Zhejiang Dunan Artificial Environment Co., Ltd. has 27 pending office actions in Computing & Software. The matters are distributed among 11 distinct examiners across 5 art units, combining substantial pending activity with repeated assignments within the examination organization.
STCLAIR, ANDREW D is associated with 16 pending matters, making that examiner the principal concentration in the profile. The remaining 11 matters are assigned elsewhere, so docket management should distinguish the concentrated examiner relationship from the broader art-unit portfolio.
The profile supports a structured prosecution program. Counsel should identify common claim elements and recurring objections for the STCLAIR matters, while preserving separate strategies for the other examiner and art-unit assignments.
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 (29%) |
| §102 only | 3 (11%) |
| §112 only | 2 (7%) |
| Multi-statute (no §101) | 15 (54%) |
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.
