Cirrus Logic International Semiconductor Ltd. has 38 pending office actions in Semiconductors, Circuits & Optics. The matters span 35 distinct examiners and 24 distinct art units, indicating a broad prosecution footprint across both individual examiners and technical groups.
KOTOWSKI, LISA MICHELLE is the busiest listed examiner, with 2 pending matters. No single examiner accounts for a large share of the listed workload, so portfolio management should emphasize consistent claim strategy, coordinated disclosures, and examiner-specific issue tracking across the distributed docket.
Based on the USPTO statutory response window for each pending office action. 6 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 6 of the docket's apps have a known mailing date.
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 | 5 (13%) |
| §103 only | 5 (13%) |
| §102 only | 1 (3%) |
| §112 only | 3 (8%) |
| Double-patenting only | 2 (5%) |
| Double-patenting + other | 3 (8%) |
| Multi-statute (no §101) | 19 (50%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
