LG Chem Ltd. has 289 pending office actions in Chemistry & Materials. The portfolio spans 197 examiners and 76 art units, creating a large and widely distributed examination docket.
GARRETT, DAWN L handles 7 pending matters, the largest stated examiner concentration. The remainder is spread across many other assignments, so examiner-specific preparation must operate within a broader portfolio control system.
The difference between the action volume and the examiner and art-unit coverage indicates repeated activity across both levels. Counsel can use art-unit grouping to identify recurring technical or claim issues, while maintaining separate records for examiner preferences and pending objections.
For prosecution management, consistent docket data and coordinated response review are important. The portfolio’s distribution makes it useful to prioritize matters by issue and assignment rather than applying one uniform amendment strategy.
Based on the USPTO statutory response window for each pending office action. 66 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. 66 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 + other | 6 (2%) |
| §103 only | 120 (45%) |
| §102 only | 6 (2%) |
| §112 only | 15 (6%) |
| Double-patenting only | 4 (2%) |
| Double-patenting + other | 25 (9%) |
| Multi-statute (no §101) | 88 (33%) |
| No statute on record | 2 (1%) |
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.
