What this shows SII's Innovation Score is 28.3/100 (27th 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 SII?

Each dot is one of SII’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). SII’s own 8.8 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SII's grants concentrate

SII Crystal Technology Inc. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2015 (13 grants) versus a trough of 1 in 2020. By volume, SII sits between Shanghai Institute OF Organic Chemistry, Chinese Academy OF Sciences and Solazyme, Inc..

SII's three-year grant acceleration

SII Crystal Technology Inc. shows 1 grants in 2022–2024 against only 3 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.
