Nchain Licensing AG is actively prosecuting 49 pending office actions within the Transportation, E-Commerce & Mechanical Systems technology area. This portfolio is widely distributed, involving 44 distinct examiners across 19 distinct art units. The high number of 44 distinct examiners relative to 49 pending office actions suggests that very few examiners are handling more than one case for the company. SCOTT MICHAEL DIROMA is the busiest examiner, yet he is responsible for only 2 pending office actions.
This lack of examiner concentration across the 19 distinct art units implies that the company's prosecution results are subject to a wide range of individual interpretations. Managing 49 pending office actions in this environment requires a versatile approach to satisfy the requirements of 44 different officials. The 19 distinct art units further diversify the regulatory landscape for the company's ongoing prosecution efforts. With 44 distinct examiners involved, the company must maintain a highly adaptable strategy for its Transportation, E-Commerce & Mechanical Systems intellectual property.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 | 5 (10%) |
| §101 + other | 19 (38%) |
| §103 only | 13 (26%) |
| §102 only | 1 (2%) |
| §112 only | 1 (2%) |
