Ecopro Materials Co. Ltd. is currently prosecuting a portfolio in the Chemistry & Materials technology area. There are 2 pending office actions across the portfolio, which are being handled by 2 distinct examiners. This distribution suggests that each pending matter is receiving attention from a different official. Interestingly, both of these actions are being processed within 1 distinct art unit, indicating a high degree of technical similarity between the applications.
HOANG, NATHAN NGOC-NGOC is the busiest examiner for this applicant, with 1 pending office action currently assigned. Since there are 2 pending office actions in total, the remaining 1 action is managed by the other of the 2 distinct examiners. This concentration within 1 distinct art unit means that while the examiners differ, the technical standards and peer environment remain consistent. The 2 pending office actions represent the current hurdle for Ecopro Materials Co. Ltd. as it seeks to expand its intellectual property holdings in the Chemistry & Materials space. Managing 2 distinct examiners within a single art unit requires a strategy that ensures consistency across both pending matters.
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.
