Dingyuan New Energy Technology Co. Ltd. has 12 pending office actions in Chemistry & Materials. The matters span 12 distinct examiners and 9 distinct art units, showing broad examiner dispersion with recurring activity across some technical groups. Portfolio oversight should combine application-level tracking with coordination across the shared art-unit assignments.
BERMUDEZ, CHARLENE is the busiest examiner, with 1 pending matter. No examiner concentration is identified in the supplied data. Counsel should avoid relying on a single prosecution pattern and instead tailor responses to the individual examiner and technical context.
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 | 8 (73%) |
| §112 only | 1 (9%) |
| Multi-statute (no §101) | 2 (18%) |
