Prime Polymer Co. Ltd. has 6 pending office actions in Chemistry & Materials. The matters involve 5 examiners and 6 art units, so the art-unit distribution is broader than the examiner distribution. Counsel should maintain centralized oversight while recognizing that most matters occupy distinct examination settings.
XU, JIANGTIAN is the busiest examiner, with 2 pending matters. Those matters provide the clearest opportunity for examiner-specific issue tracking, while the other assignments call for responses tailored to their respective examination contexts.
Based on the USPTO statutory response window for each pending office action. 2 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 | 4 (57%) |
| §102 only | 1 (14%) |
| Multi-statute (no §101) | 2 (29%) |
