Does more volume mean deeper claims for Wing?

Each dot is one of Wing’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). Wing’s own 2.0 claims/patent is at or below the 11.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wing's grants concentrate

Wing Hing Manufacturing Company Limited is a focused PatentsView assignee: 1 CPC subclasses with 3.8% of grants classified under A63H (Toys, e.g. Tops, Dolls, Hoops OR Building Blocks). Peak complete grant year is 2015 (10 grants) versus a trough of 1 in 2022. By volume, Wing sits between Vortex Pipe Systems LLC and X'pole Precision Tools Inc..

Wing's three-year grant acceleration

Wing Hing Manufacturing Company Limited shows 9 grants in 2022–2024 against only 2 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.
