What this shows W-scope's Innovation Score is 44.6/100 (top 25% 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 W-scope?

Each dot is one of W-scope’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). W-scope’s own 11.2 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where W-scope's grants concentrate

W-scope Chungju Plant Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2021. By volume, W-scope sits between Vortex Intellectual Property Holding LLC and Wafer Mems Co., Ltd..

W-scope's three-year grant acceleration

W-scope Chungju Plant Co., Ltd. shows 4 grants in 2022–2024 against only 1 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.
