Jusung Engineering Co., Ltd. currently manages 13 pending office actions within the Chemistry & Materials technology area. These 13 actions are distributed across 7 distinct art units, indicating a multi-disciplinary approach to their chemical and material innovations. The involvement of 12 distinct examiners suggests that nearly every pending action is being reviewed by a different individual at the patent office. This variety of examiners can lead to different prosecution outcomes and timelines for the 13 pending actions.
CHEN, KEATH T is identified as the busiest examiner for this portfolio, currently overseeing 2 pending office actions. This concentration of 2 actions is the maximum for any single examiner assigned to the company. The remaining actions are spread among the other distinct examiners. Practitioners should note the examiner-to-action ratio, which may require an individualized strategy for each case rather than a unified approach across the 7 art units. Managing 13 pending actions with 12 different examiners means the company must adapt to many unique perspectives on patentability within the Chemistry & Materials sector.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 | 9 (69%) |
| Double-patenting + other | 1 (8%) |
| Multi-statute (no §101) | 3 (23%) |
