Dowa Electronics Materials Co., Ltd. has 5 pending office actions in the Chemistry & Materials technology area. These applications are spread across 4 distinct art units, showing a high degree of technical variety for a portfolio of this size. The company works with 5 distinct examiners to move these filings forward.
NGUYEN, KHANH TUAN is the busiest examiner, holding 1 pending office action. With 5 pending office actions and 5 distinct examiners, every case is being reviewed by a different individual at the USPTO. This 1 to 1 ratio between actions and examiners suggests a decentralized prosecution strategy.
The presence of 4 distinct art units for 5 pending office actions highlights the broad technical reach of the company's current filings. Because each of the 5 pending office actions is handled by a unique examiner, the company must adapt to 5 different individual styles. This distribution limits the influence of any single examiner on the overall success of the 5 pending office actions.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 2 (40%) |
| §102 only | 1 (20%) |
