TAIYO NIPPON SANSO Corporation is managing 7 pending office actions within the Chemistry & Materials technology area. These 7 actions are distributed among 7 distinct examiners, showing that no two pending matters are currently assigned to the same individual. This one-to-one ratio between actions and examiners requires the corporation to navigate 7 different sets of examiner expectations and styles simultaneously.
The portfolio is spread across 4 distinct art units, which indicates that the chemistry and materials work involves several different technical sub-specialties. KEITH MICHAEL RAYMOND is the busiest examiner for this portfolio, though he only holds 1 pending office action. This lack of concentration suggests a diverse filing strategy where the workload is not clustered under any single examiner or art unit.
With 7 pending office actions and 7 examiners, practitioners must develop a unique approach for every case in the portfolio. The 4 distinct art units add another layer of complexity, as each unit may have its own specific interpretation of chemistry and materials standards. The fact that the busiest examiner, KEITH MICHAEL RAYMOND, has only 1 pending action underscores the highly fragmented nature of the corporation's current prosecution efforts.
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 | 2 (29%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 4 (57%) |
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.
