Which chapter of the MPEP discusses secrecy and access regarding patent applications?

The chapter of the Manual of Patent Examining Procedure (MPEP) that addresses secrecy and access concerning patent applications is Chapter 100. This chapter outlines the fundamental principles related to patent application secrecy, including the procedures and policies related to the handling of confidential information submitted by applicants. The focus in this chapter is on the statutory requirements for maintaining secrecy, particularly for applications that may be sensitive due to national security concerns or involve classified information.

Understanding this chapter is crucial for applicants and practitioners as it lays the groundwork for who can access patent applications, the obligations of the U.S. Patent and Trademark Office (USPTO) regarding the confidentiality of applications, and the potential implications of disclosing sensitive information. This foundational knowledge helps ensure compliance with federal regulations and informs filing strategies for applicants who may be dealing with inventions that require careful management of confidential information.
