Tokyo Seimitsu Co., Ltd. is processing 9 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are handled by 9 distinct examiners, ensuring that no examiner is managing more than 1 pending case for the company. The portfolio is active across 4 distinct art units, suggesting a concentration of technical subject matter despite the variety of examiners.
Christina Ilona Xing is identified as the busiest examiner with 1 pending office action. This structure indicates a distributed prosecution effort across a relatively small number of specialized USPTO units. With 9 pending office actions and 9 distinct examiners, the company must manage 9 separate examiner relationships. The 4 distinct art units suggest that the 9 pending matters are technically related enough to be grouped into a few specific mechanical engineering divisions at the USPTO, which may provide some consistency in technical review.
Based on the USPTO statutory response window for each pending office action. 3 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 3 of the docket's apps have a known mailing date.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §103 only | 3 (38%) |
| Multi-statute (no §101) | 5 (62%) |
How the docket's pending cases split across USPTO tech-center bands.
