Petróleo Brasileiro S.A. - Petrobras has 36 pending office actions in Transportation, E-Commerce & Mechanical Systems. The docket involves 35 distinct examiners and 27 distinct art units, indicating that most matters have separate examiner assignments while some technology units recur.
CEPLUCH, ALYSSA L is the busiest listed examiner, with 2 pending actions. The limited cluster does not dominate the profile, so prosecution management should emphasize consistent tracking across the broader set of examiner relationships and coordination where art-unit assignments overlap.
Based on the USPTO statutory response window for each pending office action. 15 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. 15 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 only | 2 (6%) |
| §101 + other | 6 (18%) |
| §103 only | 5 (15%) |
| §102 only | 2 (6%) |
| §112 only | 3 (9%) |
| Multi-statute (no §101) | 16 (47%) |
