Analysis

Changchun University Of Science And Technology currently has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 2 distinct art units and involve 2 distinct examiners. This distribution indicates that the university's research is being evaluated from multiple technical perspectives. This lack of examiner concentration means that the institution must adapt its arguments to suit different individual styles even within the same broad technology area.

Brian W Jennison is the busiest examiner for the portfolio, currently handling 1 pending office action. The presence of 2 distinct examiners and 2 art units for only 2 pending actions shows a lack of concentration in the prosecution. Each application is being handled by a different examiner in a different unit, requiring a tailored approach for each case. Practitioners should note that having 2 distinct art units for only 2 pending actions implies that each application is being scrutinized under different technical standards, requiring a high degree of versatility in prosecution strategy.
