3 pending office actions • 1 art units • 2 examiners • 0 of 3 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Fiberlite Centrifuge LLC has 3 pending office actions in the Chemistry & Materials technology area. These actions are handled by 2 distinct examiners and 1 distinct art unit. The 3 pending office actions are concentrated within a single art unit, which suggests a specific technical focus for the current applications. This concentration in 1 distinct art unit may lead to more uniform examination across the pending cases.
LIU, SHUYI S is the busiest examiner, managing 2 busiest examiner pending actions. With the total actions and the involvement of 2 distinct examiners, LIU, SHUYI S has a larger share of the workload than the other individual involved. The fact that all 3 actions are in the same art unit indicates that the examiners likely share similar technical expertise. Practitioners should focus on the preferences and past decisions of the busiest examiner, as this individual is responsible for the majority of the current pending actions. This focused prosecution strategy allows for a streamlined interaction with the patent office.
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%) |
| Double-patenting + other | 1 (33%) |
| Multi-statute (no §101) | 1 (33%) |
