207 pending office actions • 69 art units • 179 examiners • 0 of 207 (0%) have an AI response strategy ready • 408 patents granted in the last 365 days
Stryker Corporation has 208 pending office actions in Medical Devices & Mechanical Engineering. Those matters span 179 examiners and 67 art units, reflecting substantial breadth across the medical-device examination landscape.
BECCIA, CHRISTOPHER J is the busiest examiner, with 5 pending matters. The limited concentration suggests that portfolio oversight should organize matters by technology and art unit while preserving examiner-specific response preparation where needed.
Based on the USPTO statutory response window for each pending office action. 45 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. 45 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 | 3 (1%) |
| §101 + other | 19 (9%) |
| §103 only | 74 (36%) |
| §102 only | 11 (5%) |
| §112 only | 3 (1%) |
| Double-patenting only | 6 (3%) |
| Double-patenting + other | 8 (4%) |
| Multi-statute (no §101) | 81 (39%) |
| No statute on record | 2 (1%) |
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.
