Solum Co., Ltd. maintains 3 pending office actions within the Communications technology area. The portfolio is spread across 3 distinct art units, which matches the count of distinct examiners involved. This direct ratio between actions, examiners, and art units indicates that every pending matter is being handled by a different individual in a different group. Such a spread prevents the company from developing a centralized prosecution history with any single examiner.
SHEN, YUZHEN is the busiest examiner for the company, holding 1 pending office action. With only a few pending office actions total, the prosecution strategy must account for the specific tendencies of the distinct examiners. There is no central examiner or art unit currently dominating the 3 pending office actions. The Communications technology area filings appear to be technically diverse based on the variety of units involved.
Because SHEN, YUZHEN and the other distinct examiners each manage only 1 pending office action, the company faces a fragmented landscape. The pending office actions are isolated from one another by being in different art units. This structure requires a unique approach for each of the 3 pending office actions to address the specific requirements of the assigned examiners.
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 (33%) |
| Multi-statute (no §101) | 2 (67%) |
