What this shows ACM's Innovation Score is 53.3/100 (top 9% 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 ACM?

Each dot is one of ACM’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). ACM’s own 17.5 claims/patent is at or below the 18.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ACM's grants concentrate

ACM Research (SHANGHAI), Inc. is a focused PatentsView assignee: 23 CPC subclasses with 87.5% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (12 grants) versus a trough of 1 in 2015. By volume, ACM sits between Zymergen Inc. and Ancestry.com DNA, LLC.

ACM's three-year grant acceleration

ACM Research (SHANGHAI), Inc. shows 25 grants in 2022–2024 against only 14 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.
