CJ CheilJedang Corporation has 84 pending office actions in Biotechnology & Pharmaceuticals. The portfolio involves 71 distinct examiners and 27 distinct art units, combining substantial examiner dispersion with recurring activity in some technical groupings.
LEBLANC, KATHERINE DEGUIRE is the busiest examiner, with 4 pending matters. That docket is a limited segment of the total workload. Counsel should coordinate recurring art-unit issues while preserving separate examiner histories and response plans for the broader portfolio.
Based on the USPTO statutory response window for each pending office action. 21 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. 21 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 |
|---|---|
| §101 only | 1 (1%) |
| §101 + other | 8 (10%) |
| §103 only | 23 (27%) |
| §102 only | 2 (2%) |
| §112 only | 10 (12%) |
| Double-patenting + other | 3 (4%) |
| Multi-statute (no §101) | 37 (44%) |
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.
