Dingyuan New Energy Technology Co. Ltd. is currently managing 13 pending office actions in the Chemistry & Materials technology area. These 13 actions are handled by 13 distinct examiners, which means every pending matter is assigned to a different individual. This high level of examiner diversity suggests that the company must adapt to many different prosecution styles across its chemistry portfolio.
The 13 pending actions are spread across 6 distinct art units, indicating a broad range of technical subject matter within the chemistry field. CHARLENE BERMUDEZ is the busiest examiner for the portfolio, although they are only responsible for 1 pending office action. This distribution shows that no single examiner dominates the company's pending workload, requiring a broad and varied approach to patent prosecution across multiple specialized art units.
The presence of 13 distinct examiners for 13 pending office actions creates a one-to-one ratio that prevents any economy of scale in examiner communications. Practitioners must treat each of the 13 cases as a unique negotiation. While the 6 art units provide some technical clustering, the overall prosecution environment remains highly fragmented, necessitating a flexible strategy to address the specific requirements of each examiner.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 | 6 (60%) |
| §112 only | 1 (10%) |
| Multi-statute (no §101) | 3 (30%) |
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.
