Chemetall GmbH currently has 10 pending office actions within the Chemistry & Materials technology area. These 10 pending office actions are handled by 8 distinct examiners. The count of 10 pending office actions is higher than the count of 8 distinct examiners, showing some concentration of the workload under specific individuals.
The prosecution activity spans 8 distinct art units. This count of 8 distinct art units matches the number of 8 distinct examiners, suggesting that the company's technical interests are spread across many specialized groups. ZHENG, LOIS L is the busiest examiner, with a busiest examiner pending count of 3. This busiest examiner pending count of 3 is the highest for any single examiner in the portfolio.
For practitioners, the 10 pending office actions across 8 distinct art units require a broad understanding of different examination practices. While there are 8 distinct examiners, the concentration of 3 actions under the busiest examiner is notable for a portfolio of this size. The fact that 8 distinct art units are involved means that nearly every pending matter is being reviewed by a different technical department.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 3 (33%) |
