Ebb Carbon Inc. is currently navigating 2 pending office actions within the Chemistry & Materials technology area. The portfolio's activity is distributed across 2 distinct examiners and 2 distinct art units, showing an even distribution between examiners and art units. This indicates that the pending matters are likely covering different specialized sub-sectors within the broader chemistry field, each requiring a unique technical focus to address the specific requirements of the 2 distinct art units.
The busiest examiner for the company is ELLINGTON, MARRIAH C G, who is assigned 1 pending office action. With 2 pending office actions and 2 distinct examiners, the workload is divided across the portfolio. This arrangement requires monitoring 2 different sets of examiner preferences and art unit trends, as the 2 distinct art units may have varying internal guidelines or timelines for response. The lack of overlap between the examiners suggests that the company is pursuing diverse technological paths that do not converge under a single reviewer.
Based on the USPTO statutory response window for each pending office action. 1 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 |
|---|---|
| §112 only | 1 (50%) |
| Multi-statute (no §101) | 1 (50%) |
