Nikkiso Co., Ltd. possesses a robust portfolio with 19 pending office actions in the Medical Devices & Mechanical Engineering technology area. The prosecution of these assets is highly distributed, involving 19 distinct examiners. This direct ratio of actions to examiners indicates that the company must navigate different individual examination styles, requiring a versatile and highly customized approach to each response. Because no actions are handled by the same person, the company cannot rely on a single relationship to resolve multiple pending matters.
The portfolio's reach extends across 9 distinct art units, showing that the company's mechanical and medical innovations are being reviewed by a variety of specialized technical groups. Despite the high volume of pending office actions, there is no concentration of work under any single examiner. The busiest examiner, LINFORD, JAMES ALBERT, is responsible for only 1 pending office action. This lack of examiner concentration means that no single official has a disproportionate impact on the overall portfolio's progress. Managing 9 distinct art units requires a broad understanding of different technical examination standards across the patent office.
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 |
|---|---|
| §101 only | 1 (6%) |
| §101 + other | 3 (17%) |
| §103 only | 3 (17%) |
| §112 only | 1 (6%) |
| Multi-statute (no §101) | 10 (56%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
