Daikin Industries Ltd. manages a volume of 205 pending office actions within the Chemistry & Materials technology area. This workload is distributed across 134 distinct examiners, indicating a broad engagement with the patent office's examining corps. The portfolio spans 53 distinct art units, which reflects a wide range of technical sub-specialties and classification categories within the broader chemistry field.
The busiest examiner for this portfolio is YAGER, JAMES C, who is currently handling 12 busiest examiner pending office actions. While this is a significant number, it is part of a much larger total of 205 pending office actions managed by 134 distinct examiners. This distribution suggests that prosecution outcomes are influenced by a variety of individual examiner styles. Practitioners must coordinate strategies across 53 distinct art units to ensure consistency in claim construction across this expansive portfolio. The scale of 205 pending office actions across 53 distinct art units requires an organized approach to manage the diverse requirements of each unit and examiner.
Based on the USPTO statutory response window for each pending office action. 61 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. 61 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 | 1 (0%) |
| §101 + other | 4 (2%) |
| §103 only | 95 (47%) |
| §102 only | 12 (6%) |
| §112 only | 7 (3%) |
| Double-patenting only | 2 (1%) |
| Double-patenting + other | 6 (3%) |
| Multi-statute (no §101) | 72 (36%) |
| No statute on record | 3 (1%) |
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.
