Legal Definitions - rule of operation

A rule of operation is a method of using a machine to produce its intended useful result. It is what distinguishes a machine from an article of manufacture.

• Using a blender to make a smoothie by adding ingredients and pressing the blend button is an example of a rule of operation.
• Operating a car by turning the key in the ignition, pressing the gas pedal, and shifting gears is another example of a rule of operation.

These examples illustrate how a machine is used to produce a specific result by following a set of steps or rules. Without these rules of operation, the machine would not be able to perform its intended function.
