Fujikura Ltd. maintains a presence in the Semiconductors, Circuits & Optics technology area with 23 pending office actions. This volume is distributed across 19 distinct examiners, suggesting a broad prosecution strategy that utilizes many individual reviewers. The workload is further spread across 8 distinct art units, reflecting the technical diversity of the company's current filings.
The distribution of cases is relatively even, as the busiest examiner, RAHLL, JERRY T, is responsible for 2 pending office actions. With 23 pending office actions and 19 distinct examiners, the portfolio involves many different examination styles. The presence of 8 distinct art units indicates that the innovations are being evaluated by several specialized groups within the office, requiring a multi-faceted approach to prosecution.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 (5%) |
| §103 only | 7 (32%) |
| §102 only | 1 (5%) |
| Multi-statute (no §101) | 13 (59%) |
