Zhejiang Dunan Artificial Environment Co., Ltd. currently faces 31 pending office actions in the Computing & Software technology area. These actions are distributed among 14 distinct examiners. The workload is not evenly spread, as the 14 distinct examiners manage a total of 31 pending office actions across the portfolio.
The technical breadth of the portfolio is narrow, with all 31 pending office actions falling into 3 distinct art units. This concentration suggests that the company's current patenting activity is focused on a specific subset of Computing & Software technology. Practitioners should note that while 14 distinct examiners are involved, they are working within the same 3 distinct art units.
STCLAIR, ANDREW D is the busiest examiner for the portfolio, managing 16 pending office actions. This means that a single individual is responsible for 16 of the 31 pending office actions currently active. The prosecution of this portfolio is heavily dependent on the interactions with STCLAIR, ANDREW D, making his specific requirements a central factor for the company's legal representatives.
Based on the USPTO statutory response window for each pending office action. 19 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. 19 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 | 8 (26%) |
| §102 only | 4 (13%) |
| §112 only | 2 (6%) |
| Multi-statute (no §101) | 17 (55%) |
How the docket's pending cases split across USPTO tech-center bands.
