RICH, JOSEPHINE ELIZABETH is the busiest examiner, with 1 pending office action. While RICH, JOSEPHINE ELIZABETH is the busiest, they only handle 1 of the 3 pending office actions. The presence of 2 distinct art units suggests that the Medical Devices & Mechanical Engineering innovations are grouped into specific technical clusters. Practitioners should look for patterns within these 2 distinct art units to streamline prosecution, even though they will be interacting with 3 distinct examiners. The outcome for each case will depend on the specific interaction with each of the 3 distinct examiners, including RICH, JOSEPHINE ELIZABETH.
