Teijin Limited is currently managing 26 pending office actions within the Chemistry & Materials technology area. These actions are spread across 25 distinct examiners, meaning that almost every examiner is handling a single case. The portfolio is further distributed across 15 distinct art units, showing a high degree of technical and administrative diversity in their current filings.
The busiest examiner, MILLER-CRUZ, EKANDRA S., is responsible for 2 pending office actions. With 26 pending actions and 25 distinct examiners, the prosecution is highly decentralized, requiring the company to manage many separate examiner relationships. Navigating 15 distinct art units requires the company to adapt to many different sets of examiner expectations and administrative practices simultaneously.
This broad distribution across the Chemistry & Materials sector reflects the wide-ranging nature of the company's current research and development efforts. The presence of so many distinct examiners means there is very little overlap in the individuals reviewing their applications. Consequently, the company must maintain a flexible prosecution strategy that can respond to the unique requirements of many different art units and examiners.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 10 (40%) |
| Double-patenting + other | 2 (8%) |
| Multi-statute (no §101) | 13 (52%) |
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.
