6 pending office actions • 4 art units • 6 examiners • 0 of 6 (0%) have an AI response strategy ready • 3 patents granted in the last 365 days
Posco Chemical Co. Ltd. currently has 6 pending office actions within the Chemistry & Materials technology area. These matters are handled by 6 distinct examiners, which means every pending case is assigned to a different individual. This lack of examiner overlap suggests that prosecution strategies must be tailored to multiple perspectives rather than a unified examiner viewpoint. Each case represents a unique interaction point within the patent office hierarchy.
The company's work is distributed across 4 distinct art units, indicating that the pending office actions involve several specialized sub-sectors of chemistry. ERWIN, JAMES M is the busiest examiner for the portfolio with 1 pending office action. Since the number of distinct examiners matches the total number of pending office actions, the workload is perfectly dispersed across the assigned staff. This distribution requires the applicant to manage 4 different art unit environments simultaneously.
Based on the USPTO statutory response window for each pending office action. 1 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 | 4 (67%) |
| Multi-statute (no §101) | 2 (33%) |
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.
