Cataler Corporation is managing 15 pending office actions in the Chemistry & Materials technology area. These filings are distributed across 6 distinct art units, which suggests a moderate level of technical concentration within the patent office. The involvement of 14 distinct examiners indicates that the company must navigate a wide variety of individual examination styles across its active applications.
The busiest examiner for this portfolio is YOUNG, NATASHA E, who is responsible for 2 of the pending actions. With 15 total pending office actions, the presence of 14 distinct examiners means that almost every case is being reviewed by a different person. This lack of examiner concentration requires a highly adaptable prosecution strategy to address the unique feedback from each of the individuals involved.
The 6 distinct art units provide some level of administrative consistency, but the high number of 14 distinct examiners remains the primary factor in the portfolio's complexity. Because YOUNG, NATASHA E only handles 2 pending actions, the vast majority of the pending office actions are being prosecuted in isolation. Practitioners should be prepared for diverse outcomes across the Chemistry & Materials area due to this broad distribution of examiners.
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 | 10 (62%) |
| Multi-statute (no §101) | 6 (38%) |
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.
