7 pending office actions • 4 art units • 7 examiners • 0 of 7 (0%) have an AI response strategy ready • 31 patents granted in the last 365 days
SiFive Inc. operates in the Computing & Software technology area with 7 pending office actions currently active. These actions are handled by 7 distinct examiners, meaning each pending action is being reviewed by a different individual. This lack of examiner overlap suggests that prosecution outcomes are subject to the varied interpretations of multiple staff members.
The portfolio is distributed across 4 distinct art units, which is fewer than the number of distinct examiners involved. This concentration indicates that while the examiners are unique, they are grouped within a limited number of technical departments. TSENG, CHENG YUAN is the busiest examiner for the company, currently overseeing 1 pending office action.
Because the busiest examiner only manages a single action, the workload is perfectly distributed across the examining staff. Practitioners must navigate the specific nuances of 4 distinct art units while addressing the individual feedback from the examiners to resolve the current workload of 7 pending office actions.
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 | 4 (57%) |
| §102 only | 1 (14%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 1 (14%) |
