Koki Holdings Co., Ltd. currently manages 12 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 10 distinct examiners and 6 distinct art units. CHUKWURAH, NATHANIEL C is the busiest examiner, currently handling 2 busiest examiner pending actions. The 6 distinct art units indicate the technical variety within the company's mechanical engineering filings.
With 10 distinct examiners for the 12 pending office actions, the workload is distributed such that most examiners handle an individual case. This distribution means the company must navigate various individual examiner styles and interpretations. The 2 busiest examiner pending actions assigned to CHUKWURAH, NATHANIEL C represent a portion of the 12 pending office actions. Practitioners should coordinate across the 10 distinct examiners to ensure consistent prosecution outcomes.
The 6 distinct art units suggest that the portfolio touches on different specialized groups within the USPTO. Managing 12 pending office actions across these units requires an understanding of the specific technical standards applied by each group. Because the 10 distinct examiners are spread across the art units, there is likely some overlap in the technical focus of the examiners. This structure requires a prosecution strategy that accounts for both individual examiner preferences and art unit trends.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 4 (33%) |
| §102 only | 4 (33%) |
| Multi-statute (no §101) | 4 (33%) |
