17 pending office actions • 9 art units • 13 examiners • 0 of 17 (0%) have an AI response strategy ready • 37 patents granted in the last 365 days

Analysis

Jeol Ltd. has 17 pending office actions in Semiconductors, Circuits & Optics. The matters are assigned to 13 examiners across 9 art units, while WANG, JING is the busiest examiner with 3 pending actions.

The portfolio has broad examiner and art-unit coverage, limiting the value of a single examiner playbook. Centralized review can identify recurring technology and claim issues, but responses should be adapted to each examination setting. The busiest examiner represents only one part of a widely distributed docket.

Written from this page's own data; every figure is computed from USPTO records and verified before publication.

Case Difficulty Mix

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.
