Gigaphoton Inc. is currently managing 24 pending office actions within the Semiconductors, Circuits & Optics technology area. These actions are distributed among 16 distinct examiners, indicating that several examiners are handling multiple applications for the company. The prosecution activity spans 6 distinct art units, showing a concentration of technical subject matter within the broader semiconductor and optics field. This volume of activity requires a coordinated strategy across multiple specialized groups.
RIDDLE, CHRISTINA A is the busiest examiner for this portfolio, overseeing 5 pending office actions. This represents a significant portion of the 24 total pending actions, suggesting that this examiner's decisions have a notable impact on the company's overall prosecution success. The presence of 16 distinct examiners for 24 actions means that while some work is concentrated, there is still a diverse range of examiner interactions. Practitioners should balance the influence of the busiest examiner against the broader group of 16 examiners and 6 distinct art units.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 (4%) |
| §101 + other | 1 (4%) |
| §103 only | 12 (52%) |
| §102 only | 2 (9%) |
| §112 only | 1 (4%) |
| Double-patenting only | 1 (4%) |
| Multi-statute (no §101) | 5 (22%) |
