Carbon Holdings Intellectual Properties LLC has 4 pending office actions in Chemistry & Materials. The matters are assigned to 4 distinct examiners and 4 distinct art units, so each pending matter has a separate examiner and art-unit path.
NGUYEN, TAM M is the busiest examiner, with 1 pending matter. No examiner accounts for more than one listed matter, making portfolio-level consistency useful while still requiring matter-specific analysis. Counsel can use the art-unit distribution to identify whether claim issues arise from the technology or from separate examination contexts.
