Bayer HealthCare LLC has 26 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 25 distinct examiners across 17 distinct art units, showing broad examiner participation and repeated activity within the art-unit structure.
PAZ ESTEVEZ, GUILLERMO G is the busiest listed examiner, with 2 pending matters. The docket remains distributed beyond that assignment, so counsel should combine portfolio-wide consistency with examiner-specific review of each pending response.
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 | 4 (16%) |
| §103 only | 2 (8%) |
| §102 only | 1 (4%) |
