Analysis

Alto Neuroscience Inc. has 3 pending office actions in Biotechnology & Pharmaceuticals. The matters involve 3 distinct examiners and 2 distinct art units, indicating examiner coverage that extends across more than one USPTO examination group.

BAEK, BONG-SOOK is the busiest examiner, with 1 pending matter. Because that figure is not greater than the pending workload assigned to other examiners, prosecution attention is distributed rather than concentrated with one examiner. Counsel should track responses across both art units and maintain a consistent biotechnology prosecution position.
