What this shows Union's Innovation Score is 34.2/100 (47th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Union?

Each dot is one of Union’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Union’s own 9.0 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Union's grants concentrate

Union Carbide Corporation is a focused PatentsView assignee: 14 CPC subclasses with 36.8% of grants classified under C11D (Detergent COMPOSITIONS; USE OF Single Substances AS DETERGENTS; Soap OR SOAP-MAKING; Resin SOAPS; Recovery OF Glycerol). Peak complete grant year is 2020 (6 grants) versus a trough of 1 in 2023. By volume, Union sits between ULC Robotics, Inc. and Ubiquisys Limited.

Union's three-year grant acceleration

Union Carbide Corporation shows 7 grants in 2022–2024 against only 9 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
