Air-O Fan Products Corporation has 1 pending office action in the Medical Devices & Mechanical Engineering technology area. ZHOU, QINGZHANG is the busiest examiner for the portfolio with 1 pending action. The current prosecution activity involves 1 distinct examiner and 1 distinct art unit. This indicates a highly specific and singular focus for the active patent matter.
Having 1 pending office action under 1 distinct examiner means that the entire active portfolio is subject to the review of a single individual. For the practitioner, this simplifies the prosecution landscape, as there is only 1 set of examiner preferences to consider. The Medical Devices & Mechanical Engineering technology area can be complex, but the concentration in 1 art unit allows for a very targeted technical argument.
This profile, with 1 pending action and 1 distinct examiner, represents a very lean prosecution effort. The company's current success at the USPTO is tied to the outcome of this 1 matter handled by ZHOU, QINGZHANG. While the portfolio is not broad, the focus on a single art unit ensures that the prosecution resources are not spread thin across different technical divisions.
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.
