CHINA PETROLEUM & CHEMICAL Corporation currently has 2 pending office actions in the Semiconductors, Circuits & Optics technology area. These 2 actions are distributed across 2 distinct examiners and 2 distinct art units, showing that the company's current patent applications are being reviewed by different individuals in separate technical groups. This distribution requires the applicant to manage two independent prosecution tracks without any overlap in examiner personnel.
BRYANT, MICHAEL CASEY is the busiest examiner for this portfolio, holding 1 pending office action. With 2 pending office actions and 2 distinct examiners, each examiner is responsible for exactly one case. The use of 2 distinct art units indicates that the technology, while within the broader Semiconductors, Circuits & Optics area, is specialized enough to fall into different classifications. Practitioners should expect that the feedback and requirements for the 2 pending office actions will be unique to each examiner and art unit, necessitating separate strategies for each filing.
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.
