Chang Chun Petrochemical Co. Ltd. has 2 pending office actions within the Chemistry & Materials technology area. Both matters are assigned to 1 distinct examiner, Seth M Dumbris, creating a centralized point of contact for the company's current patent applications.
This prosecution activity is confined to 1 distinct art unit. Because Seth M Dumbris is the busiest examiner with 2 pending office actions, the company's immediate success in this technology area depends on the preferences and pace of this specific official. The concentration of these matters within 1 art unit suggests a highly specialized technical focus.
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.
