What rights does an assignee of the entire interest in a patent application have regarding inspection?

An assignee of the entire interest in a patent application has broader rights regarding inspection compared to a part interest assignee. According to MPEP 106.01, an assignee of the entire interest may inspect the application file wrapper and be granted access to the subject matter of the application. This is because they have acquired all rights to the patent application and are considered to have stepped into the shoes of the inventor(s) for all practical purposes related to the application.
