16 pending office actions • 3 art units • 10 examiners • 0 of 16 (0%) have an AI response strategy ready • 6 patents granted in the last 365 days
Cala Health Inc. currently manages 16 pending office actions within the Medical Devices & Mechanical Engineering technology area. These 16 actions are distributed across 12 distinct examiners and 3 distinct art units. This distribution indicates that while the workload is spread among several examiners, the technical focus is concentrated within a few specialized divisions of the patent office. The involvement of 12 distinct examiners for a relatively small number of cases suggests a variety of examination perspectives.
Erica Shengkai Lee is the busiest examiner for the portfolio, currently overseeing 4 pending office actions. This represents 4 of the 16 total pending actions for the company. The remaining 12 pending actions are spread across the other distinct examiners. With only 3 distinct art units involved for the 16 actions, practitioners will likely encounter recurring standards and technical themes across the portfolio. Managing 12 distinct examiners requires an adaptable strategy to account for different individual examination styles within these 3 art units.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 + other | 1 (6%) |
| §103 only | 8 (50%) |
| Multi-statute (no §101) | 7 (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.
