GM Global Technology Operations LLC has 355 pending office actions in Chemistry & Materials. The docket spans 303 examiners and 124 art units, making it a broad prosecution operation that requires structured portfolio administration rather than isolated matter handling.
COLTON, JENNA XIANXIAN is the busiest examiner, with 6 pending matters. That assignment is a defined concentration within a much larger docket, while the remaining matters are distributed across numerous examiner and art-unit records.
For counsel, the data supports centralized deadline controls, examiner-specific issue tracking, and technology-area coordination. The breadth of assignments makes consistent reporting and escalation procedures important for identifying recurring prosecution themes.
Based on the USPTO statutory response window for each pending office action. 62 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. 62 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 |
|---|---|
| §101 only | 3 (1%) |
| §101 + other | 16 (5%) |
| §103 only | 135 (40%) |
| §102 only | 13 (4%) |
| §112 only | 5 (1%) |
| Double-patenting + other | 3 (1%) |
| Multi-statute (no §101) | 159 (47%) |
| No statute on record | 1 (0%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
