NTN Corporation has 25 pending office actions in Transportation, E-Commerce & Mechanical Systems. The matters span 18 distinct examiners and 12 art units, showing a distributed docket with meaningful reuse of both examiner and technical-assignment channels.
PILKINGTON, JAMES is the busiest examiner, with 5 pending actions. This is the clearest examiner concentration in the listed profile, making coordination across those matters particularly useful. Counsel should still account for the other examiner and art-unit contexts when developing portfolio-wide claim, evidence, and response practices.
Based on the USPTO statutory response window for each pending office action. 9 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. 9 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 | 1 (4%) |
| §101 + other | 2 (8%) |
| §103 only | 11 (46%) |
| §112 only | 2 (8%) |
| Multi-statute (no §101) | 8 (33%) |
