasonably discovered it instead of using the actual time of the injury.

Damages Available in Product Liability Cases

The plaintiff who suffers injury can obtain complete compensation for their damages after defendant liability has been proven. The amount of compensatory damages encompasses all economic losses, which include medical expenses for both past and future treatment, lost wages, decreased earning capacity, and expenses required to handle permanent disability costs.

Non-economic damages provide financial compensation for pain and suffering, emotional distress, disfigurement, and loss of enjoyment of life.

Defendants who demonstrate behavior that exceeds normal standards of negligence face the possibility of punitive damages, which function to penalize them while preventing similar future offenses. Companies receive punitive damages when defendants show evidence that they understood their products contained defects yet chose to hide this information while selling their items without issuing safety warnings to consumers.

The particular legal cases produce major verdicts that draw public attention, showing how juries make decisions by using evidence that proves companies choose to prioritize their financial interests instead of protecting their customers.

Product Liability Claims Require Early Action

The court case for product liability requires three types of proof, which include the defective product, the corporate documents, and the reports of the original incident. The evidence must be available at the beginning of the case. Discarding products occurs when they reach their end of life.

Document retention procedures lead to the permanent loss of documents that organizations schedule for their standard maintenance. Witnesses may leave the location and miss taking their accounts.

In this case, it’s important to consult a product liability attorney immediately after an injury from a suspected defective product. This way, you can maintain all possible legal paths and avoid missing out on filing the case.
