What this shows Westmill's Innovation Score is 37.9/100 (top 42% 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 Westmill?

Each dot is one of Westmill’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). Westmill’s own 17.1 claims/patent is ABOVE the 11.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Westmill's grants concentrate

Westmill Industries Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under F26B (Drying Solid Materials OR Objects BY Removing Liquid Therefrom). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Westmill sits between Weldon Industries, Inc. and William Evans Retail Ltd.

Westmill's three-year grant acceleration

Westmill Industries Ltd. shows 4 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.
