3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready
Tronox LLC demonstrates a distributed prosecution strategy within the Chemistry & Materials technology area. The portfolio currently contains 3 pending office actions, which are spread across 3 distinct examiners. This distribution between actions and examiners suggests that each pending matter is receiving independent review, potentially leading to varied timelines for resolution across the different filings.
The technical scope of these applications is further reflected by their placement in 3 distinct art units. This variety indicates that the company's chemistry-related innovations span multiple specialized niches within the patent office's classification system. WIECZOREK, MICHAEL P is identified as the busiest examiner, currently holding 1 busiest examiner pending office action. Given that the total number of pending actions is 3, the workload is evenly divided, as no single examiner manages more than 1 of the active cases. This distribution requires the company to navigate the specific preferences and standards of 3 separate art units simultaneously.
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 | 1 (33%) |
| Multi-statute (no §101) | 2 (67%) |
