102 pending office actions • 48 art units • 84 examiners • 0 of 102 (0%) have an AI response strategy ready • 95 patents granted in the last 365 days
NITTO DENKO Corporation maintains a substantial portfolio in the Chemistry & Materials technology area, with 103 pending office actions. These actions are spread across 85 distinct examiners and 35 distinct art units. This distribution indicates a broad and technically diverse prosecution strategy that avoids concentration in any single office. The presence of 35 distinct art units highlights the wide range of technical fields covered by the company's pending applications.
The busiest examiner is DUCHENEAUX, FRANK D, who is currently handling 4 pending office actions. This is a relatively low concentration, as the busiest examiner manages only a small portion of the 103 total actions. With 85 distinct examiners involved, the company must navigate a wide range of examiner perspectives and styles. This decentralized approach ensures that the 103 pending office actions are not overly dependent on the decisions of a few individuals, spreading the prosecution risk across 35 distinct art units and 85 distinct examiners. This strategy is well-suited for the complex and varied technical requirements of the Chemistry & Materials technology area.
Based on the USPTO statutory response window for each pending office action. 32 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. 32 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 | 5 (5%) |
| §103 only | 45 (44%) |
| §102 only | 3 (3%) |

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.
