Parker Hannifin Corporation has 1 pending office action in the Medical Devices & Mechanical Engineering technology area. This single matter is located within 1 distinct art unit, representing a very narrow current prosecution profile for the company. The focus on a single art unit indicates that the company's active patent office interaction is limited to a specific technical classification within the broader mechanical engineering field.
The action is assigned to 1 distinct examiner, FREHE, WILLIAM R. As the busiest examiner with 1 pending office action, FREHE, WILLIAM R is the sole point of contact for the company's active patent office interactions. This indicates a highly specific and limited set of current negotiations. For the practitioner, this means that the entirety of the company's current success in this technology area depends on the outcome of a single dialogue with one examiner. There are no other pending matters to provide broader context or alternative paths for patent acquisition at this moment.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 |
|---|---|
| §103 only | 1 (14%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 5 (71%) |
