FURDGE, LARRY L is the busiest examiner, with 1 pending matter. Counsel should compare treatment across the three art units for recurring mechanical or device-related issues while tailoring responses to the individual examiner and cited references.
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 only | 1 (20%) |
| §103 only | 1 (20%) |
| Multi-statute (no §101) | 2 (40%) |
| No statute on record | 1 (20%) |
