RTX Corporation has 133 pending office actions in Medical Devices & Mechanical Engineering. The portfolio includes 108 distinct examiners and 56 distinct art units, indicating extensive distribution across examination personnel and groups. That breadth creates a substantial need for consistent processes in docketing, claim review, and response preparation.
KANG, EDWIN G is the busiest identified examiner, with 5 pending matters. The identified examiner is a useful focal point, but the wider assignment pattern shows that most prosecution activity lies elsewhere. Counsel may combine targeted review of related files with portfolio-wide tracking of recurring medical-device and mechanical-engineering issues.
Based on the USPTO statutory response window for each pending office action. 22 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. 22 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 only | 1 (1%) |
| §101 + other | 6 (5%) |
| §103 only | 47 (37%) |
| §102 only | 7 (6%) |
| §112 only | 7 (6%) |
| Multi-statute (no §101) | 59 (46%) |
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.
