Technology area: Chemistry & Materials
25 pending office actions • 8 art units • 17 examiners • 0 of 25 (0%) have an AI response strategy ready • 67 patents granted in the last 365 days
Posco currently manages 25 pending office actions within the Chemistry & Materials technology area. These 25 pending office actions are distributed among 17 distinct examiners, which represents a broad range of individual perspectives reviewing the company's applications. The prosecution activity is further spread across 8 distinct art units, indicating that the technical subject matter within Chemistry & Materials is quite diverse.
The busiest examiner for Posco is WANG, NICHOLAS A, who is currently responsible for 4 busiest examiner pending office actions. While this examiner has the largest individual workload, the 4 busiest examiner pending office actions are a small part of the total count. This distribution across the 17 distinct examiners suggests that the portfolio's success is not overly dependent on any individual examiner's discretion.
For practitioners, the involvement of 8 distinct art units requires a versatile approach to patent prosecution. The company must navigate the specific requirements and tendencies of the various examiners to resolve the pending matters. Having WANG, NICHOLAS A manage 4 busiest examiner pending office actions provides a point of focus, but the overall strategy must remain broad to accommodate the wide variety of art units involved.
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 |
|---|---|
| §103 only | 13 (52%) |
| §112 only | 2 (8%) |
| Double-patenting + other | 1 (4%) |
| Multi-statute (no §101) | 9 (36%) |
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.
