50 pending office actions • 8 art units • 25 examiners • 0 of 50 (0%) have an AI response strategy ready • 38 patents granted in the last 365 days
Shenzhen First Union Technology Co., Ltd. has 48 pending office actions in Chemistry & Materials. The portfolio reaches 25 examiners across 9 art units, so its prosecution activity is distributed broadly across the examining corps and technical organization. The scale of the pending docket calls for structured matter-level tracking, consistent claim-position management, and careful coordination of response deadlines.
SPARKS, RUSSELL E is the busiest examiner, with 5 pending matters. That assignment is a visible concentration within the broader docket, but the examiner distribution shows that most prosecution activity lies elsewhere. Counsel should use centralized portfolio oversight while preserving art-unit-specific analysis for each response.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 | 18 (36%) |
| §102 only | 5 (10%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 26 (52%) |
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.
