Heraeus has 4 pending office actions, involving 3 distinct examiners and 2 distinct art units in Chemistry & Materials. The action total exceeds both the examiner and art-unit totals, indicating that some examination relationships cover multiple matters.
TRAN, VIVIAN AILINH is identified as the busiest examiner, with 2 pending matters. Counsel should prioritize coordination around that examiner while managing activity across 2 art units.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 1 (25%) |
| Multi-statute (no §101) | 3 (75%) |
