Analysis

Quest Diagnostics Investments LLC is currently managing 7 pending office actions within the Biotechnology & Pharmaceuticals technology area. These 7 pending office actions are distributed among 7 distinct examiners, which indicates that each active case is being evaluated by a different individual. This distribution means that the company prosecution experience is not concentrated under 1 official.

The busiest examiner for this portfolio is FRITCHMAN, REBECCA M, who is responsible for 1 pending office action. Since the total of 7 pending office actions is spread across 7 distinct examiners, FRITCHMAN, REBECCA M handles a portion of the workload that is equal to the other examiners involved. This creates a decentralized prosecution environment where the company must address the specific feedback of 7 different people.

The involvement of 5 distinct art units means that the technical review is conducted across different specialized groups at the patent office. With 7 distinct examiners and 5 distinct art units, the company must navigate various procedural preferences and technical standards. The company must tailor its responses to the specific requirements of the 5 distinct art units involved in the prosecution of these cases.
