Dupont Electronic Materials International LLC has 5 pending office actions in Chemistry & Materials. The matters span 4 distinct examiners and 4 art units, indicating that at least one examiner and one art unit are associated with more than one pending matter. The docket therefore has both examiner and art-unit repetition.
TRAYWICK, ANDREW PRESTON is the busiest examiner, with 2 pending matters. That repeated assignment may support comparison of examiner treatment across those matters, while the remaining actions require separate review. Counsel should use the shared materials focus to coordinate technical positions without assuming identical examination issues.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 2 (40%) |
| §102 only | 1 (20%) |
