What this shows Westlake's Innovation Score is 51.5/100 (top 11% 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 Westlake?

Each dot is one of Westlake’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). Westlake’s own 12.6 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Westlake's grants concentrate

Westlake Royal Building Products (USA) Inc. is a focused PatentsView assignee: 14 CPC subclasses with 33.3% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2024 (7 grants) versus a trough of 1 in 2021. By volume, Westlake sits between Vetnos, LLC and Wuxi Biologics Ireland Limited.

Westlake's three-year grant acceleration

Westlake Royal Building Products (USA) Inc. shows 13 grants in 2022–2024 against only 1 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.
