A legal principle or rule created by one or more decisions of a state or federal appellate court. These rules provide a point of reference or authority for judges deciding similar issues in later cases. Lower courts must apply these rules when faced with similar legal issues. For example, if the Montana Supreme Court decides that a certain type of employment contract overly restricts the right of the employee to quit and get another job, all other Montana courts must apply this same rule.

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.

Something that interferes with the use of property by being irritating, offensive, obstructive or dangerous. Nuisances include a wide range of conditions, everything from a chemical plant's noxious odors to a neighbor's dog barking. The former would be a 'public nuisance,' one affecting many people, while the other would be a 'private nuisance,' limited to making your life difficult, unless the dog was bothering others. Lawsuits may be brought to abate (remove or reduce) a nuisance. See quiet enjoyment, attractive nuisance.
