The “Disclosure of Invention” section is a crucial part of a patent application. According to MPEP 1823, this section should be structured to provide a clear and complete description of the invention. The MPEP states:

“The invention must be disclosed in such a way as to allow the technical problem and the solution to be understood.”

The structure of this section typically includes:

• Technical Problem: Clearly state the problem the invention solves.
• Solution to the Problem: Describe how the invention addresses the problem.
• Advantageous Effects: Explain the benefits or improvements provided by the invention.
• Brief Description of Drawings: If applicable, reference and briefly explain any drawings.
• Best Mode: Disclose the best mode contemplated by the inventor for carrying out the invention.

The disclosure should be sufficiently detailed to enable a person skilled in the art to understand and implement the invention.
