Does more volume mean deeper claims for WAI?

Each dot is one of WAI’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). WAI’s own 1.6 claims/patent is at or below the 8.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where WAI's grants concentrate

WAI Shing Plastic Products Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 7.1% of grants classified under A47G (Household OR Table Equipment). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, WAI sits between Vive Crop Protection Inc. and WD Racing OY.

WAI's three-year grant acceleration

WAI Shing Plastic Products Ltd. shows 3 grants in 2022–2024 against only 3 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.
