Analysis

Lab (Xiamen) Sanitary Fittings Inc. has one pending office action in Medical Devices & Mechanical Engineering. One examiner and one art unit are associated with the matter. LANDRUM, EDWARD F is the busiest examiner, with one pending matter, so the available activity is concentrated in one examination relationship.

Counsel can use that concentration to conduct a focused review of the action, the applicable art-unit context, and the examiner’s treatment of the claims. The profile shows no parallel examiner or art-unit allocation. A targeted response strategy is therefore appropriate for the single active prosecution issue identified in the record.
