10 pending office actions • 5 art units • 8 examiners • 0 of 10 (0%) have an AI response strategy ready • 9 patents granted in the last 365 days
Daido Steel Co., Ltd. has 9 pending office actions in Chemistry & Materials. Those matters span 8 distinct examiners and 5 distinct art units, creating a prosecution profile that is distributed across both personnel and technical examination groups.
O'KEEFE, SEAN P is the busiest examiner, with 2 pending matters associated with that examiner. The remaining activity is therefore not confined to one examiner, so counsel should maintain a coordinated portfolio view while tailoring responses to the relevant art units.
The spread across 5 art units may produce different approaches to claim scope, prior-art treatment, and formal requirements. Tracking recurring issues by examiner and art unit can help identify where arguments or amendments may be reused and where separate strategies are needed.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 5 (50%) |
| §112 only | 1 (10%) |
| Multi-statute (no §101) | 4 (40%) |
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.
