Does more volume mean deeper claims for Wolong?

Each dot is one of Wolong’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). Wolong’s own 17.8 claims/patent is ABOVE the 13.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wolong's grants concentrate

Wolong Electric Group Co. Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 63.6% of grants classified under H02P (Control OR Regulation OF Electric Motors, Electric Generators OR Dynamo-electric CONVERTERS; Controlling Transformers, Reactors OR Choke Coils). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2019. By volume, Wolong sits between Wevo, Inc and World Champion Fantasy Inc..

Wolong's three-year grant acceleration

Wolong Electric Group Co. Ltd. shows 5 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.
