43 pending office actions • 14 art units • 34 examiners • 0 of 43 (0%) have an AI response strategy ready • 63 patents granted in the last 365 days
MASIMO Corporation manages 44 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 14 distinct art units, indicating a concentrated focus on medical technology. The 14 art units involved suggest that while the technology is focused, it still spans a variety of mechanical and medical classifications within the patent office.
The company works with 34 distinct examiners on these matters. WINAKUR, ERIC FRANK is the busiest examiner, overseeing 4 pending actions. With 44 actions and 34 examiners, the portfolio shows some examiner overlap, though most examiners are still only handling a solitary pending matter. The 4 actions assigned to WINAKUR, ERIC FRANK represent a notable portion of the total pending workload.
The distribution of 44 pending office actions among 34 examiners across 14 art units creates a prosecution environment where some consistency may be possible. While 34 different examiners are involved, the presence of a busiest examiner with 4 actions indicates that certain technical areas are more concentrated. Practitioners can use the data from these 4 actions to identify potential trends in how WINAKUR, ERIC FRANK evaluates the company's medical device innovations.
Based on the USPTO statutory response window for each pending office action. 13 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. 13 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 | 1 (2%) |
| §101 + other | 6 (14%) |
| §103 only | 16 (37%) |
| §112 only | 1 (2%) |
| Double-patenting only | 6 (14%) |
| Double-patenting + other | 4 (9%) |
| Multi-statute (no §101) | 9 (21%) |
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.
