Analysis

Taisei Kako Co. Ltd. currently has 5 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are being reviewed by 5 distinct examiners, which means that every pending action is under the supervision of a different individual. This lack of examiner overlap suggests that the company must manage five separate sets of expectations and communication styles simultaneously.

The prosecution is spread across 3 distinct art units. This indicates that while the examiners are all different, some of them are working within the same art units, which may provide some level of consistency in the legal standards applied to the applications. KESSLER JR, THOMAS JOSEPH is the busiest examiner for the portfolio, currently handling 1 busiest examiner pending office action. This examiner is responsible for 1 of the 5 pending office actions currently active.

The strategy for Taisei Kako Co. Ltd. involves navigating 5 distinct examiners across 3 distinct art units. Since KESSLER JR, THOMAS JOSEPH only manages 1 busiest examiner pending action, the applicant's success is not overly dependent on any single examiner. Instead, the company must focus on the specific requirements of all 5 distinct examiners to resolve the 5 pending office actions currently on the docket.
