What this shows S.p.e.p.'s Innovation Score is 26.2/100 (20th 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 S.p.e.p.?

Each dot is one of S.p.e.p.’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). S.p.e.p.’s own 5.0 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where S.p.e.p.'s grants concentrate

S.P.E.P. Acquisition Corp. is a focused PatentsView assignee: 6 CPC subclasses with 24% of grants classified under E05C (Bolts OR Fastening Devices FOR Wings, Specially FOR Doors OR Windows). Peak complete grant year is 2016 (9 grants) versus a trough of 1 in 2022. By volume, S.p.e.p. sits between Robotic Research, LLC and Schlumberger Norge AS.

S.p.e.p.'s three-year grant acceleration

S.P.E.P. Acquisition Corp. shows 3 grants in 2022–2024 against only 6 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.
