Fenwal Inc. manages a portfolio with 17 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 17 distinct examiners and 9 distinct art units. EDWARDS, LOREN C is the busiest examiner, currently handling 1 pending office action.
The prosecution is highly decentralized, as 17 distinct examiners are each reviewing only one of the pending office actions. This extreme dispersion means that the company must manage separate prosecution tracks, each with its own examiner preferences and timelines. The involvement of 9 distinct art units indicates a broad technical range within the company's medical and mechanical filings, requiring expertise across many different sections of the patent office.
EDWARDS, LOREN C is responsible for 1 pending office action, reflecting the wide spread of work across the examiner pool. With 17 distinct examiners and 9 distinct art units involved, no single official or technical group dominates the company's current workload. This structure minimizes the impact of any one examiner's hurdles but also requires a highly coordinated effort to maintain consistency across the pending office actions.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 (7%) |
| §103 only | 7 (47%) |
| §102 only | 1 (7%) |
| Multi-statute (no §101) | 6 (40%) |
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.
