DDP Specialty Electronic Materials US LLC has 9 pending office actions in Chemistry & Materials. The portfolio reaches 8 examiners and 7 art units, showing that prosecution is spread across multiple technical examination groups.
KATCHEVES, BASIL S is the busiest examiner, with 2 pending matters. The assignment identifies a useful point for coordination, but it does not represent the full examination footprint.
Counsel should preserve a common technical and claim strategy where appropriate while adapting responses to the different examiners and art units. The distribution makes docket-level tracking important for identifying inconsistent objections or opportunities to reuse supporting explanations.
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 |
|---|---|
| §103 only | 4 (44%) |
| Double-patenting + other | 1 (11%) |
| Multi-statute (no §101) | 4 (44%) |
