Analysis

De Nora Permelec Ltd. is overseeing a company patent portfolio that currently has 2 pending office actions. This indicates a moderate level of activity, with the company pursuing multiple patent applications simultaneously. The prosecution is split between 2 distinct examiners, which introduces some variety into the feedback the company receives from the patent office.

The data shows 0 distinct art units for this portfolio, which may suggest that the applications are in a specialized category or have not yet been assigned to a standard art unit in this dataset. Despite the lack of art unit diversity, the involvement of 2 distinct examiners means that the company must navigate two different sets of examiner preferences and interpretations of patentability. This requires a more flexible prosecution approach than a portfolio with only one examiner.

SYLVESTER, KEVIN is the busiest examiner, with 1 busiest examiner pending office action. With a total of 2 pending office actions, this examiner is responsible for half of the active workload. This distribution ensures that no single examiner has complete control over the portfolio's current outcomes. Practitioners should carefully manage the interactions with both examiners to ensure consistent progress across the 2 pending office actions.
