Analysis

Cb&I Sts Delaware LLC manages a patent portfolio in the Medical Devices & Mechanical Engineering technology area. The data identifies 2 pending office actions currently in progress. This volume suggests a targeted level of active prosecution for the company's mechanical engineering innovations.

The prosecution effort is spread across 2 distinct examiners and 2 distinct art units. This ratio between actions, examiners, and art units indicates that each of the 2 pending office actions is being handled in a different technical division of the patent office. Such a distribution suggests that the company's technology is multidisciplinary and touches on two separate specialized areas within medical devices and engineering.

ORTIZ, RAFAEL ALFREDO is the busiest examiner for this portfolio, with 1 busiest examiner pending office action. Since each of the 2 pending office actions is assigned to a different person among the 2 distinct examiners, the workload is evenly distributed.
