Analysis

PALO ALTO RESEARCH CENTER Incorporated is managing 7 pending office actions in the Computing & Software technology area. The portfolio is highly diverse in its assignments, with 7 distinct examiners and 7 distinct art units involved in the process. This wide distribution indicates that the company is pursuing a broad range of innovations across many different sub-sectors of computing and software.

The busiest examiner, MITROS, ANNA MAE, is currently handling 1 pending action. Because each of the pending office actions is assigned to a different examiner and art unit, the company faces a broad range of examination styles and technical focuses. This distribution requires a versatile prosecution strategy to address the unique requirements of multiple points of contact. With 7 distinct examiners involved, the company cannot rely on a single relationship or strategy, but must instead tailor its approach to the specific nuances of each individual examiner and art unit within the Computing & Software field.
