Hanon Systems has 46 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 36 examiners and 15 art units, showing substantial volume, repeated examiner assignments, and a comparatively concentrated technical distribution. The portfolio therefore supports both examiner-level pattern analysis and art-unit-level planning.
CIRIC, LJILJANA V is the busiest identified examiner, with 6 pending matters. That concentration provides a clear target for reviewing recurring objections and response outcomes, while the remaining docket requires coordination across many examiners. Counsel should pair centralized claim and disclosure management with tailored strategies for the most active examiner and each relevant art unit.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 (2%) |
| §103 only | 9 (20%) |
| §102 only | 4 (9%) |
| §112 only | 5 (11%) |
| Multi-statute (no §101) | 27 (59%) |
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.
