What this shows Shin-etsu's Innovation Score is 54.0/100 (top 8% 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 Shin-etsu?

Each dot is one of Shin-etsu’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). Shin-etsu’s own 9.3 claims/patent is at or below the 17.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Shin-etsu's grants concentrate

Shin-etsu Quartz Products Co., Ltd. is a focused PatentsView assignee: 23 CPC subclasses with 77.8% of grants classified under C03B (Manufacture, Shaping, OR Supplementary Processes). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2018. By volume, Shin-etsu sits between Sciaps, Inc. and Solantro Semiconductor Corp..

Shin-etsu's three-year grant acceleration

Shin-etsu Quartz Products Co., Ltd. shows 11 grants in 2022–2024 against only 2 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.
