Central Glass Co. Ltd. has 2 pending office actions in the Chemistry & Materials technology area. These actions are assigned to 2 distinct examiners and 2 distinct art units, indicating a divided technical focus for their current prosecution. The presence of 2 distinct art units suggests that the company's chemical or material claims are being reviewed by different specialized groups. This structure requires the company to address the specific standards of two different art units simultaneously, even though the overall volume of active prosecution is low.
ZENG, LINGWEN R is the busiest examiner for the company, currently managing 1 pending office action. With 2 pending office actions in total, the workload is split evenly between the 2 distinct examiners. This lack of concentration means that no single examiner dominates the company's patent strategy. Practitioners should prepare for distinct procedural styles, as each of the 2 distinct examiners will apply their own interpretation of the Chemistry & Materials standards to the pending applications.
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.
