Bitzer Kuehlmaschinenbau GmbH maintains 6 pending office actions within the Medical Devices & Mechanical Engineering technology area. While these actions are concentrated within 1 distinct art unit, they are distributed among 6 distinct examiners. This structure suggests that while the technical subject matter remains consistent within a single administrative unit, the company must navigate the varying perspectives of 6 different individuals. The concentration in 1 art unit implies a focused technical scope, yet the diversity of examiners introduces multiple subjective interpretations of that technology.
The busiest examiner, FREAY, CHARLES GRANT, is responsible for 1 pending office action. Given that each of the 6 distinct examiners handles exactly 1 of the 6 pending office actions, the workload is balanced across the examining staff. This lack of examiner concentration requires a strategy that accounts for the individual tendencies of 6 examiners within the same art unit. Practitioners should look for internal consistency in how this specific art unit applies rules, while remaining prepared for the unique stylistic requirements of each assigned examiner.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 2 (33%) |
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 3 (50%) |
