Ngk Insulators Ltd. has 72 pending office actions in Chemistry & Materials. The portfolio spans 68 distinct examiners and 34 distinct art units, creating a substantial and widely distributed prosecution operation. Effective management requires centralized visibility into claim scope, response history, and technical support across many examination teams.
GAMBLE JR, RANDALL LEE is the busiest examiner, with 4 pending matters. That cluster provides a defined opportunity for coordinated review, but the majority of the docket remains distributed among other examiners and art units.
Based on the USPTO statutory response window for each pending office action. 7 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. 7 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 | 34 (48%) |
| §102 only | 5 (7%) |
| §112 only | 5 (7%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 2 (3%) |
| Multi-statute (no §101) | 24 (34%) |
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.
