Hamilton Sundstrand Space Systems International Inc. maintains 8 pending office actions within the Medical Devices & Mechanical Engineering technology area. These matters are distributed across 8 distinct examiners, indicating a broad spread of oversight. The portfolio spans 6 distinct art units, which suggests that the technical subject matter is diverse enough to require review from multiple specialized groups. WEILAND, HANS R. is the busiest examiner in this portfolio, currently managing 1 pending office action.
The ratio of 8 pending office actions to 8 distinct examiners shows that no single examiner has a concentrated workload for this company. This decentralized approach means that the company must navigate different examination styles simultaneously. With the 6 distinct art units involved, the prosecution strategy likely requires expertise across several sub-specialties within the broader mechanical engineering field. The lack of examiner overlap suggests that each application is being treated as a distinct technical entity by the patent office.
For practitioners, this diversity of examiners and art units implies that there is no single point of contact or lead examiner who can influence the entire portfolio. The busiest examiner, WEILAND, HANS R., only handles the 1 pending action, reinforcing the distributed nature of the current prosecution. Success in a matter may not necessarily predict outcomes in others, given the variety of personnel involved across the art units.
Based on the USPTO statutory response window for each pending office action. 2 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 |
|---|---|
| §101 + other | 2 (29%) |
| §103 only | 3 (43%) |
| Multi-statute (no §101) | 2 (29%) |
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.
