2 pending office actions • 1 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready
Membrane Solutions (Nantong) Co. Ltd. is managing 2 pending office actions in the Chemistry & Materials technology area. These actions are split between 2 distinct examiners but are both contained within 1 distinct art unit. This concentration in 1 distinct art unit suggests that the company's pending matters are technologically similar enough to be handled by the same specialized group. The 2 pending office actions are the primary focus of the applicant's current efforts in this sector.
The busiest examiner is BUI, ANH HUYNH NGOC, who is responsible for 1 pending office action. Although there are 2 distinct examiners for the 2 pending office actions, the fact that they share a single art unit may allow for some consistency in the types of prior art or legal standards applied. Practitioners should monitor both examiners closely while leveraging any art-unit-specific trends that emerge during the prosecution of these Chemistry & Materials cases. The involvement of only 1 distinct art unit simplifies the administrative oversight required for this portfolio, as all active matters are housed within the same department.
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.
