LG Energy Solution Ltd. has 812 pending office actions in Chemistry & Materials. The portfolio spans 354 examiners and 95 art units, requiring extensive coordination across a wide examination footprint.
BERNATZ, KEVIN M is the busiest examiner, with 9 pending matters. That cluster is useful for targeted coordination, but the broader docket is distributed among many other examiner relationships. Counsel should therefore rely on centralized status controls, consistent issue coding, and art-unit-specific technical review.
The scale and distribution support separating portfolio governance from individual response preparation. Central teams can identify recurring claim and prior-art themes, while matter teams preserve the context needed for examiner-specific prosecution decisions.
Based on the USPTO statutory response window for each pending office action. 181 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. 181 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 | 13 (2%) |
| §101 + other | 22 (3%) |
| §103 only | 355 (45%) |
| §102 only | 30 (4%) |
| §112 only | 9 (1%) |
| Double-patenting only | 8 (1%) |
| Double-patenting + other | 21 (3%) |
| Multi-statute (no §101) | 328 (42%) |
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.
