Stryker Corporation manages 221 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 195 distinct examiners, reflecting a broad range of individual examiner perspectives. SHIRSAT, MARCELA is the busiest examiner, currently handling 5 pending actions.
The portfolio is active in 58 distinct art units. This shows a significant technical breadth within the medical device field, as the 221 pending office actions are being reviewed across many different divisions. The ratio of 195 distinct examiners to the 221 pending office actions indicates that most examiners are only reviewing a single case.
With 58 distinct art units involved, Stryker's innovations are being evaluated by many different specialized groups within the USPTO. The busiest examiner workload of 5 pending actions is a minimal concentration given the 221 total pending office actions. This broad distribution across 195 distinct examiners and 58 distinct art units suggests a highly decentralized prosecution process.
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 | 22 (10%) |
| §103 only | 72 (33%) |
| §102 only | 13 (6%) |
| §112 only | 4 (2%) |
| Double-patenting only | 8 (4%) |
| Double-patenting + other | 10 (5%) |
| Multi-statute (no §101) | 81 (38%) |
| 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.
