What is the “reasonable correlation” standard for computer-implemented inventions?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

The “reasonable correlation” standard for computer-implemented inventions refers to the requirement that the disclosure must provide a reasonable correlation between the claimed function and the associated structure, material, or acts described in the specification. This standard is outlined in MPEP 2164.06(c), which states:

“The examiner has the initial burden to establish a reasonable basis to question the enablement provided for the claimed invention.”

This means that for computer-implemented inventions, the specification must provide enough detail to show that the inventor possessed the invention and that one skilled in the art can make and use the full scope of the claimed invention without undue experimentation.
