Nissan Chemical Corporation currently has 52 pending office actions within the Chemistry & Materials technology area. These 52 actions are spread across 43 distinct examiners, which indicates that most applications are being reviewed by different individuals. The portfolio is also distributed among 28 distinct art units, suggesting that the company's intellectual property in the Chemistry & Materials sector covers a variety of specialized technical sub-fields.
The busiest examiner for this portfolio is Nelson, Michael B, who is currently managing 3 of the pending office actions. This concentration of 3 actions with one examiner is relatively low, as the remaining workload is distributed among the other 43 distinct examiners. For practitioners, this decentralized environment means that the outcomes of the 52 pending office actions will be determined by a wide range of individual examiner perspectives rather than a single point of contact.
The involvement of 28 distinct art units requires a prosecution strategy that accounts for the different procedural standards within the Chemistry & Materials groups. While Nelson, Michael B handles 3 of the pending office actions, the overall portfolio's success depends on navigating the requirements of the 43 distinct examiners involved. Practitioners must be prepared to address the specific technical nuances of each of the 28 distinct art units to ensure a cohesive approach across the 52 pending actions.
Based on the USPTO statutory response window for each pending office action. 15 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. 15 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 (2%) |
| §101 + other | 3 (6%) |
| §103 only | 16 (31%) |
| §102 only | 5 (10%) |
| Double-patenting + other | 5 (10%) |
| Multi-statute (no §101) | 22 (42%) |
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.
