NIPPON STEEL Corporation has 95 pending office actions in Chemistry & Materials. The portfolio spans 62 distinct examiners and 28 distinct art units, reflecting extensive prosecution activity distributed across many technical and examiner assignments. The difference between the pending workload and examiner count indicates that some examiners handle multiple matters, while the art-unit footprint remains broad.
WANG, NICHOLAS A is the busiest examiner, with 5 pending matters. This is the clearest examiner-specific concentration identified in the profile, but the overall workload remains spread across the wider examination group. Counsel should use portfolio-level tracking for deadlines and recurring chemistry or materials issues, while preserving art-unit-specific claim strategies and examiner-focused interview planning.
Based on the USPTO statutory response window for each pending office action. 19 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. 19 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 + other | 2 (2%) |
| §103 only | 48 (50%) |
| §112 only | 7 (7%) |
| Double-patenting only | 3 (3%) |
| Double-patenting + other | 7 (7%) |
| Multi-statute (no §101) | 29 (30%) |
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.
