Technology area: Chemistry & Materials
3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready
Tanaka Chemical Corporation currently manages 2 pending office actions in the Chemistry & Materials technology area. These actions are split between 2 distinct examiners and 2 distinct art units. The busiest examiner, THOMAS, JAISON P, is responsible for 1 pending office action, meaning the workload is shared equally between the two assigned examiners. With 2 distinct art units involved, the company's chemical innovations are being reviewed in two different specialized groups.
For practitioners, this distribution across 2 distinct examiners means that the prosecution of each action is independent. A decision made by THOMAS, JAISON P on the 1 pending office action he handles will not necessarily affect the outcome of the other action. This structure requires a tailored approach for each of the 2 distinct art units to address their specific technical requirements and the individual tendencies of the 2 distinct examiners. Since there are 2 distinct examiners involved in the 2 pending office actions, practitioners cannot rely on a single point of contact. Instead, they must develop separate strategies for each of the 2 distinct art units to successfully resolve the pending matters. The lack of examiner overlap ensures that each of the 2 pending office actions is evaluated on its own merits within its specific technical classification.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 |
|---|---|
| §102 only | 1 (33%) |
| Multi-statute (no §101) | 2 (67%) |
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.
