4 pending office actions • 3 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready • 5 patents granted in the last 365 days
3D Print Innovations LLC has 5 pending office actions distributed across the Chemistry & Materials technology area. These matters are spread among 5 distinct examiners, indicating a lack of examiner overlap across the current portfolio. The workload spans 3 distinct art units, which suggests the company's innovations touch upon several specialized sub-sectors within the broader chemistry field.
MCKANE, ELIZABETH L is identified as the busiest examiner, though she is responsible for only 1 pending office action. This distribution shows that no single examiner currently holds a majority of the company's pending cases. For the legal team, this means prosecution strategies must be tailored to 5 distinct examiners rather than a unified examiner relationship. The presence of 3 distinct art units further complicates this, as it requires familiarity with the specific examination standards of multiple USPTO divisions. This decentralized structure suggests a diverse range of chemical technologies being pursued simultaneously, requiring a broad and adaptable legal approach.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 1 (25%) |
| Multi-statute (no §101) | 3 (75%) |
