Nippon Telegraph and Telephone Corporation has 626 pending office actions in Networking & Security. Those matters involve 511 distinct examiners and 198 distinct art units, showing substantial examiner dispersion across a large technology portfolio.
LEE, JAI M is the busiest identified examiner, with 6 pending matters. The limited concentration represented by that examiner suggests that portfolio management should emphasize scalable review procedures, consistent responses, and technology-specific guidance across many separate prosecution relationships.
Based on the USPTO statutory response window for each pending office action. 140 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. 140 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 only | 21 (3%) |
| §101 + other | 116 (19%) |
| §103 only | 229 (37%) |
| §102 only | 75 (12%) |
| §112 only | 25 (4%) |
| Double-patenting only | 3 (0%) |
| Double-patenting + other | 1 (0%) |
| Multi-statute (no §101) | 153 (25%) |
| No statute on record | 1 (0%) |
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.
