What this shows Weston's Innovation Score is 35.6/100 (top 49% 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 Weston?

Each dot is one of Weston’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). Weston’s own 16.3 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Weston's grants concentrate

Weston Aerospace Limited is a focused PatentsView assignee: 19 CPC subclasses with 30.8% of grants classified under G01K (Measuring TEMPERATURE; Measuring Quantity OF HEAT; Thermally-sensitive Elements NOT Otherwise Provided FOR). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Weston sits between Watergen Ltd. and Wins Co., Ltd..

Weston's three-year grant acceleration

Weston Aerospace Limited shows 1 grants in 2022–2024 against only 5 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.
