Zimmer Inc. currently has 18 pending office actions in the Medical Devices & Mechanical Engineering technology area. These 18 actions are distributed among 16 distinct examiners. The work is concentrated within 4 distinct art units, indicating that the company's mechanical and medical innovations fall into a relatively small number of technical categories.
SIPP, AMY R. is the busiest examiner for Zimmer Inc., currently managing 2 pending office actions. The ratio of 18 pending office actions to 16 distinct examiners suggests that most applications are handled by different individuals. However, the concentration in 4 distinct art units means that although 16 examiners are involved, they likely share similar technical guidelines within their respective units. This allows for some level of consistency in prosecution across the 18 pending matters.
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 | 3 (17%) |
| §103 only | 3 (17%) |
| §102 only | 1 (6%) |
| §112 only | 2 (11%) |
| Multi-statute (no §101) | 9 (50%) |
