Iowa State University Research Foundation Inc. is currently navigating 34 pending office actions primarily within the Chemistry & Materials technology area. These matters are spread across 24 distinct art units, showing the multi-disciplinary nature of university research. The foundation deals with 33 distinct examiners, which indicates that almost every pending application is under the review of a unique official.
Chang Yu Wang is identified as the busiest examiner for this portfolio with 2 pending office actions. This minimal concentration suggests that prosecution outcomes are likely to be influenced by a broad spectrum of examiner behaviors rather than a single individual's tendencies. The high number of 24 distinct art units relative to the total actions further emphasizes the specialized nature of each individual filing. Practitioners should expect a highly individualized examination process for each application in this portfolio.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 | 1 (3%) |
| §103 only | 7 (21%) |
| §102 only | 1 (3%) |
| §112 only | 5 (15%) |
| Double-patenting + other | 3 (9%) |
| Multi-statute (no §101) | 17 (50%) |
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.
