What this shows WPT's Innovation Score is 31.9/100 (39th 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 WPT?

Each dot is one of WPT’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). WPT’s own 15.3 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where WPT's grants concentrate

WPT LLC is a focused PatentsView assignee: 12 CPC subclasses with 57.1% of grants classified under E04F (Finishing Work ON Buildings, e.g. Stairs, Floors). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2018. By volume, WPT sits between Woowa Brothers Co., Ltd. and Wuxi Biologics (SHANGHAI) Co., Ltd..

WPT's three-year grant acceleration

WPT LLC shows 2 grants in 2022–2024 against only 4 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.
