NIPPON SHEET GLASS Company, Limited has 19 pending office actions in Chemistry & Materials. The matters are assigned to 17 examiners and 10 art units, showing substantial examiner dispersion alongside greater concentration within the art-unit structure.
YANG, ZHEREN J is the listed busiest examiner, with 3 pending matters. That examiner therefore represents a visible point of docket concentration, although the broader record remains spread across many other examiner relationships.
The difference between the pending-action total and examiner coverage indicates that some examiners handle multiple matters, while the art-unit figure shows that several matters are grouped within shared examination environments. Counsel can use those groupings to compare treatment of related technologies and identify opportunities for consistent argument framing.
Because the portfolio spans multiple examiners and art units, a single response template may not address every prosecution context. A practical approach is to maintain common technical positions at the portfolio level while tailoring amendments and prior-art distinctions to each examiner’s record.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 | 9 (47%) |
| Double-patenting + other | 3 (16%) |
| Multi-statute (no §101) | 7 (37%) |
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.
