Xencor Inc.

Technology area: Biotechnology & Pharmaceuticals

7 pending office actions • 5 art units • 7 examiners • 0 of 7 (0%) have an AI response strategy ready • 13 patents granted in the last 365 days

Analysis

Xencor Inc. currently has 9 pending office actions within the Biotechnology & Pharmaceuticals technology area. The prosecution is highly individualized, as there are 9 distinct examiners assigned to these 9 actions. This one-to-one ratio between actions and examiners means that every pending matter is being handled by a different official, requiring unique responses for each. The portfolio is spread across 6 distinct art units, providing technical variety despite the small number of 9 pending office actions.

BRADLEY DUFFY is the busiest examiner with 1 pending office action, a figure that is shared by all other examiners in this portfolio. This lack of concentration suggests that Xencor Inc. must address a wide range of examiner perspectives across its 6 distinct art units. Because each of the 9 pending office actions is in the hands of a different person, the company cannot rely on a single examiner's past behavior to predict outcomes across the portfolio. The 6 distinct art units further ensure that the 9 pending office actions are subject to diverse technical scrutiny within the Biotechnology & Pharmaceuticals field.
