90 pending office actions • 19 art units • 52 examiners • 0 of 90 (0%) have an AI response strategy ready • 75 patents granted in the last 365 days
Posco Co. Ltd. demonstrates an extensive prosecution presence in the Chemistry & Materials technology area with 81 pending office actions. This high volume of active cases is spread across 17 distinct art units, showing a significant depth of filing in various technical niches. The management of 81 pending office actions requires a sophisticated legal strategy to handle the diverse requirements of 17 distinct art units. This broad distribution indicates that the company's research and development in chemistry are highly diversified across the patent office's technical divisions.
The company interacts with 49 distinct examiners, a figure that highlights the complexity of its current patent office engagements. KRUPICKA, ADAM C is the busiest examiner for the portfolio, overseeing 5 busiest examiner pending actions. While this examiner has the highest individual workload, the 5 actions represent only a small fraction of the total workload, indicating that the portfolio's success is distributed across 49 distinct examiners. This decentralized examination environment requires the company to maintain consistency across many different examiner relationships while navigating the specific technical standards of the Chemistry & Materials sector.
Based on the USPTO statutory response window for each pending office action. 25 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. 25 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 | 1 (1%) |
| §103 only | 38 (42%) |
| §102 only | 1 (1%) |
| §112 only | 2 (2%) |
| Double-patenting only | 1 (1%) |
| Multi-statute (no §101) | 45 (50%) |
