ArcelorMittal has 48 pending office actions in Chemistry & Materials. The matters involve 32 distinct examiners across 16 distinct art units, indicating a substantial workload distributed through a repeated but varied examination structure. Counsel should track art-unit trends and examiner treatment together, using portfolio-level review to locate recurring issues without assuming uniform outcomes.
YANG, JIE is the busiest examiner, with 5 pending actions. That concentration is significant enough to support focused review of the assigned matters, while the broader examiner distribution calls for a wider management system. Consistent technical positions may improve efficiency, but each action should be evaluated against its own claims and record.
Based on the USPTO statutory response window for each pending office action. 15 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. 15 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 | 1 (2%) |
| §103 only | 10 (21%) |
| §112 only | 3 (6%) |
| Double-patenting + other | 5 (11%) |
| Multi-statute (no §101) | 27 (57%) |
| No statute on record | 1 (2%) |
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.
