Analysis

Daio Paper Corporation has 9 pending office actions in Chemistry & Materials. The matters span 9 examiners and 7 art units, indicating full examiner dispersion with some repetition at the art-unit level.

BERRIOS, JENNIFER A handles 1 pending matter. Counsel should therefore coordinate the docket by art unit where useful while maintaining separate examiner-specific analyses for each response.

The art-unit structure may help identify related technical issues among the actions. It does not, on the stated data, indicate a dominant examiner relationship, so docket control and consistent claim-position tracking are practical priorities.
