11 pending office actions • 7 art units • 9 examiners • 0 of 11 (0%) have an AI response strategy ready • 9 patents granted in the last 365 days
Daido Steel Co., Ltd. is managing 11 pending office actions in the Chemistry & Materials technology area. These 11 actions are distributed among 9 distinct examiners, which indicates that some examiners are handling multiple matters for the company. This spread across 9 distinct examiners suggests a wide range of examiner interactions. The portfolio is also spread across 7 distinct art units, indicating that the company's chemical and metallurgical innovations cover a broad spectrum of technical classifications.
YANG, JIE is the busiest examiner for this portfolio, currently holding 2 pending office actions. This is the highest concentration for any individual examiner, as the other distinct examiners handle the remaining pending office actions. The 7 distinct art units involved suggest that the 11 pending office actions are subject to various internal policies and prior art databases. Practitioners should coordinate their efforts to ensure that the 9 distinct examiners receive consistent arguments across the 7 different art units.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 | 6 (55%) |
| §102 only | 1 (9%) |
| Multi-statute (no §101) | 4 (36%) |
