Mitsubishi Materials Corporation manages a portfolio with 24 pending office actions, primarily situated within the Chemistry & Materials technology area. These 24 actions are distributed among 19 distinct examiners, indicating a broad range of individual perspectives reviewing the company's applications. The prosecution spans 13 distinct art units, which demonstrates significant technical diversity in the subject matter being pursued within the Chemistry & Materials sector.
The busiest examiner for the portfolio is RUFO, RYAN C, who is currently handling 3 pending office actions. This count of 3 actions is a small fraction of the total 24 pending office actions, suggesting that the workload is highly decentralized across the 19 distinct examiners. Practitioners should note that while 13 distinct art units are involved, no single examiner, including RUFO, RYAN C, maintains a dominant share of the pending matters. This distribution suggests that the company's intellectual property strategy requires engagement with a wide variety of office personnel.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 |
|---|---|
| §103 only | 8 (36%) |
| Double-patenting + other | 2 (9%) |
| Multi-statute (no §101) | 12 (55%) |
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.
