Daesang Corporation has 8 pending office actions in Biotechnology & Pharmaceuticals. The matters involve 7 distinct examiners and 6 distinct art units, indicating broad distribution with repeated assignments at both levels.
DIVIESTI, KARLA ISOBEL is the busiest examiner, with 2 pending office actions. That assignment provides a limited basis for examiner-specific planning, but the remaining matters require broader art-unit and application-level analysis.
Counsel should coordinate scientific terminology and prior-art positions while preserving claim-specific reasoning. The repeated art-unit assignments may support targeted review of recurring examination themes without treating the portfolio as a single prosecution file.
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 |
|---|---|
| §101 + other | 1 (14%) |
| §103 only | 3 (43%) |
| §102 only | 1 (14%) |
| Multi-statute (no §101) | 2 (29%) |
