# Specification

The written description portion of a patent application — everything except the claims. The specification must describe the invention in enough detail that someone skilled in the field could make and use it. It typically includes background of the invention, a summary, a description of the drawings, and a detailed description of at least one embodiment. Courts use the specification to interpret what claim terms mean.
