59 pending office actions • 30 art units • 56 examiners • 0 of 59 (0%) have an AI response strategy ready • 219 patents granted in the last 365 days
Hamamatsu Photonics K.K. has 55 pending office actions in Semiconductors, Circuits & Optics. The matters span 53 distinct examiners and 30 distinct art units. The portfolio therefore combines extensive examiner dispersion with repeated art-unit activity. Prosecution management requires a strong central process for deadlines, disclosures, claim positions, and response quality, alongside detailed monitoring of unit-specific practices.
TOOHEY, RICHARD ORLANDO is the busiest examiner, with 2 pending matters. No examiner controls a large portion of the overall workload. Counsel should use the repeated art-unit assignments to identify useful patterns without assuming that examiner outcomes will be uniform, and should preserve application-specific analysis for each technical record.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 | 6 (10%) |
| §103 only | 20 (34%) |
| §102 only | 3 (5%) |
| §112 only | 2 (3%) |
| Double-patenting only | 1 (2%) |
| Double-patenting + other | 4 (7%) |
| Multi-statute (no §101) | 23 (39%) |
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.
