Sanofi S.A. manages a large portfolio of 141 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 100 distinct examiners and 39 distinct art units. This shows a significant volume of work being handled by a large group of examiners. With 100 distinct examiners involved in 141 pending office actions, the company must manage a wide variety of examiner preferences and individual styles.
FREHE, WILLIAM R is the busiest examiner, currently overseeing 5 pending office actions. The 39 distinct art units indicate that while the focus is on medical devices and mechanical engineering, the portfolio's technical applications are broad enough to trigger review by many different USPTO divisions. With 141 pending office actions in total, the company maintains a major presence in its technology area. Practitioners should note that the concentration in 39 distinct art units, compared to the 100 distinct examiners, allows for some consolidation of prosecution strategy. While individual examiner preferences will vary, the shared standards within each of the 39 art units provide a framework for managing the large volume of pending cases. This structure requires balancing the specific demands of 100 distinct examiners with the broader procedural norms of the 39 art units.
Based on the USPTO statutory response window for each pending office action. 40 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. 40 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 | 2 (1%) |
| §101 + other | 7 (5%) |
| §103 only | 27 (19%) |
| §102 only | 6 (4%) |
| §112 only | 8 (6%) |
