King Fahd University of Petroleum and Minerals has 67 pending office actions in Chemistry & Materials. The matters span 62 distinct examiners and 43 distinct art units, showing broad distribution across examination personnel and technical groups. The profile supports a coordinated portfolio process rather than reliance on a small set of examiner relationships.
ROTONDI, CONNOR JON is the busiest identified examiner, with 2 pending matters. The limited concentration at that examiner means the broader examiner and art-unit coverage remains the main operational consideration. Counsel may benefit from standardized review procedures, centralized deadline control, and technical coordination that can be adapted to the different chemistry and materials assignments.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 (3%) |
| §101 + other | 4 (6%) |
| §103 only | 18 (28%) |
| §102 only | 2 (3%) |
| §112 only | 3 (5%) |
| Double-patenting only | 5 (8%) |
| Double-patenting + other | 2 (3%) |
| Multi-statute (no §101) | 26 (40%) |
| No statute on record | 3 (5%) |
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.
