What this shows Zinwave'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 Zinwave?

Each dot is one of Zinwave’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). Zinwave’s own 21.2 claims/patent is ABOVE the 14.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zinwave's grants concentrate

Zinwave, Ltd is a focused PatentsView assignee: 6 CPC subclasses with 50% of grants classified under H04W (Wireless Communication Networks). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2020. By volume, Zinwave sits between Zhongying Changjiang International NEW Energy Investment Co., Ltd. and ZYA, Inc..

Zinwave's three-year grant acceleration

Zinwave, Ltd shows 2 grants in 2022–2024 against only 6 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.
