Xiamen Changelight Co. Ltd. currently has 3 pending office actions within the Semiconductors, Circuits & Optics technology area. These matters are distributed across 3 distinct examiners, which means that every active case is being handled by a different official. This distribution requires the company to manage multiple separate examiner relationships simultaneously. The prosecution is also spread across 3 distinct art units, indicating a varied technical focus within the semiconductor field.
The busiest examiner for the company is MUSE, ISMAIL A, who is responsible for 1 busiest examiner pending action. Since there are 3 pending office actions and 3 distinct examiners, MUSE, ISMAIL A handles a portion of the workload. The presence of 3 distinct art units suggests that the company's filings are technically diverse enough to be assigned to different specialized groups. Successfully resolving the 3 pending office actions will require a strategy that accounts for the specific nuances of each of the 3 distinct examiners and their respective art units.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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.
