N E Chemcat Corporation is currently managing 4 pending office actions within the Chemistry & Materials technology area. These actions are distributed across 4 distinct examiners, which indicates a balanced ratio of pending matters to assigned reviewers. The portfolio is further spread across 3 distinct art units, suggesting that the company's chemical and material innovations cover a range of technical sub-specialties. This distribution requires a coordinated strategy to manage different examiner expectations across multiple departments.
The busiest examiner for this portfolio is HAILEY, PATRICIA L, who is responsible for 1 busiest examiner pending action. This specific action represents a portion of the 4 pending office actions currently facing the company. Because each of the 4 distinct examiners is likely handling a single case, the workload is evenly distributed. This lack of concentration means that no single examiner's backlog or specific tendencies will dominate the company's overall prosecution progress.
The presence of Chemistry & Materials classifications highlights the diversity of the company's portfolio. With 3 distinct art units involved, the company must address a variety of technical and procedural requirements. The 1 busiest examiner pending action assigned to HAILEY, PATRICIA L is a component of a larger, multi-faceted prosecution effort. Practitioners should be prepared to navigate the distinct standards of the assigned art units while managing the relationships with the various 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 | 2 (40%) |
| Multi-statute (no §101) | 3 (60%) |
