When do patent examiners need to obtain assignment information?

Patent examiners need to obtain assignment information in specific situations where the ownership of an application is significant. The MPEP 303 outlines two key scenarios:

  1. Conflicting claims in applications of different inventors: When multiple applications from different inventors contain claims that conflict with each other.
  2. Questions about who should direct prosecution: When there is uncertainty about which party has the right to control the patent prosecution process.

In these cases, the MPEP states: “When the assignment condition of an application is significant, such as when applications of different inventors contain conflicting claims or there is a question as to who should direct prosecution, it is necessary for the examiner to obtain assignment information from PALM.” PALM refers to the USPTO’s Patent Application Location and Monitoring system.
