HAMILTON SUNDSTRAND Corporation has 62 pending office actions in Semiconductors, Circuits & Optics. The portfolio involves 59 examiners across 36 art units, showing broad examiner coverage and repeated activity among art units.
GBLENDE, JEFFREY A is the busiest examiner, with 2 pending matters. Because concentration at one examiner is limited, counsel should emphasize scalable docket controls, technical coordination, and art-unit-aware prosecution planning.
Based on the USPTO statutory response window for each pending office action. 16 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. 16 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 |
|---|---|
| §101 + other | 4 (6%) |
| §103 only | 17 (27%) |
| §102 only | 3 (5%) |
| Double-patenting + other | 2 (3%) |
| Multi-statute (no §101) | 38 (59%) |
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.
