Analysis

Rxsight Inc. has 5 pending office actions in Medical Devices & Mechanical Engineering. Those matters are distributed across 4 examiners and 3 art units, creating a moderate spread across examination assignments. The portfolio therefore requires coordination across related technical issues without assuming that one examiner controls the prosecution posture.

LOPEZ, LESLIE ANN is the busiest examiner, with 2 pending matters. The remaining matters are assigned outside that examiner's docket, so counsel should combine portfolio-level consistency with examiner-specific response planning.
