One of the most important aspects of evaluating a products liability claim is determining what types and amounts of damages you have suffered. The term "damages" is legalese for a sum of money paid to the plaintiff in a lawsuit either to compensate for some form of injury or loss or to punish the defendant for wrongdoing.
All damages fall into two basic categories: compensatory damages and punitive damages. Compensatory damages are intended to restore you to the condition you were in before the injury occurred by attaching a dollar value to each of the bad things that happened to you as a result of the injury. These damages include "economic" losses such as medical expenses, lost wages or profits, and any damage to your property. They also include certain "non-economic" losses, such as pain and suffering.
In many cases, compensatory damages are the only form of damages awarded. If a judge or jury finds that the defendant has acted particularly badly, however, you may also be entitled to punitive damages. The purpose of punitive damages is to punish a defendant for its conduct and to deter others from engaging in similar conduct. Punitive damages are roughly analogous to a fine and are calculated based on the nature of the defendant's misconduct in relation to its wealth (the idea is to make it hurt in proportion to the misconduct).
