Pi Advanced Materials Co. Ltd. has 15 pending office actions in Chemistry & Materials. The matters involve 13 examiners across 11 art units, showing a broad docket with recurring examiner and art-unit assignments. The lower examiner and art-unit figures relative to pending matters indicate that some examination relationships and technical units cover multiple matters, creating opportunities for coordinated review.
DESTEFANO, AUDRA JEAN is the busiest examiner, with 2 pending matters. That examiner is a defined coordination point, although the overall portfolio remains distributed. Counsel should align related materials positions where useful, while tailoring claim amendments and prior-art responses to the separate examination assignments.
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 (33%) |
| §102 only | 1 (7%) |
| Multi-statute (no §101) | 9 (60%) |
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.
