What this shows WAH's Innovation Score is 30.4/100 (34th 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 WAH?

Each dot is one of WAH’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). WAH’s own 11.7 claims/patent is ABOVE the 7.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where WAH's grants concentrate

WAH Hong Industrial Corp. is a focused PatentsView assignee: 8 CPC subclasses with 33.3% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2022. By volume, WAH sits between W-scope Korea Co., Ltd. and Walmsley Developments PTY Ltd.

WAH's three-year grant acceleration

WAH Hong Industrial Corp. shows 1 grants in 2022–2024 against only 0 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.
