What this shows Semisilicon's Innovation Score is 39.8/100 (top 37% 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 Semisilicon?

Each dot is one of Semisilicon’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). Semisilicon’s own 12.3 claims/patent is at or below the 15.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Semisilicon's grants concentrate

Semisilicon Technology Corp. is a focused PatentsView assignee: 9 CPC subclasses with 95.8% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2023 (8 grants) versus a trough of 2 in 2022. By volume, Semisilicon sits between Qiagen Sciences, LLC and Sungkyunkwan University Foundation FOR Corporate Collaboration of Korea.

Semisilicon's three-year grant acceleration

Semisilicon Technology Corp. shows 15 grants in 2022–2024 against only 12 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.
