What this shows Wood's Innovation Score is 45.1/100 (top 24% 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 Wood?

Each dot is one of Wood’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). Wood’s own 13.6 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Wood's grants concentrate

Wood Stone Corporation is a focused PatentsView assignee: 7 CPC subclasses with 62.5% of grants classified under F24C (Domestic Stoves OR Ranges ; Details OF Domestic Stoves OR Ranges, OF General Application). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Wood sits between Wirtgen America, Inc. and Woven Metal Products, Inc..

Wood's three-year grant acceleration

Wood Stone Corporation shows 3 grants in 2022–2024 against only 1 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.
