What is a patent specification?

A patent application is accompanied by a patent specification which is a technical and legal document. The specification should fully describe the invention with the help of drawings wherever possible. The specification must be written so that a person of ordinary skill in the relevant field to which the invention pertains can understand the invention. The most important part of a patent specification is the claims. Claims define the monopoly that the applicant claims about his or her invention. A claim is a statement of technical facts expressed in legal terms defining the scope of the invention sought to be protected. Every complete specification must have at least one claim.
