Cala Health Inc. has 16 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 11 distinct examiners and 3 distinct art units, showing examiner dispersion within a more limited set of examination groups.
LEE, ERICA SHENGKAI is the busiest identified examiner, with 6 pending matters. That examiner represents a meaningful focal point in the available profile, while the remaining matters still require coordination across other examiners. Counsel may use examiner-specific review for this cluster and maintain art-unit-level consistency for claim amendments and technical arguments throughout the medical-device portfolio.
Based on the USPTO statutory response window for each pending office action. 8 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. 8 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 |
|---|---|
| §103 only | 9 (69%) |
| §112 only | 1 (8%) |
| Multi-statute (no §101) | 3 (23%) |
