LIU & LIU works in Semiconductors, Circuits & Optics and has 1,727 career applications. Its current docket includes 8 pending office actions, providing a direct workload indicator for matters still requiring prosecution attention.
The resolved allowance rate is 87.37%, while allowances have required an average of 3.18 office actions. Together, these figures suggest that successful outcomes are common in the recorded portfolio, although reaching allowance generally involves multiple examination responses. Practitioners assessing this profile can use the combination of portfolio scale, current workload, and prosecution effort to evaluate fit for semiconductor, circuit, and optics matters.
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 |
|---|---|
| §101 + other | 1 (12%) |
| §103 only | 3 (38%) |
| Multi-statute (no §101) | 4 (50%) |
