14 pending office actions • 6 art units • 13 examiners • 0 of 14 (0%) have an AI response strategy ready • 78 patents granted in the last 365 days
Delta Electronics (Shanghai) Co., Ltd. has 15 pending office actions in Semiconductors, Circuits & Optics. The matters are assigned to 14 distinct examiners across 7 distinct art units, indicating a dispersed examiner structure within a more concentrated art-unit environment. Counsel can use art-unit comparisons to identify recurring issues, while treating examiner interactions separately.
LIAN, MANG TIN BIK is the busiest examiner, with 2 pending actions. The limited examiner concentration does not support relying on one examiner relationship for portfolio-wide planning. A coordinated art-unit review, combined with application-specific response drafting, is better aligned with the available profile.
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 (14%) |
| §102 only | 4 (29%) |
| Multi-statute (no §101) | 8 (57%) |
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.
