DKS CO., LTD. maintains a portfolio with 9 pending office actions primarily situated in the Chemistry & Materials technology area. These matters are distributed across 6 distinct art units, showing a relatively broad technical footprint within the chemical arts. The company interacts with 8 distinct examiners, indicating that most examiners are handling individual matters for this applicant. This breadth across 6 distinct art units suggests that the company's chemical innovations span several different specialized sub-fields.
JONATHAN CREPEAU is the busiest examiner for the portfolio, currently managing 2 pending office actions. This examiner is the only one in the group of 8 distinct examiners who is responsible for 2 or more matters among the 9 pending office actions. The spread across 6 distinct art units suggests that prosecution strategies may need to be tailored to the specific practices of several different examination divisions. With 9 pending office actions in total, the company faces a diverse set of examiner perspectives across a wide range of administrative 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.

|---|---|
| §103 only | 7 (78%) |
| Double-patenting + other | 1 (11%) |
| Multi-statute (no §101) | 1 (11%) |
