What this shows Wint's Innovation Score is 37.1/100 (top 45% 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 Wint?

Each dot is one of Wint’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). Wint’s own 17.4 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Wint's grants concentrate

Wint WI Ltd is a focused PatentsView assignee: 17 CPC subclasses with 100% of grants classified under E03B (Installations OR Methods FOR Obtaining, Collecting, OR Distributing Water). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2019. By volume, Wint sits between Whitehat Security, Inc. and Wuhan Research Institute OF Posts AND Telecommunications.

Wint's three-year grant acceleration

Wint WI Ltd shows 4 grants in 2022–2024 against only 9 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.
