A rule that allows you to cancel a contract within a specified time period (typically three days) after signing it. Federal cooling-off rules apply this three-day grace period to sales made door-to-door and anywhere other than a seller's normal place of business, such as at a trade show. Another federal cooling-off rule lets you cancel a home improvement loan or second mortgage within three days of signing. Various states have cooling-off rules that sometimes apply even longer cancellation periods to specific types of sales, such as dancing lessons and timeshares.

The legally prescribed time limit in which a lawsuit must be filed. Statutes of limitation differ depending on the type of legal claim, and often the state. For example, many states require that a personal injury lawsuit be filed within one year from the date of injury -- or in some instances, from the date when it should reasonably have been discovered -- but some allow two years. Similarly, claims based on a written contract must be filed in court within four years from the date the contract was broken in some states and five years in others. Statute of limitations rules apply to cases filed in all courts, including federal court.

A statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.

A legal doctrine stating that if a person receives money or other property through no effort of his own, at the expense of another, the recipient should return the property to the rightful owner, even if the property was not obtained illegally. Most courts will order that the property be returned if the party who has suffered the loss brings a lawsuit.
