55 pending office actions • 13 art units • 36 examiners • 0 of 55 (0%) have an AI response strategy ready • 78 patents granted in the last 365 days
ArcelorMittal is managing 55 pending office actions in the Chemistry & Materials technology area. These 55 actions are spread across 13 distinct art units, reflecting a broad range of chemical and material innovations. The company deals with 36 distinct examiners, which indicates that many examiners are handling multiple cases for the firm. This distribution across 13 art units and 36 examiners requires a prosecution strategy that balances different examiner temperaments and art unit standards. The 55 pending office actions represent a significant volume of work.
YANG, JIE is the busiest examiner, overseeing 5 pending office actions. This count of 5 actions is the highest for any single examiner in the portfolio. The remaining actions are managed by the other distinct examiners. With 55 pending actions spread across 36 examiners, there is some concentration of knowledge, but the majority of the 55 pending office actions are handled by unique individuals. Practitioners should focus on the 5 actions under YANG, JIE while also addressing the broader group of 36 distinct examiners. The 13 distinct art units provide the technical framework for these 55 pending office actions.
Based on the USPTO statutory response window for each pending office action. 18 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. 18 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 (4%) |
| §103 only | 9 (16%) |
| §112 only | 6 (11%) |
| Double-patenting + other | 7 (13%) |
| Multi-statute (no §101) | 30 (55%) |
| 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.
