11 pending office actions • 9 art units • 11 examiners • 0 of 11 (0%) have an AI response strategy ready • 8 patents granted in the last 365 days
SK Ie Technology Co. Ltd. is managing 10 pending office actions in the Chemistry & Materials technology area. These matters are distributed among 10 distinct examiners, meaning every pending matter is being reviewed by a different individual. The portfolio is also spread across 8 distinct art units, showing a broad administrative footprint. Such a high number of 8 art units for the 10 pending actions indicates that the company's chemistry filings cover a wide range of specific technical classifications.
HARRIS, MARY GRACE is identified as the busiest examiner for the portfolio, currently responsible for 1 pending office action. Because the workload is perfectly uniform, no individual examiner handles more than a single case. The 8 distinct art units involved suggest that the patent office has categorized these matters into many different supervisory groups. For a practitioner, managing these pending actions across 10 distinct examiners requires navigating many different sets of examiner behaviors.
With the busiest examiner handling only 1 action, the portfolio is characterized by maximum dispersion across the patent office's personnel and administrative structures. This high level of decentralization across 10 examiners and 8 art units prevents the consolidation of prosecution strategy for the current Chemistry & Materials workload.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 |
|---|---|
| §103 only | 4 (36%) |
| Double-patenting + other | 1 (9%) |
| Multi-statute (no §101) | 6 (55%) |
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.
