DEXerials Corporation manages 29 pending office actions within the Semiconductors, Circuits & Optics technology area. These actions are distributed among 28 distinct examiners, showing a high degree of individual examiner engagement. The portfolio spans 11 distinct art units, which reflects a diverse range of technical applications within the semiconductor sector. This distribution across 11 art units suggests that the company's innovations are being evaluated by several different specialized groups at the patent office.
The busiest examiner, SUL, STEPHEN SANGJIN, is currently overseeing 2 busiest examiner pending actions. This is a minor portion of the 29 total pending office actions, indicating that the prosecution workload is spread broadly across the 28 distinct examiners. Practitioners should note that the ratio of 29 pending office actions to 28 examiners implies very little repetition in examiner assignments. Navigating 11 distinct art units will require familiarity with various examination styles and technical focuses. The portfolio's structure emphasizes a wide-reaching prosecution effort across the specified technology area.
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 | 13 (45%) |
| §102 only | 4 (14%) |
| §112 only | 2 (7%) |
| Double-patenting only | 1 (3%) |
| Multi-statute (no §101) | 9 (31%) |
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.
