Kaneka Corporation has 64 pending office actions in the Chemistry & Materials technology area. These actions are reviewed by 59 distinct examiners across 33 distinct art units. THOMPSON, CAMIE S is the busiest examiner, holding 3 busiest examiner pending actions. The 33 distinct art units indicate a broad technical range within the chemical sector.
With 59 distinct examiners for the 64 pending office actions, the portfolio is highly decentralized, with very few examiners handling multiple cases. This variety in examiners means the company must navigate many different examination styles and technical standards. The 3 busiest examiner pending actions assigned to THOMPSON, CAMIE S represent a small portion of the 64 pending office actions. Practitioners should coordinate across the 59 distinct examiners to ensure consistent prosecution outcomes.
The 33 distinct art units suggest that the portfolio touches on many specialized groups within the USPTO. Managing 64 pending office actions across these units requires an understanding of the specific technical standards applied by each group. Because the 59 distinct examiners are spread across 33 distinct art units, there is significant variety in the technical scrutiny applied to the applications. This structure requires a strategy that accounts for both individual examiner preferences and art unit trends.
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 |
|---|---|
| §101 + other | 1 (2%) |
| §103 only | 27 (43%) |
| §102 only | 2 (3%) |
| §112 only | 3 (5%) |
| Double-patenting + other | 4 (6%) |
| Multi-statute (no §101) | 26 (41%) |
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.
