Mitsubishi Gas Chemical Company, Inc. manages a portfolio in the Chemistry & Materials technology area with 60 pending office actions. These cases are assigned to 54 distinct examiners, indicating that most matters are being reviewed by different individuals. SHUKLA, KRUPA is the busiest examiner for the portfolio, currently overseeing 2 busiest examiner pending actions. The presence of 60 pending office actions suggests a high level of ongoing innovation.
The portfolio is spread across 25 distinct art units, showing a diverse range of chemical and material science applications. With 54 distinct examiners involved, the company must navigate a multitude of examination styles and interpretations. The ratio of 60 pending office actions to 25 distinct art units indicates that while the portfolio is broad, there is some concentration of filings within specific technical groups. Managing 54 distinct examiners across these 25 distinct art units requires a sophisticated approach to maintain consistency in prosecution across the 60 pending office actions.
Based on the USPTO statutory response window for each pending office action. 13 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. 13 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 (2%) |
| §103 only | 18 (30%) |
| §112 only | 1 (2%) |
| Double-patenting only | 2 (3%) |
| Double-patenting + other | 4 (7%) |
| Multi-statute (no §101) | 34 (56%) |
| No statute on record | 1 (2%) |
