Defective products injure or kill thousands of people every year. Under product liability laws, manufacturers and others along the supply chain can be held liable for any injuries or deaths caused by dangerous or defective products. Product liability lawsuits can involve various legal theories such as negligence, strict liability, and breach of warranty. Because product liability laws vary from state to state, it is important to contact a product liability lawyer as soon as possible for more information about filing a product liability claim.
