Zeon Corporation has 55 pending office actions in Chemistry & Materials. The docket spans 48 distinct examiners and 26 distinct art units, making it broad in both examiner coverage and technical assignment. The number of art units also indicates that portfolio oversight must accommodate varied examination contexts.
VO, HAI is the busiest examiner, with 4 pending matters. Although that examiner represents the largest identified concentration, the overall docket remains widely distributed, so a unified prosecution framework should be paired with examiner-specific preparation.
Based on the USPTO statutory response window for each pending office action. 12 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. 12 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 | 30 (56%) |
| §102 only | 4 (7%) |
| Multi-statute (no §101) | 20 (37%) |
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.
