What this shows G.w.'s Innovation Score is 51.4/100 (top 11% 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 G.w.?

Each dot is one of G.w.’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). G.w.’s own 15.0 claims/patent is at or below the 18.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where G.w.'s grants concentrate

G.W. Lisk Company, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 46.2% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2015 (3 grants) versus a trough of 2 in 2018. By volume, G.w. sits between Friedrich Boysen GmbH & Co. KG and Genmab B.V..

G.w.'s three-year grant acceleration

G.W. Lisk Company, Inc. shows 4 grants in 2022–2024 against only 0 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.
