What is PALM in the context of patent examination?

PALM stands for Patent Application Locator and Monitoring system. While MPEP 303 doesn’t provide a definition, it mentions PALM in the context of assignment information:

“…it is necessary for the examiner to obtain assignment information from PALM.” (MPEP 303)

PALM is an internal USPTO database system used by patent examiners to access and track information about patent applications, including assignment details. It’s a crucial tool for examiners when they need to verify ownership or resolve conflicts related to patent applications.
