523 pending office actions • 82 art units • 293 examiners • 0 of 523 (0%) have an AI response strategy ready • 332 patents granted in the last 365 days
Samsung SDI Co., Ltd. has 530 pending office actions in Chemistry & Materials. These matters involve 304 distinct examiners and 81 distinct art units, reflecting a large and widely distributed prosecution operation. The examiner count shows that many assignments are individualized, while the art-unit count identifies recurring technical examination centers.
CHENG, VIVIAN S is the busiest examiner, with 5 pending matters. That examiner-level concentration is limited relative to the overall portfolio, but the matters may provide a useful cluster for reviewing common objections and effective response practices. Portfolio management should combine centralized issue tracking with art-unit and application-level oversight.
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 only | 3 (1%) |
| §101 + other | 14 (3%) |
| §103 only | 208 (40%) |
| §102 only | 20 (4%) |
| §112 only | 3 (1%) |
| Double-patenting only | 3 (1%) |
| Double-patenting + other | 21 (4%) |
| Multi-statute (no §101) | 247 (47%) |
| No statute on record | 4 (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.
