Micromass UK Limited has 15 pending office actions in Semiconductors, Circuits & Optics. The portfolio spans 10 distinct examiners and 4 distinct art units, showing repeated examiner and technical assignments across the active matters. This structure supports coordinated analysis of recurring claim issues and prior-art positions.
WANG, JING is the busiest examiner, with 3 pending matters. Counsel should review those applications together for consistent examiner treatment, while using the art-unit distribution to organize broader portfolio strategy and response resources.
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 |
|---|---|
| §101 + other | 2 (15%) |
| §103 only | 1 (8%) |
| §102 only | 1 (8%) |
| §112 only | 1 (8%) |
| Multi-statute (no §101) | 8 (62%) |
