Cardinal Health Inc. has 128 pending office actions in Medical Devices & Mechanical Engineering. The matters span 105 distinct examiners and 33 distinct art units, showing broad examiner distribution within a more concentrated technical organization. Counsel should use centralized docket management while preserving technical and examiner-specific prosecution strategies.
WITTLIFF, KATERINA ANNA is the busiest identified examiner, with 4 pending matters. That group may support targeted review of examiner practice and related claim issues. It does not replace the need for individualized treatment across the many other examiner assignments.
Based on the USPTO statutory response window for each pending office action. 20 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. 20 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 | 6 (5%) |
| §101 + other | 19 (15%) |
| §103 only | 31 (24%) |
| §102 only | 8 (6%) |
| Double-patenting only | 4 (3%) |
| Double-patenting + other | 4 (3%) |
| Multi-statute (no §101) | 56 (44%) |
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.
