The Manual of Patent Examining Procedure (MPEP)

The Manual of Patent Examining Procedure (MPEP) is a comprehensive guide used by patent examiners and attorneys. It outlines the rules, procedures, and best practices for reviewing patent applications, ensuring consistency and fairness in granting patents. The MPEP covers how to evaluate whether an invention is new, useful, and non-obvious, and provides instructions on handling legal and technical issues during the patent process. Essentially, it serves as a detailed handbook that helps maintain standards and clarity in patent examination within the United States Patent and Trademark Office (USPTO).
