3D Print Innovations LLC currently manages 4 pending office actions in the Chemistry & Materials technology area. Each of these 4 actions is assigned to a different individual, as there are 4 distinct examiners involved in the prosecution. These examiners are located in 4 distinct art units, indicating that each pending application is being reviewed by a different specialized group at the patent office.
XUE H LIU is the busiest examiner for this portfolio, with 1 pending office action. Because each of the 4 distinct examiners has exactly 1 pending action, the workload is distributed equally across the group. This 1:1 ratio between the 4 pending office actions and the 4 distinct examiners suggests a diverse set of filings within the Chemistry & Materials space. Practitioners should prepare for 4 independent prosecution paths, as no single examiner or art unit oversees more than 1 of the current pending matters.
The presence of 4 distinct art units for only 4 pending office actions highlights the specialized nature of the company's technology. Xue H Liu and the other examiners will each apply the specific standards of their respective units to the applications. This decentralized environment means that success in 1 case may not necessarily predict outcomes in the others. Practitioners must tailor their arguments to the specific preferences of the 4 different examiners and the 4 units they represent.
Based on the USPTO statutory response window for each pending office action. 1 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 (33%) |
| Multi-statute (no §101) | 2 (67%) |
