What this shows Wisol's Innovation Score is 43.1/100 (top 29% 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 Wisol?

Each dot is one of Wisol’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). Wisol’s own 9.8 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wisol's grants concentrate

Wisol Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 77.1% of grants classified under H03H (Impedance Networks, e.g. Resonant CIRCUITS; Resonators). Peak complete grant year is 2024 (8 grants) versus a trough of 2 in 2016. By volume, Wisol sits between Vionic Group LLC and WhiteStar Communications, Inc..

Wisol's three-year grant acceleration

Wisol Co., Ltd. shows 14 grants in 2022–2024 against only 8 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.
