What this shows CMC's Innovation Score is 51.8/100 (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 CMC?

Each dot is one of CMC’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). CMC’s own 15.6 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CMC's grants concentrate

CMC Materials LLC is a focused PatentsView assignee: 19 CPC subclasses with 72.4% of grants classified under C09G (Polishing Compositions ; SKI Waxes). Peak complete grant year is 2023 (10 grants) versus a trough of 3 in 2022. By volume, CMC sits between Celltrion Inc. and CSR Technology Holdings Inc..

CMC's three-year grant acceleration

CMC Materials LLC shows 16 grants in 2022–2024 against only 7 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.
