What this shows Special's Innovation Score is 30.0/100 (33rd percentile 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 Special?

Each dot is one of Special’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). Special’s own 8.7 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Special's grants concentrate

Special Springs S.R.L. is a focused PatentsView assignee: 10 CPC subclasses with 86.7% of grants classified under F16F (SPRINGS; SHOCK-ABSORBERS; Means FOR Damping Vibration). Peak complete grant year is 2017 (3 grants) versus a trough of 1 in 2016. By volume, Special sits between Smsc Holdings Sarl and Statens Serum Institut.

Special's three-year grant acceleration

Special Springs S.R.L. shows 3 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.
