Schaeffler Technologies AG & Co. KG is overseeing 80 pending office actions in the Transportation, E-Commerce & Mechanical Systems technology area. This portfolio is notably diverse, spanning 32 distinct art units. The prosecution involves 75 distinct examiners, which suggests that the company's intellectual property is being scrutinized by a large and varied group of patent office personnel across these 80 pending actions. Managing 80 actions across 32 art units requires a highly organized approach to address the different technical standards and examiner behaviors encountered.
STEFANON, JUSTIN is the busiest examiner for this portfolio, with 3 pending office actions. The ratio of 80 pending actions to 75 examiners indicates that the vast majority of examiners are only reviewing few applications for the company. Practitioners must be prepared to engage with 75 distinct examiners to advance the company's 80 pending matters. The presence of 32 distinct art units highlights the broad technical scope of the company's current filings. Success in this portfolio depends on the ability to coordinate across 32 art units and address the individual tendencies of 75 different examiners.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 | 1 (1%) |
| §103 only | 27 (34%) |
| §102 only | 7 (9%) |
| §112 only | 4 (5%) |
| Multi-statute (no §101) | 41 (51%) |
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.
