153 pending office actions • 46 art units • 121 examiners • 8 of 153 (5%) have an AI response strategy ready • 123 patents granted in the last 365 days
Prime Planet Energy & Solutions Inc. maintains a large portfolio with 155 pending office actions in Chemistry & Materials. These actions are distributed across 30 distinct art units, reflecting a broad and complex technical footprint that spans many different material science classifications. The involvement of 121 distinct examiners highlights the massive scale of the prosecution effort and the need to manage a vast array of individual examiner interactions. This high volume of 155 pending office actions requires a robust management system to ensure consistency across the 30 distinct art units.
RASSOULI, LILI is the busiest examiner, currently managing 3 pending office actions. Despite the high total workload, the effort is remarkably decentralized, as evidenced by the 121 distinct examiners. Navigating the various departments requires a sophisticated understanding of various examination standards across this extensive volume of matters. The busiest examiner pending count of 3 is quite low relative to the total actions, suggesting that no single examiner creates a significant bottleneck. Practitioners must coordinate strategies across numerous distinct examiners to effectively resolve the pending office actions currently in the portfolio.
Based on the USPTO statutory response window for each pending office action. 23 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. 23 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 only | 1 (1%) |
| §101 + other | 2 (1%) |
| §103 only | 75 (49%) |
| §102 only | 8 (5%) |
| Double-patenting + other | 4 (3%) |
| Multi-statute (no §101) | 63 (41%) |
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.
