What this shows Twin's Innovation Score is 39.4/100 (top 38% 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 Twin?

Each dot is one of Twin’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). Twin’s own 17.1 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Twin's grants concentrate

Twin Disc, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 36.8% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, Twin sits between Titan Trailers Inc. and Uhde Inventa-fischer GMBH.

Twin's three-year grant acceleration

Twin Disc, Inc. shows 5 grants in 2022–2024 against only 8 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.
