Which chapter of MPEP contains the most questions regarding the examination of applications?

Chapter 700 of the Manual of Patent Examining Procedure (MPEP) is focused primarily on the examination of patent applications, making it the most relevant chapter for understanding the processes and requirements during the examination phase. This chapter includes topics such as the nature of the examination, criteria for patentability, various rejections based on prior art, and how to effectively communicate with applicants during the examination process.

Given that the examination process is at the core of patent law practice, it is understandable that this chapter would contain a significant number of questions aimed at ensuring a deep understanding of application examination. Additionally, Chapter 700 discusses important procedures and guidelines that patent examiners must follow, making it essential for those preparing for the patent bar exam to be thoroughly familiar with its contents.

In contrast, other chapters such as Chapter 400 deals with supplemental examination, Chapter 600 focuses on the application filing process, and Chapter 800 covers procedures for appeal to the Patent Trial and Appeal Board, which, while important, do not delve into the core aspects of application examination to the same extent as Chapter 700.
